This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## What This Project Does
RSIPI enables real-time control of KUKA industrial robots from Python via the RSI (Robot Sensor Interface) protocol. The robot sends its position ~250 times/second over UDP, and this library lets you send back position corrections to control the robot externally.
## Build & Development Commands
```bash
# Install dependencies
pip install -e .
# Or install from requirements (if present)
pip install pandas>=2.0 numpy>=1.22 matplotlib>=3.5 lxml>=4.9 scipy>=1.8
# Run the CLI
python -m RSIPI.rsi_cli --config RSI_EthernetConfig.xml
# Run the echo server (for offline testing without a real robot)
python -m RSIPI.rsi_echo_server
```
**No test suite exists** - testing is done via the echo server simulation and example scripts in `examples/`.
## Architecture
### Core Communication Flow
```
KUKA Robot Controller <--UDP/XML--> NetworkProcess <--multiprocessing.Manager--> RSIClient <-- RSIAPI/CLI
```
1. **NetworkProcess** (`network_handler.py`) - Runs in separate process via `multiprocessing.Process`. Binds to UDP socket, receives XML from robot, parses into `receive_variables`, sends XML from `send_variables` back to robot. Uses `start_event` to wait for explicit start signal.
2. **RSIClient** (`rsi_client.py`) - Orchestrates the system. Initializes ConfigParser, SafetyManager, and NetworkProcess. Uses `multiprocessing.Manager` dicts for thread-safe variable sharing between processes.
3. **RSIAPI** (`rsi_api.py`) - High-level API wrapping RSIClient. Runs RSIClient in a daemon thread. Provides trajectory planning, logging, plotting, and safety controls.
4. **RSICommandLineInterface** (`rsi_cli.py`) - Interactive CLI that wraps RSIAPI.
### Key Shared State
Variables are shared between processes using `multiprocessing.Manager().dict()`:
- `send_variables` - Values to send to robot (RKorr corrections, digital outputs, etc.)
- `receive_variables` - Values received from robot (RIst position, ASPos joints, IPOC timestamp)
### Configuration
`RSI_EthernetConfig.xml` defines:
- Network settings (IP, port) in `<CONFIG>` section
- Send variables in `<SEND><ELEMENTS>` - what the robot receives from us
- Receive variables in `<RECEIVE><ELEMENTS>` - what we receive from robot
Variable tags like `DEF_RIst` get the `DEF_` prefix stripped and are expanded using `internal_structure` in ConfigParser to full dicts (e.g., `RIst: {X, Y, Z, A, B, C}`).
### Safety Layer
**SafetyManager** (`safety_manager.py`) validates all outgoing values against configurable limits. Can load limits from `.rsi.xml` files. Supports emergency stop and safety override modes.
### Trajectory Execution
`TrajectoryPlanner` generates interpolated waypoints. `execute_trajectory()` in RSIAPI uses asyncio to send points at specified rate (default 12ms for Cartesian, 400ms for joints).
## Important Patterns
- **IPOC synchronization**: The robot sends an IPOC (timestamp) value. The response must include `IPOC + 4` to maintain sync. This is handled automatically in `NetworkProcess.process_received_data()`.
- **Lazy client initialization**: RSIAPI uses `_ensure_client()` pattern - RSIClient is created on first use, not at RSIAPI instantiation.
- **Non-blocking start**: `start_rsi()` runs the client loop in a daemon thread. The NetworkProcess waits on `start_event` before binding the socket.
## File Locations
- Source code: `src/RSIPI/`
- Example scripts: `examples/`
- Config template: `RSI_EthernetConfig.xml`
- Logs written to: `logs/` (created at runtime)

GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.
GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
RSI-PI
Copyright (C) 2025 adam
This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.

# Phase 2: Network Reliability - Complete
## Summary
Successfully implemented comprehensive network reliability infrastructure for RSIPI. The library now provides real-time performance monitoring, automatic connection recovery, and long-duration stability testing capabilities - essential for industrial robot control applications requiring 24/7 operation.
## What Changed
### Network Monitoring and Diagnostics
The RSIPI library now tracks detailed timing and network quality metrics in real-time:
1. **Timing Instrumentation** - Records cycle time, jitter, and latency with minimal overhead
2. **IPOC Gap Detection** - Identifies missed packets via IPOC sequence analysis
3. **Packet Loss Tracking** - Monitors communication reliability with percentage metrics
4. **Watchdog Timer** - Detects communication timeouts (>1 second without packets)
5. **Health Monitoring** - Real-time health status with threshold-based warnings
### Automatic Reconnection
New auto-reconnection manager provides graceful recovery from network failures:
1. **Background Monitoring** - Checks watchdog status every 2 seconds
2. **Configurable Retry Strategies**:
- IMMEDIATE: Reconnect without delay
- LINEAR_BACKOFF: Incremental retry delays (5s, 10s, 15s, ...)
- EXPONENTIAL_BACKOFF: Exponential retry delays (5s, 10s, 20s, 40s, ...)
3. **Connection Verification** - Validates successful reconnection with health checks
4. **Statistics Tracking** - Records reconnection attempts, failures, and timestamps
5. **Event Callbacks** - Optional callbacks for reconnection success/failure
### Long-Duration Testing
24-hour stability test infrastructure for validating production-readiness:
1. **Configurable Duration** - Run tests from minutes to days
2. **Sample Collection** - Records metrics at configurable intervals (default: 60s)
3. **Real-Time Logging** - Progress updates with health status and warnings
4. **JSON Reports** - Comprehensive statistical analysis of test results
5. **Graceful Interruption** - Handles KeyboardInterrupt, always generates report

self.timing_metrics.record_cycle(ipoc)
update_counter += 1
if update_counter >= 100:
self._update_metrics_dict()
update_counter = 0
```
### [src/RSIPI/rsi_client.py](rsi-pi/src/RSIPI/rsi_client.py)

**Key Changes:**
```python
# Added imports
from .auto_reconnect import AutoReconnectManager, ReconnectStrategy
# New constructor parameters
def __init__(

auto_reconnect_delay: float = 5.0
) -> None:
# Created shared metrics dict
self.metrics_dict = self.manager.dict()
# Pass to NetworkProcess
self.network_process = NetworkProcess(..., self.metrics_dict)
# Initialize auto-reconnect manager
if enable_auto_reconnect:
self.auto_reconnect_manager = AutoReconnectManager(
client=self,
enabled=True,
max_retries=auto_reconnect_retries,
retry_delay=auto_reconnect_delay,
strategy=ReconnectStrategy.LINEAR_BACKOFF
)
# In start() method

self.auto_reconnect_manager.stop()
```
### [src/RSIPI/diagnostics_api.py](rsi-pi/src/RSIPI/diagnostics_api.py)
**Fully implemented DiagnosticsAPI (was placeholder in Phase 5):**
- `get_stats()` - Comprehensive network and performance statistics
- `get_timing()` - Timing-specific metrics (cycle time, jitter)
- `get_network_quality()` - Network quality metrics (packet loss, IPOC gaps)
- `is_healthy()` - Overall system health check
- `get_warnings()` - Active warning messages
- `check_watchdog()` - Watchdog timeout status
- `format_stats()` - Human-readable statistics output
## Example Usage
### Basic Diagnostics
```python
from RSIPI import RSIAPI
api = RSIAPI('RSI_EthernetConfig.xml')
api.start()
# Check overall health
if api.diagnostics.is_healthy():
print("✅ Network healthy")
else:
print("⚠️ Network issues detected")
for warning in api.diagnostics.get_warnings():
print(f" - {warning}")
# Get timing metrics
timing = api.diagnostics.get_timing()
print(f"Mean cycle time: {timing['mean_cycle_time']*1000:.2f}ms")
print(f"Jitter: {timing['jitter']*1000:.2f}ms")
# Get network quality
network = api.diagnostics.get_network_quality()
print(f"Packet loss: {network['packet_loss_rate']:.2f}%")
print(f"IPOC gaps per 1000 cycles: {network['ipoc_gap_rate']:.1f}")
# Print formatted statistics
print(api.diagnostics.format_stats())
api.stop()
```
### Auto-Reconnection
```python
from RSIPI import RSIAPI
# Enable auto-reconnection with unlimited retries
api = RSIAPI(
'RSI_EthernetConfig.xml',
enable_auto_reconnect=True,
auto_reconnect_retries=0, # 0 = unlimited
auto_reconnect_delay=10.0 # 10 second initial delay
)
api.start()
# Auto-reconnection will now handle any communication failures
# Monitor will check watchdog every 2 seconds
# Will attempt reconnection with linear backoff (10s, 20s, 30s, ...)
# Your application code here...
api.stop() # Stops auto-reconnect monitor gracefully
```
### Custom Reconnection Callbacks
```python
from RSIPI import RSIAPI
from RSIPI.auto_reconnect import ReconnectStrategy
def on_reconnect_success():
print("✅ Reconnected successfully!")
# Re-initialize application state, restart trajectories, etc.
def on_reconnect_failure():
print("❌ Reconnection failed after max retries")
# Send alert, log failure, initiate shutdown, etc.
api = RSIAPI('RSI_EthernetConfig.xml')
api.start()
# Manually configure auto-reconnect with callbacks
from RSIPI.auto_reconnect import AutoReconnectManager
api.auto_reconnect_manager = AutoReconnectManager(
client=api,
enabled=True,
max_retries=10,
retry_delay=5.0,
strategy=ReconnectStrategy.EXPONENTIAL_BACKOFF,
on_reconnect=on_reconnect_success,

## Metrics Tracked
### Timing Metrics
| Metric | Description | Units |
|--------|-------------|-------|
| `mean_cycle_time` | Average time between packets | seconds |
| `std_cycle_time` | Standard deviation of cycle time | seconds |
| `min_cycle_time` | Minimum cycle time observed | seconds |
| `max_cycle_time` | Maximum cycle time observed | seconds |
| `jitter` | Cycle time variance (std_dev) | seconds |
### Network Quality Metrics
| Metric | Description | Units |
|--------|-------------|-------|
| `packet_loss_rate` | Percentage of packets lost | percent |
| `ipoc_gap_rate` | IPOC gaps per 1000 cycles | gaps/1000 cycles |
| `total_cycles` | Total communication cycles | count |
| `total_packets_lost` | Total packets lost | count |
| `total_ipoc_gaps` | Total IPOC discontinuities | count |
### Health Indicators
| Indicator | Threshold | Description |
|-----------|-----------|-------------|
| `is_healthy` | All checks pass | Overall system health |
| `watchdog_timeout` | >1 second | Communication timeout detected |
| High jitter | >2ms | Excessive timing variance |
| High packet loss | >1% | Network reliability issue |
| High cycle time | >6ms (1.5x expected) | Performance degradation |
## Health Thresholds
The system is considered **healthy** when:
- No watchdog timeout (packets received within last 1 second)
- Jitter < 2ms (timing variance acceptable)
- Packet loss < 1% (minimal data loss)
- Mean cycle time < 6ms (within 1.5x expected 4ms)
Violations of any threshold trigger:
- Warning messages in log
- `is_healthy()` returns False
- Warning list populated with specific issues
## Performance Impact
**Timing Metrics Collection:**
- Per-cycle overhead: ~10 microseconds (timestamp + IPOC append)
- Shared dict update: Every 100 cycles (~400ms) to minimize overhead
- Total impact: <0.1% on 250Hz real-time loop
- No GIL contention (metrics calculated in NetworkProcess)
**Auto-Reconnection Monitoring:**
- Background thread sleeps 2 seconds between checks
- Reconnection attempt: ~3-5 seconds (stop, wait, start, verify)
- Zero impact during normal operation (thread sleeping)
## Architecture Details
### Multiprocessing Design
```
Main Process (RSIAPI)
├── Manager.dict() (shared metrics_dict)
├── RSIClient
│ ├── AutoReconnectManager (if enabled)
│ │ └── Background Thread (monitors watchdog every 2s)
│ └── NetworkProcess (separate process)
│ ├── TimingMetrics
│ │ ├── Records IPOC + timestamp each cycle
│ │ └── Updates shared dict every 100 cycles
│ └── UDP Communication Loop (250Hz)
└── DiagnosticsAPI
└── Reads from shared metrics_dict
```
**Key Design Decisions:**
1. **Separate Process for Network**: Avoids Python GIL, guarantees real-time performance
2. **Shared Manager.dict()**: Inter-process communication for metrics
3. **Batched Updates**: Only update shared dict every 100 cycles to minimize overhead
4. **Deferred Statistics**: Heavy calculations (mean, stdev) done on-demand, not per-cycle
## Migration Notes
### No Breaking Changes
Phase 2 is **fully backward compatible** with Phase 1 & 5 API:
- All existing code continues to work without modification
- Auto-reconnection is opt-in via constructor parameter
- DiagnosticsAPI methods are new additions (no conflicts)
### Opt-In Auto-Reconnection
```python
# Old code (still works, no auto-reconnect)
api = RSIAPI('RSI_EthernetConfig.xml')
# New code (with auto-reconnect)
api = RSIAPI(
'RSI_EthernetConfig.xml',
enable_auto_reconnect=True,
auto_reconnect_retries=0, # unlimited
auto_reconnect_delay=5.0
)
```
## Benefits of Phase 2
1. **Production-Ready Reliability**: Automatic recovery from network failures
2. **Real-Time Diagnostics**: Comprehensive metrics without performance impact
3. **Early Warning System**: Detect network degradation before failures occur
4. **Validation Infrastructure**: 24-hour stability testing for production deployments
5. **Research Quality**: Publication-ready performance metrics and analysis
## Phase 2 Status: ✅ COMPLETE
All planned features have been implemented:
- ✅ Timing instrumentation (latency, jitter, cycle time tracking)
- ✅ Watchdog timer for communication loss detection
- ✅ Network quality monitoring (packet loss, IPOC gaps)
- ✅ CSV logging optimization (batched updates)
- ✅ Auto-reconnection with graceful recovery
- ✅ 24-hour stability test infrastructure
## Next Steps
### Immediate Actions
1. Run actual 24-hour stability test with real robot hardware
2. Collect performance metrics for publication
3. Document any issues discovered during long-duration testing
### Phase 3: KRL Coordination (Upcoming)
- High-level Digital I/O API (set_output, get_input, pulse)
- KRL state coordination helpers (wait_for_signal, signal_complete)
- Parameter passing via Tech variables
- KRL code templates for coordination scenarios
- Enhanced inject_rsi_to_krl with coordination boilerplate
The `api.io` and `api.krl` namespaces will be enhanced with Python-KRL coordination features to enable seamless bidirectional communication between RSIPI and KRL programs.

# Phase 4: Advanced Motion Control - Implementation Summary
**Date**: January 17, 2026
**Phase**: 4 of 6
**Status**: ✅ Complete
---
## Overview
Phase 4 adds professional-grade motion planning capabilities to RSIPI, enabling industrial applications requiring complex trajectories, optimized timing, and flexible coordinate systems. This phase focuses on trajectory generation, velocity profiling, geometric primitives, path blending, and coordinate transformations.
## What Was Implemented
### 1. Velocity Profiling
**File**: `src/RSIPI/motion_api.py`
**New Method**: `generate_velocity_profile()`
Generate time-optimal velocity profiles for trajectory execution with configurable acceleration limits.
```python
profiled_trajectory = api.motion.generate_velocity_profile(
trajectory=waypoints,
max_velocity=200.0, # mm/s
max_acceleration=500.0, # mm/s²
profile='trapezoidal' # or 's-curve'
)
# Returns: List[Tuple[Dict[str, float], float]]
# Each element: (waypoint, time_delta)
```
**Features**:
- **Trapezoidal Profile**: Bang-bang acceleration with constant velocity cruise phase
- Fast point-to-point motion
- Time-optimal for given velocity/acceleration limits
- Suitable for pick-and-place, navigation
- **S-Curve Profile**: Jerk-limited smooth acceleration transitions
- Reduced mechanical stress and vibration
- Smooth motion for delicate operations
- Better for assembly, inspection, coating
**Implementation**:
- Calculates Euclidean distances between waypoints
- Determines acceleration, constant velocity, and deceleration phases
- Handles both full trapezoidal and triangular (short distance) profiles
- S-curve uses sine function for smooth jerk limiting
- Returns trajectory with precise timing for each waypoint
---
### 2. Geometric Motion Primitives
**File**: `src/RSIPI/motion_api.py`
#### 2.1 Arc Generation
**New Method**: `generate_arc()`

center={"X": 100, "Y": 0, "Z": 500},
radius=50.0,
start_angle=0, # degrees
end_angle=90, # degrees
steps=50,
plane='XY' # or 'XZ', 'YZ'
)
```
**Features**:

steps=100,
plane='XY'
)
```
**Features**:

```python
# Expanding spiral (drilling)
spiral_expand = api.motion.generate_spiral(
center={"X": 100, "Y": 0, "Z": 500},
start_radius=5.0,
end_radius=40.0,
pitch=10.0, # mm per revolution (positive = descending)
revolutions=3.0,
steps=150,
plane='XY',
axis='Z'
)
# Contracting spiral (retraction)
spiral_contract = api.motion.generate_spiral(
center={"X": 100, "Y": 0, "Z": 470},
start_radius=40.0,
end_radius=5.0,
pitch=-10.0, # negative = ascending
revolutions=3.0,
steps=150,
plane='XY',
axis='Z'
)
```
**Features**:
- Variable radius (expanding or contracting)
- Configurable pitch (positive/negative for descending/ascending)
- Multiple plane and axis combinations
- Continuous motion from start to end
**Use Cases**:
- **Expanding**: Hole drilling, pocket milling, large hole boring
- **Contracting**: Tool retraction from deep holes, spiral unwinding

---
### 3. Path Blending
**File**: `src/RSIPI/motion_api.py`
**New Method**: `blend_trajectories()`
Create smooth transitions between trajectories using cubic Hermite spline interpolation.
```python
traj1 = api.motion.generate_trajectory(p0, p1, steps=50)
traj2 = api.motion.generate_trajectory(p1, p2, steps=50)
blended = api.motion.blend_trajectories(
traj1=traj1,
traj2=traj2,

blend_steps=20 # Interpolation points in blend zone
)
```
**Features**:
- Cubic interpolation for smooth velocity transitions
- Configurable blend zone radius
- Handles position and orientation blending
- Eliminates stop-and-go at trajectory junctions
**Implementation**:
- Automatically finds blend points based on radius
- Uses cubic Hermite spline with zero endpoint velocities
- Interpolates all axes (X, Y, Z, A, B, C, A1-A6)
- Preserves trajectory before/after blend zones
**Benefits**:
- **Reduced cycle time**: Eliminates stops at corners
- **Better quality**: No witness marks in welding/machining
- **Mechanical benefits**: Lower stress, reduced vibration
- **Consistent process**: Constant velocity through transitions

## Usage Patterns
### Basic Velocity Profiling
```python
# Generate trajectory
trajectory = api.motion.generate_trajectory(p0, p1, steps=100)
# Apply velocity profile
profiled = api.motion.generate_velocity_profile(
trajectory,
max_velocity=200.0,
max_acceleration=500.0,
profile='s-curve'
)
# Execute with precise timing
for waypoint, dt in profiled:
api.motion.update_cartesian(**waypoint)
time.sleep(dt)
```
### Geometric Primitives
```python
# Generate drilling pattern
spiral = api.motion.generate_spiral(
center={"X": 100, "Y": 0, "Z": 500},
start_radius=5.0,
end_radius=40.0,
pitch=10.0,
revolutions=3.0,
steps=150,
plane='XY',
axis='Z'
)
# Execute

```
### Path Blending
```python
# Generate segments
seg1 = api.motion.generate_trajectory(p0, p1, steps=50)
seg2 = api.motion.generate_trajectory(p1, p2, steps=50)

blended = api.motion.blend_trajectories(
seg1, seg2,
blend_radius=20.0,
blend_steps=20
)
# Execute continuous motion
api.motion.execute_trajectory(blended, space='cartesian', rate=0.02)
```

pallet_offset = {
"X": 800.0,
"Y": -300.0,
"Z": 50.0,
"A": 0.0,
"B": 0.0,
"C": 30.0
}

pick_point_pallet,
from_frame='WORK',
to_frame='BASE',
frame_offset=pallet_offset
)
```

- Velocity profiling: <10ms for 100-point trajectory
- Path blending: <50ms for typical blend zone
- Suitable for offline trajectory generation
---
## Integration with Existing RSIPI
Phase 4 methods integrate seamlessly with existing RSIPI functionality:
```python
# Generate complex trajectory with Phase 4
trajectory = api.motion.generate_circle(...)
# Apply velocity profile (Phase 4)
profiled = api.motion.generate_velocity_profile(trajectory, ...)
# Execute with existing Phase 1-3 methods
for waypoint, dt in profiled:
api.motion.update_cartesian(**waypoint) # Phase 1
time.sleep(dt)
# Or use convenience method
api.motion.execute_trajectory(trajectory, ...) # Phase 2
```
---

2. **Simple Coordinate Transforms**
- Chose translational + rotational offsets over full transformation matrices
- Sufficient for 90% of RSI applications
- Easier to understand and use
- Can be extended later if needed
3. **Static Methods in MotionAPI**
- Trajectory generation doesn't require API instance
- Can be used for offline planning
- Consistent with existing RSIPI architecture
4. **Cubic Hermite Spline for Blending**
- Zero velocity at endpoints ensures smooth transitions
- Simpler than quintic splines
- Sufficient for industrial applications
### Implementation Insights
1. **Edge Case Handling**
- Short trajectories need special handling in velocity profiling
- Blend radius must be validated against trajectory length
- Zero-radius cases need explicit checks
2. **Performance Trade-offs**
- More waypoints = smoother motion but longer generation time
- Typical industrial applications: 50-200 waypoints is optimal
- S-curve profiling is ~2x slower than trapezoidal but worth it
3. **Coordinate System Conventions**
- KUKA RSI uses right-handed coordinate systems
- Rotations follow KUKA's A, B, C convention
- Important to document frame assumptions clearly

# RSIPI: Robot Sensor Interface - Python Integration
# RSIPI: Robot Sensor Interface for Python
RSIPI is a high-performance, Python-based communication and control system designed for real-time interfacing with KUKA robots using the Robot Sensor Interface (RSI) protocol. It provides both a robust **API** for developers and a powerful **Command Line Interface (CLI)** for researchers and engineers who need to monitor, control, and analyse robotic movements in real time.
[![Python 3.10+](https://img.shields.io/badge/python-3.10+-blue.svg)](https://www.python.org/downloads/)
[![License: MIT](https://img.shields.io/badge/License-MIT-green.svg)](LICENSE)
RSIPI is a Python library for real-time control of KUKA industrial robots via the Robot Sensor Interface (RSI) protocol. The robot controller sends its state over UDP at a configurable cycle rate (4ms at 250Hz or 12ms at 83Hz), and RSIPI sends back position corrections, I/O commands, and Tech parameters. Communication uses XML packets over a dedicated Ethernet link, managed in a separate process so your control logic never blocks the real-time loop.
---
🛡️ Safety Notice
RSIPI is a powerful tool that directly interfaces with industrial robotic systems. Improper use can lead to dangerous movements, property damage, or personal injury.
## Safety Notice
⚠️ Safety Guidelines
Test in Simulation First
Always verify your RSI communication and trajectories using simulation tools before deploying to a live robot.
RSIPI directly controls industrial robot motion. Misuse can cause damage or injury.
Enable Emergency Stops
Ensure all safety hardware (E-Stop, fencing, light curtains) is active and functioning correctly.
Supervised Operation Only
Run RSIPI only in supervised environments with trained personnel present.
Limit Movement Ranges
Use KUKA Workspaces or software limits to constrain movement, especially when testing new code.
Use Logging for Debugging
Avoid debugging while RSI is active; instead, enable CSV logging and review logs post-run.
Secure Network Configuration
Ensure your RSI network is on a closed, isolated interface to avoid external interference or spoofing.
Never Rely on RSIPI for Safety
RSIPI is not a safety-rated system. Do not use it in applications where failure could result in harm.
## 📄 Description
RSIPI allows users to:
- Communicate with KUKA robots using the RSI XML-based protocol.
- Dynamically update control variables (TCP position, joint angles, I/O, external axes, etc.).
- Log and visualise robot movements.
- Analyse motion data and compare planned vs actual trajectories.
### Target Audience
- **Researchers** working on advanced robotic applications, control algorithms, and feedback systems.
- **Engineers** developing robotic workflows or automated processes.
- **Educators** using real robots in coursework or lab environments.
- **Students** learning about robot control systems and data-driven motion planning.
- **Test offline first** using the built-in echo server before connecting to a real robot.
- **Hardware E-stops** must be present and functional. RSIPI's software E-stop is not safety-rated.
- **Limit correction ranges** via `api.safety.set_limit()` and KUKA Workspaces.
- **Isolate the RSI network** -- use a dedicated Ethernet interface with no external access.
- **Never run unattended** without proper risk assessment and safety measures.
---

## 📃 Examples
## Quick Start
### Start RSI and update Cartesian coordinates
```python
api.start_rsi()
api.update_variable('RKorr.X', 100.0)
api.update_variable('RKorr.Y', 200.0)
api.update_variable('RKorr.Z', 300.0)
from RSIPI import RSIAPI
# Context manager handles cleanup on exit
with RSIAPI("RSI_EthernetConfig.xml") as api:
api.start()
if api.wait_for_connection(timeout=10.0):
# Send a 10mm correction in X
api.motion.update_cartesian(X=10.0)
# Read current TCP position
pose = api.motion.get_current_pose()
print(f"TCP: X={pose['X']}, Y={pose['Y']}, Z={pose['Z']}")
else:
print("No robot connection within 10s")
# api.stop() called automatically
```
### Retrieve joint positions
Without the context manager:
```python
a1 = api.get_variable('AIPos.A1')
api = RSIAPI("RSI_EthernetConfig.xml", rsi_mode="relative")
api.start()
api.wait_for_connection()
api.motion.update_cartesian(X=5.0, Y=-3.0)
api.stop()
```
### Plan and execute Cartesian trajectory
```python
start = {'X': 0, 'Y': 0, 'Z': 0, 'A': 0, 'B': 0, 'C': 0}
end = {'X': 100, 'Y': 100, 'Z': 0, 'A': 0, 'B': 0, 'C': 0}
traj = api.plan_linear_cartesian(start, end, steps=50)
api.execute_trajectory(traj)
---
## Configuration
RSIPI reads `RSI_EthernetConfig.xml` to determine network settings and which variables are exchanged with the robot.
```xml
<ROOT>
<CONFIG>
<IP_NUMBER>10.10.10.10</IP_NUMBER> <!-- External PC IP -->
<PORT>64000</PORT> <!-- UDP port -->
<SENTYPE>ImFree</SENTYPE> <!-- XML root element name -->
<ONLYSEND>FALSE</ONLYSEND> <!-- FALSE = bidirectional -->
</CONFIG>
<!-- SEND: What the robot sends TO us (read-only from Python) -->
<SEND>
<ELEMENTS>
<ELEMENT TAG="DEF_RIst" TYPE="DOUBLE" INDX="INTERNAL" /> <!-- TCP position -->
<ELEMENT TAG="DEF_RSol" TYPE="DOUBLE" INDX="INTERNAL" /> <!-- Commanded position -->
<ELEMENT TAG="DEF_Delay" TYPE="LONG" INDX="INTERNAL" /> <!-- Packet delay count -->
<ELEMENT TAG="Digout.o1" TYPE="BOOL" INDX="2" /> <!-- Digital output state -->
</ELEMENTS>
</SEND>
<!-- RECEIVE: What the robot receives FROM us (writable from Python) -->
<RECEIVE>
<ELEMENTS>
<ELEMENT TAG="RKorr.X" TYPE="DOUBLE" INDX="1" HOLDON="1" /> <!-- Cartesian correction -->
<ELEMENT TAG="RKorr.Y" TYPE="DOUBLE" INDX="2" HOLDON="1" />
<ELEMENT TAG="RKorr.Z" TYPE="DOUBLE" INDX="3" HOLDON="1" />
<ELEMENT TAG="RKorr.A" TYPE="DOUBLE" INDX="4" HOLDON="1" />
<ELEMENT TAG="RKorr.B" TYPE="DOUBLE" INDX="5" HOLDON="1" />
<ELEMENT TAG="RKorr.C" TYPE="DOUBLE" INDX="6" HOLDON="1" />
<ELEMENT TAG="DiO" TYPE="LONG" INDX="8" HOLDON="1" /> <!-- Digital I/O -->
</ELEMENTS>
</RECEIVE>
</ROOT>
```
### CLI Sample
Key points:
- `DEF_` prefixed tags are expanded internally (e.g., `DEF_RIst` becomes `RIst: {X, Y, Z, A, B, C}`).
- `HOLDON="1"` means the last value is held if no new value is sent.
- SEND variables are read via `api.monitoring`, RECEIVE variables are written via `api.motion`, `api.io`, etc.
- The config must match the RSI object configuration on the KUKA controller.

```
### `api.safety` -- Safety Management
```python
# Emergency stop (software-level, NOT safety-rated)
api.safety.stop()
api.safety.is_stopped() # True
# Reset E-stop
api.safety.reset()
# Configure correction limits
api.safety.set_limit("RKorr.X", -50.0, 50.0)

print(f"{var}: [{lo}, {hi}]")
# Full status
status = api.safety.status()
# {"emergency_stop": False, "safety_override": False, "limits": {...}}
# Override limits (use with extreme caution)
api.safety.override(True)
# ... calibration work ...
api.safety.override(False)
```
### `api.monitoring` -- Live Data
```python
# Comprehensive snapshot
data = api.monitoring.get_live_data()
# {"position": {X,Y,Z,A,B,C}, "velocity": {...}, "force": {...}, "ipoc": 123456}

for w in api.diagnostics.get_warnings():
print(f"Warning: {w}")
if api.diagnostics.check_watchdog():

# Or specify filename
api.logging.start("my_experiment.csv")
api.logging.is_active() # True
api.logging.stop()
```
Logs include British-format timestamps, all send/receive variables per cycle. Logging runs in a separate process to avoid interfering with the 4 ms control loop.
### `api.viz` -- Visualization

# Deviation from planned path
api.viz.plot_static("logs/actual.csv", "deviation", overlay_path="logs/planned.csv")
# Comprehensive multi-plot visualization
api.viz.visualize_csv_log("logs/test.csv")
api.viz.visualize_csv_log("logs/test.csv", export=True) # Save to disk
# Compare two runs

# Live plotting (runs in background thread)
api.viz.start_live_plot("3d", interval=100) # 100ms update
api.viz.change_live_plot_mode("position")
api.viz.stop_live_plot()
```
### `api.tools` -- Utilities
```python
# Low-level variable access
api.tools.update_variable("RKorr.X", 10.0)
api.tools.show_variables() # Print all available variables
api.tools.show_config() # Network settings + variable structure
api.tools.reset_variables() # Zero out corrections
# Reports and comparison
api.tools.generate_report("logs/test.csv", "pdf")
diffs = api.tools.compare_runs("run1.csv", "run2.csv")
```

## RSI Mode and Rate Limiting
### Absolute vs Relative Mode
The `rsi_mode` parameter must match what your KRL program uses with `RSI_MOVECORR()`:
| Mode | Behavior | Use Case |
|------|----------|----------|
| `"relative"` | Corrections are **added** to the programmed path each cycle. Sending `X=1.0` every cycle moves 1mm/cycle continuously. | Continuous adjustments, sensor feedback |
| `"absolute"` | Corrections specify **total offset** from programmed path. Sending `X=10.0` holds 10mm offset regardless of how many cycles. | Target position offsets |
### Cycle Time
KUKA RSI supports two cycle rates, configured on the robot controller side. RSIPI's network loop is reactive (it responds to whatever the robot sends), but the `cycle_time` parameter ensures diagnostics, health checks, and jitter warnings use the correct baseline:
```python
# 4ms cycle / 250Hz (default)
api = RSIAPI("RSI_EthernetConfig.xml", cycle_time=0.004)
# 12ms cycle / 83Hz
api = RSIAPI("RSI_EthernetConfig.xml", cycle_time=0.012)
```
| Cycle Time | Frequency | Use Case |
|------------|-----------|----------|
| `0.004` (4ms) | 250 Hz | High-frequency corrections, sensor feedback loops |
| `0.012` (12ms) | 83 Hz | Standard motion corrections, less demanding applications |
### Rate Limiting
Rate limiting caps the per-cycle change to prevent sudden jumps:
```python
api = RSIAPI(
"RSI_EthernetConfig.xml",
rsi_mode="relative",
max_cartesian_rate=0.5, # Max 0.5 mm per cycle
max_joint_rate=0.1, # Max 0.1 deg per cycle
cycle_time=0.004 # 4ms cycle
)
```
Set rates to `0.0` (default) to disable rate limiting. Clamping is applied in the network process right before the response is sent to the robot.
---
## Testing
### Echo Server
RSIPI includes an echo server that simulates a KUKA controller for offline development:
```bash
> start
> set RKorr.X 150

```
---
The echo server binds to the same UDP port as a real robot, sends XML state packets at 250 Hz, and accepts correction responses. Use it to test your control logic without hardware.
## 📤 Output & Logs
- CSV logs saved to `logs/` folder.
- Each log includes timestamp, sent and received values in individual columns.
- Graphs can be saved manually as PNG/PDF from the visualisation window.
### Running with pytest
---
## 🚀 Getting Started
1. Connect robot and PC via Ethernet.
2. Deploy KUKA RSI program with matching configuration.
3. Install dependencies:
```bash
pip install -r requirements.txt
pip install -e ".[dev]"
pytest
```
4. Run `main.py` and use CLI or import API in your Python program.
Test files go in the `tests/` directory. The project uses `src` layout with `pythonpath = ["src"]` configured in `pyproject.toml`.

KUKA Robot Controller
|
UDP/XML (4ms cycle)
|
NetworkProcess <- multiprocessing.Process, owns the socket
|
Manager().dict() <- shared send_variables / receive_variables
|
RSIClient <- orchestrator: config, safety, network
|
RSIAPI <- runs RSIClient in daemon thread
/ | \ \
motion io krl safety monitoring logging viz diagnostics tools
```
- **NetworkProcess** runs in a separate OS process. It receives XML from the robot, parses it into `send_variables` (what the robot tells us), and builds the response XML from `receive_variables` (what we tell the robot). IPOC synchronization (`IPOC + 4`) is handled automatically.
- **RSIClient** creates the `multiprocessing.Manager` dicts for cross-process variable sharing, initializes the `ConfigParser` and `SafetyManager`, and manages the network process lifecycle.
- **RSIAPI** wraps RSIClient in a daemon thread and exposes the namespaced sub-APIs (`motion`, `io`, `krl`, etc.).
The 4 ms cycle is driven by the robot controller, not by RSIPI. If a response is not sent within the cycle window, the robot uses the last held values (for `HOLDON="1"` variables) or drops to zero.

## Configuration Requirements
### RSI XML Configuration
Your `RSI_EthernetConfig.xml` must support Cartesian corrections:
**Cartesian Corrections (RKorr):**
```xml
<RECEIVE>
<XML>
<ELEMENT Tag=\"RKorr\" Type=\"DOUBLE\" Indizes=\"[1..6]\"/>
</XML>
</RECEIVE>
```
### Network Settings
Ensure your RSI network settings match:
```xml
<IP_NUMBER>192.168.1.100</IP_NUMBER> <!-- Your PC IP -->
<PORT>49152</PORT>
<SENTYPE>ImFree</SENTYPE>
```
## Running Examples
### Step 1: Verify RSI Configuration
```bash
# Check that your RSI_EthernetConfig.xml has required elements
grep -A 5 "RKorr" RSI_EthernetConfig.xml
```
### Step 2: Run Example
```bash
cd examples/advanced_motion
python 01_velocity_profiles.py --config ../../RSI_EthernetConfig.xml
```
### Step 3: Monitor Output
Examples log comprehensive information:
- Trajectory generation details
- Velocity profile characteristics
- Motion execution progress
- Application use cases
**Example Output**:
```

## API Reference
### Velocity Profiling
```python
# Generate trajectory with timing information
profiled_trajectory = api.motion.generate_velocity_profile(
trajectory=waypoints,
max_velocity=200.0, # mm/s
max_acceleration=500.0, # mm/s²
profile='trapezoidal' # or 's-curve'
)
# Execute with precise timing
for waypoint, dt in profiled_trajectory:
api.motion.update_cartesian(**waypoint)
time.sleep(dt)
```
**Profiles**:
- `'trapezoidal'`: Bang-bang acceleration, constant velocity cruise, fast point-to-point
- `'s-curve'`: Jerk-limited smooth acceleration, reduced vibration and stress
### Geometric Primitives
```python
# Circular arc
arc = api.motion.generate_arc(
center={"X": 100, "Y": 0, "Z": 500},
radius=50.0,
start_angle=0, # degrees
end_angle=90, # degrees
steps=50,
plane='XY' # or 'XZ', 'YZ'
)
# Full circle
circle = api.motion.generate_circle(
center={"X": 100, "Y": 0, "Z": 500},
radius=30.0,
steps=100,
plane='XY'
)
# Spiral (expanding or contracting)
spiral = api.motion.generate_spiral(
center={"X": 100, "Y": 0, "Z": 500},
start_radius=5.0,
end_radius=40.0,
pitch=10.0, # mm per revolution (positive=descending)
revolutions=3.0,
steps=150,
plane='XY',
axis='Z'
)
```
### Path Blending
```python
# Generate two trajectories
traj1 = api.motion.generate_trajectory(p0, p1, steps=50)
traj2 = api.motion.generate_trajectory(p1, p2, steps=50)
# Blend for smooth transition
blended = api.motion.blend_trajectories(
traj1=traj1,
traj2=traj2,
blend_radius=20.0, # Start blending 20mm before corner
blend_steps=20 # Number of interpolation points
)
# Execute smooth continuous motion
api.motion.execute_trajectory(blended, space='cartesian', rate=0.02)
```
### Coordinate Transformations
```python
# Define frame offset
work_offset = {
"X": 500.0,
"Y": -200.0,
"Z": 50.0,
"A": 0.0,
"B": 0.0,
"C": 15.0
}
# Transform single pose
pose_work = {"X": 100, "Y": 50, "Z": 30}
pose_base = api.motion.transform_coordinates(
pose=pose_work,
from_frame='WORK',
to_frame='BASE',
frame_offset=work_offset
)
# Transform entire trajectory
trajectory_base = []
for waypoint in trajectory_work:
transformed = api.motion.transform_coordinates(
waypoint, 'WORK', 'BASE', work_offset
)
trajectory_base.append(transformed)
```
**Supported Frames**:
- `'BASE'`: Robot base coordinate system
- `'WORLD'`: Global world coordinates
- `'TOOL'`: Tool center point (TCP) coordinates
- `'WORK'`: Work object (pallet/fixture) coordinates
- `'ROBROOT'`: Robot root system
## Customizing Examples
### Adjust Velocity Limits
```python
# Faster motion (use with caution)
profiled = api.motion.generate_velocity_profile(
trajectory,
max_velocity=500.0, # Increase speed
max_acceleration=1200.0, # Increase acceleration
profile='trapezoidal'
)
# Slower, more precise motion
profiled = api.motion.generate_velocity_profile(
trajectory,
max_velocity=50.0, # Reduce speed
max_acceleration=150.0, # Gentle acceleration
profile='s-curve'
)
```
### Modify Geometric Patterns
```python
# Larger spiral for bigger holes
spiral = api.motion.generate_spiral(
center={"X": 100, "Y": 0, "Z": 500},
start_radius=10.0, # Larger start
end_radius=80.0, # Larger end
pitch=15.0, # Deeper per revolution
revolutions=5.0, # More turns
steps=250, # More waypoints for smoothness
plane='XY',
axis='Z'
)
# Vertical circle (XZ plane)
circle_vertical = api.motion.generate_circle(
center={"X": 100, "Y": 0, "Z": 500},
radius=40.0,
steps=100,
plane='XZ' # Vertical circle
)
```
### Adjust Blend Radius
```python
# Tighter blend (closer to sharp corner)
blended_tight = api.motion.blend_trajectories(
traj1, traj2,
blend_radius=5.0, # Small radius
blend_steps=10
)
# Wide blend (very smooth, cuts corner more)
blended_wide = api.motion.blend_trajectories(
traj1, traj2,
blend_radius=50.0, # Large radius
blend_steps=30
)
```
## Troubleshooting
### "RSI Communication Error"
**Problem**: Cannot establish RSI connection
**Solutions**:
1. Verify robot controller is powered on and in correct mode
2. Check network connectivity (ping robot IP)
3. Verify RSI XML configuration file path
4. Ensure RSI is enabled on robot controller
5. Check firewall allows UDP port 49152
### Motion Limits Exceeded
**Problem**: Trajectory exceeds robot workspace or velocity limits
**Solutions**:
1. Reduce `max_velocity` parameter in velocity profiling
2. Reduce `max_acceleration` parameter
3. Check trajectory waypoints are within robot workspace
4. Verify coordinate transformations are correct
5. Add safety margin to trajectory boundaries
### Jerky Motion Despite S-Curve Profile
**Problem**: Motion not smooth even with S-curve velocity profile
**Solutions**:
1. Increase number of waypoints (`steps` parameter)
2. Reduce `max_acceleration` for gentler motion
3. Check RSI communication rate (should be ~250Hz)
4. Verify no network latency issues
5. Ensure trajectory waypoints are well-distributed
### Blend Zone Too Large
**Problem**: Blending cuts corners too much or exceeds trajectory bounds
**Solutions**:
1. Reduce `blend_radius` parameter
2. Increase trajectory length before attempting blend
3. Check that blend_radius < half of shortest trajectory segment
4. Use smaller `blend_steps` for tighter control
5. Consider using multiple smaller blend zones
### Coordinate Transform Incorrect
**Problem**: Transformed positions don't match expected values
**Solutions**:
1. Verify `frame_offset` values are correct
2. Check from_frame and to_frame parameters are correct
3. Ensure frame offset includes both position and orientation
4. Test with simple known transforms first
5. Visualize transformed trajectory before execution
### Velocity Profile Not Applied
**Problem**: Robot doesn't follow calculated velocity profile
**Solutions**:
1. Verify you're using the timing (`dt`) from profiled trajectory
2. Check `time.sleep(dt)` is actually being called
3. Ensure system has sufficient timing resolution
4. Monitor actual execution timing with logs
5. Consider system overhead in timing calculations
## Advanced Usage
### Combining Multiple Features
```python
# 1. Generate geometric primitive
spiral = api.motion.generate_spiral(...)
# 2. Transform to correct frame
spiral_base = [
api.motion.transform_coordinates(wp, 'WORK', 'BASE', offset)
for wp in spiral
]
# 3. Apply velocity profile
spiral_profiled = api.motion.generate_velocity_profile(
spiral_base,
max_velocity=100.0,
max_acceleration=300.0,
profile='s-curve'
)
# 4. Execute with precise timing
for waypoint, dt in spiral_profiled:
api.motion.update_cartesian(**waypoint)
time.sleep(dt)
```
### Dynamic Trajectory Modification
```python
# Start with base trajectory
trajectory = api.motion.generate_circle(...)
# Apply sensor correction at runtime
for waypoint in trajectory:
sensor_offset = get_sensor_reading()
corrected = api.motion.transform_coordinates(
waypoint,
'BASE', 'BASE',
frame_offset=sensor_offset
)
api.motion.update_cartesian(**corrected)
```
### Multi-Layer Patterns
```python
# Generate pattern at multiple Z heights
layers = []
for z in range(0, 50, 10): # Every 10mm
circle = api.motion.generate_circle(
center={"X": 100, "Y": 0, "Z": z},
radius=30.0,
steps=50,
plane='XY'
)
layers.extend(circle)
# Blend between layers
for i in range(len(layers) - 1):
segment = [layers[i], layers[i+1]]
# Execute segment...
```
## Performance Optimization
### Trajectory Generation
- Use appropriate `steps` parameter: More steps = smoother but slower generation
- Generate complex patterns once, reuse multiple times
- Consider pre-generating common patterns at startup
### Velocity Profiling
- Trapezoidal profile is faster to compute than S-curve
- Use S-curve only where smoothness is critical
- Cache profiled trajectories for repeated operations
### Coordinate Transformations
- Transform entire trajectory once, not waypoint-by-waypoint in real-time
- Pre-calculate frame offsets before motion execution
- Use simple translational offsets when possible (faster than full 6-DOF)
### Path Blending
- Larger `blend_steps` = smoother but slower generation
- Balance blend_radius vs trajectory accuracy requirements
- Consider blending offline for repeated paths
## Next Steps
1. **Run basic examples** (01, 02) to understand individual features
2. **Experiment with parameters** to see their effects
3. **Combine features** using example 05 as a template
4. **Adapt to your application** specific requirements
5. **Integrate with sensors** for adaptive motion control

```bash
python 01_basic_handshake.py --config path/to/RSI_EthernetConfig.xml
```
**Flow**:
1. Start Python script
2. Execute KRL program on teach pendant
3. Python waits for KRL ready signal
4. Python performs processing
5. Python signals completion
6. KRL continues with motion
**API Features Demonstrated**:

- `api.krl.signal_complete(channel)`
---
### 02_parameter_passing.py
**Bidirectional parameter exchange**
Demonstrates numerical data exchange using RSI Tech variables.
**Requires**: `templates/krl/parameter_passing.src` running on robot
**Run**:
```bash
python 02_parameter_passing.py --config path/to/RSI_EthernetConfig.xml
```
**Flow**:
1. KRL writes current position to Tech.T variables
2. Python reads position data
3. Python calculates target position
4. Python writes target to Tech.C variables
5. Python signals completion
6. KRL reads target and executes motion
**API Features Demonstrated**:

**Requires**: `templates/krl/state_machine.src` running on robot
**Run**:
```bash
python 03_state_machine.py --config path/to/RSI_EthernetConfig.xml
```
**Flow**:
1. Python monitors state variable (Tech.T11)
2. Calibration state: Python performs calibration routine
3. Python writes calibration offsets to Tech.C
4. Executing state: KRL uses offsets for motion
5. Complete state: Workflow finishes successfully

- 9: ERROR - Error condition
**API Features Demonstrated**:
- All coordination methods from examples 01 and 02
- State monitoring loop
- Error handling with I/O signals
- Real-time state transitions
---
## Configuration Requirements
### RSI XML Configuration
Your `RSI_EthernetConfig.xml` must include the following elements:
**Digital I/O:**
```xml
<SEND>
<XML>
<ELEMENT Tag="Digin" Type="INT"/>
</XML>
</SEND>
<RECEIVE>
<XML>
<ELEMENT Tag="Digout" Type="INT"/>
</XML>
</RECEIVE>
```
**Tech Variables:**
```xml
<SEND>
<XML>
<ELEMENT Tag="Tech" Type="DOUBLE" Indizes="[1..199]"/>
</XML>
</SEND>
<RECEIVE>
<XML>
<ELEMENT Tag="Tech" Type="DOUBLE" Indizes="[1..199]"/>
</XML>
</RECEIVE>
```
### Network Settings
Ensure your RSI network settings match:
```xml
<IP_NUMBER>192.168.1.100</IP_NUMBER> <!-- Your PC IP -->
<PORT>49152</PORT>
<SENTYPE>ImFree</SENTYPE>
```
## Running Examples
### Step 1: Start Python Script
```bash
# In one terminal
cd examples/coordination
python 01_basic_handshake.py --config ../../RSI_EthernetConfig.xml
```
### Step 2: Execute KRL Program
1. Upload corresponding KRL program to robot controller
2. Switch to AUTO mode on teach pendant
3. Select and execute the KRL program
4. Monitor coordination in Python terminal
### Step 3: Monitor Output
Python will log:
- State transitions
- I/O signal changes
- Parameter reads/writes
- Errors and warnings
**Example Output**:
```
2026-01-17 14:32:01 - INFO - Starting RSI communication...
2026-01-17 14:32:01 - INFO - ✅ RSI started successfully
2026-01-17 14:32:01 - INFO - Waiting for KRL ready signal...
2026-01-17 14:32:05 - INFO - ✅ KRL signaled ready!
2026-01-17 14:32:05 - INFO - Performing Python-side processing...
2026-01-17 14:32:07 - INFO - ✅ Processing complete
2026-01-17 14:32:07 - INFO - ✅ Signaled KRL to continue
```
## Customizing Examples
### Modify Processing Logic
In `01_basic_handshake.py`:
```python
# Replace simulated processing
time.sleep(2.0)
# With actual processing
sensor_data = read_sensor()
processed_result = analyze_data(sensor_data)
update_database(processed_result)
```
### Change Calculation Logic
In `02_parameter_passing.py`:
```python
# Modify target calculation
target_x = current_x + 100.0 # Original
target_x = calculate_adaptive_target(current_x, sensor_feedback) # Custom
```
### Extend State Machine
In `03_state_machine.py`:
```python
# Add new states
class State(IntEnum):
IDLE = 0
CALIBRATING = 1
INSPECTING = 2 # NEW STATE
READY = 3 # Renumber subsequent states
# ...
# Handle new state
elif current_state == State.INSPECTING:
inspection_result = perform_inspection()
api.krl.write_param('C20', inspection_result)
api.krl.signal_complete(1)
```
## Troubleshooting
### "Timeout waiting for KRL signal"
**Problem**: Python doesn't receive expected I/O signal from KRL
**Solutions**:
1. Verify KRL program is running on robot
2. Check I/O configuration in RSI XML
3. Verify network connectivity (ping robot IP)
4. Check signal mapping ($OUT[1] → Digout.o1)
5. Increase timeout: `api.krl.wait_for_signal(1, timeout=60.0)`
### "RSIVariableError: Tech.T11 not found"
**Problem**: Tech variable not in receive_variables
**Solutions**:
1. Add Tech variables to RSI XML `<RECEIVE>` section
2. Restart robot controller after XML changes
3. Verify variable configuration: `api.tools.show_variables()`
### "Connection refused"
**Problem**: Cannot connect to robot controller
**Solutions**:
1. Check robot IP address in RSI XML
2. Verify robot is in correct mode (T1/T2/AUTO)
3. Ensure firewall allows UDP port 49152
4. Check RSI is enabled on robot controller
### KRL Program Halts
**Problem**: KRL program stops unexpectedly
**Solutions**:
1. Check KRL timeout values (increase if needed)
2. Verify Python script is running before KRL execution
3. Check error signals ($IN[2] for error condition)
4. Review KRL logs on teach pendant
## Advanced Usage
### Non-Blocking Monitoring
For continuous operation without blocking:
```python
import threading
def monitor_state():
while running:
state = api.krl.read_param('T11')
if state == CRITICAL_STATE:
handle_critical_state()
time.sleep(0.1)
# Run monitoring in background thread
monitor_thread = threading.Thread(target=monitor_state, daemon=True)
monitor_thread.start()
# Main thread does other work
perform_other_tasks()
```
### Multiple Coordination Channels
Use different I/O channels for parallel coordination:
```python
# Channel 1: Main workflow
if api.krl.wait_for_signal(1):
api.krl.signal_complete(1)
# Channel 2: Emergency stop
if api.io.get_input(2): # Emergency input
logging.error("Emergency stop!")
api.safety.stop()
# Channel 3: Auxiliary signaling
api.io.pulse(3, duration=0.1) # Quick pulse signal
```
### Integration with Motion Control
Combine coordination with real-time RSI corrections:
```python
# Wait for motion start
api.krl.wait_for_signal(1)
# Send real-time corrections during KRL motion
for i in range(100):
sensor_offset = get_sensor_offset()
api.motion.update_cartesian(X=sensor_offset)
time.sleep(0.004) # 250Hz
# Signal motion complete
api.krl.signal_complete(1)
```
## Next Steps
1. **Test examples** with your robot controller
2. **Adapt templates** to your specific application
3. **Implement error recovery** mechanisms
4. **Create custom workflows** for your use case
5. **Document coordination** protocols for your team

License: GNU AFFERO GENERAL PUBLIC LICENSE
Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The GNU Affero General Public License is a free, copyleft license for software and other kinds of works, specifically designed to ensure cooperation with the community in the case of network server software.
The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, our General Public Licenses are intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
Developers that use our General Public Licenses protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License which gives you legal permission to copy, distribute and/or modify the software.
A secondary benefit of defending all users' freedom is that improvements made in alternate versions of the program, if they receive widespread use, become available for other developers to incorporate. Many developers of free software are heartened and encouraged by the resulting cooperation. However, in the case of software used on network servers, this result may fail to come about. The GNU General Public License permits making a modified version and letting the public access it on a server without ever releasing its source code to the public.
The GNU Affero General Public License is designed specifically to ensure that, in such cases, the modified source code becomes available to the community. It requires the operator of a network server to provide the source code of the modified version running there to the users of that server. Therefore, public use of a modified version, on a publicly accessible server, gives the public access to the source code of the modified version.
An older license, called the Affero General Public License and published by Affero, was designed to accomplish similar goals. This is a different license, not a version of the Affero GPL, but Affero has released a new version of the Affero GPL which permits relicensing under this license.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU Affero General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based on the Program.
To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
The Corresponding Source for a work in source code form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
13. Remote Network Interaction; Use with the GNU General Public License.
Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version by providing access to the Corresponding Source from a network server at no charge, through some standard or customary means of facilitating copying of software. This Corresponding Source shall include the Corresponding Source for any work covered by version 3 of the GNU General Public License that is incorporated pursuant to the following paragraph.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the work with which it is combined will remain governed by version 3 of the GNU General Public License.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU Affero General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU Affero General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU Affero General Public License, you may choose any version ever published by the Free Software Foundation.
If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
RSI-PI
Copyright (C) 2025 adam
This program is free software: you can redistribute it and/or modify it under the terms of the GNU Affero General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more details.
You should have received a copy of the GNU Affero General Public License along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If your software can interact with users remotely through a computer network, you should also make sure that it provides a way for users to get its source. For example, if your program is a web application, its interface could display a "Source" link that leads users to an archive of the code. There are many ways you could offer source, and different solutions will be better for different programs; see section 13 for the specific requirements.
You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU AGPL, see <http://www.gnu.org/licenses/>.

# RSIPI: Robot Sensor Interface - Python Integration
RSIPI is a high-performance, Python-based communication and control system designed for real-time interfacing with KUKA robots using the Robot Sensor Interface (RSI) protocol. It provides both a robust **API** for developers and a powerful **Command Line Interface (CLI)** for researchers and engineers who need to monitor, control, and analyse robotic movements in real time.
---
🛡️ Safety Notice
RSIPI is a powerful tool that directly interfaces with industrial robotic systems. Improper use can lead to dangerous movements, property damage, or personal injury.
⚠️ Safety Guidelines
- **Test in Simulation First:** Always verify your RSI communication and trajectories using simulation tools before deploying to a live robot.
- **Enable Emergency Stops:** Ensure all safety hardware (E-Stop, fencing, light curtains) is active and functioning correctly.
- **Supervised Operation Only:** Run RSIPI only in supervised environments with trained personnel present.
- **Limit Movement Ranges:** Use KUKA Workspaces or software limits to constrain movement, especially when testing new code.
- **Use Logging for Debugging:** Avoid debugging while RSI is active; instead, enable CSV logging and review logs post-run.
- **Secure Network Configuration:** Ensure your RSI network is on a closed, isolated interface to avoid external interference or spoofing.
- **Never Rely on RSIPI for Safety:** RSIPI is not a safety-rated system. Do not use it in applications where failure could result in harm.
---
## 📄 Description
RSIPI allows users to:
- Communicate with KUKA robots using the RSI XML-based protocol.
- Dynamically update control variables (TCP position, joint angles, I/O, external axes, etc.).
- Log and visualise robot movements with live graphs and static plots.
- Analyse motion data and compare planned vs actual trajectories.
- Parse and inject RSI into KRL programs.
- Simulate robot behaviour using a realistic Echo Server.
- Enforce safety limits and manage emergency stops.
### Target Audience
- **Researchers** working on advanced robotic applications, control algorithms, and feedback systems.
- **Engineers** developing robotic workflows or automated processes.
- **Educators** using real robots in coursework or lab environments.
- **Students** learning about robot control systems and data-driven motion planning.
---

Returns:
True if signal received, False if timeout occurred
Example:

... print("KRL signaled ready!")

... else:

>>> api.motion.update_cartesian(X=100) # Send correction
>>> api.krl.wait_for_signal(1) # Wait for KRL to acknowledge
>>> # KRL has processed the correction, safe to continue
Note:
This is a blocking operation. The check_interval determines polling
frequency - lower values provide faster response but higher CPU usage.
For typical RSI applications, 10-50ms intervals are appropriate.
Warning:
Ensure the KRL program actually sets the signal, otherwise this will
block until timeout. Consider using try/except for timeout handling.
