RoboCup Early Visa Invitation Letters
by 2024＠robocup.org 21 Jan '24

21 Jan '24

Dear RoboCuppers, We are very much looking forward to inviting all of you to Eindhoven, The Netherlands for RoboCup 2024! To allow more teams to join RoboCup 2024, we offer early visa invitation letters. Participants that require a visa to join RoboCup in The Netherlands may apply for an early visa invitation letter. This letter allows for making an earlier appointment at an embassy to request a visa, rather than only after completing registration. There are some constraints on who can receive a visa invitation letter. You can find the details, as well as the request form, on the RoboCup 2024 website: https://2024.robocup.org/?page_id=2998 We hope to see you at RoboCup 2024! Best regards, RoboCup 2024 Organisation 2024(a)robocup.org <mailto:2024@robocup.org>

Changes for the Small Size League in 2024
by Tobias Heineken 16 Jan '24

16 Jan '24

Happy New Year! As we start the preparations for RoboCup 2024, we would like to inform the league of the main upcoming changes for this year's competition, based on the discussions from the last Open OC/TC meeting at the end of RoboCup Bordeaux. We also want to give the league a quick heads-up that the Team Qualification Material Submission deadline for this year's RoboCup is February 13th. The CMT for submitting the (E)TDPs is now open and more information can be found at the qualification website <https://ssl.robocup.org/robocup-2024-qualification/>. The (Updated) Qualification process Starting with RoboCup 2024, the SSL will limit the number of teams participating in the competition. With the expected field setup, this limit is 12 teams in Division B and 8 in Division A. If more space becomes available, more slots in Division B will open up. To determine the selected teams, the TC/OC will rank all based on their qualification video, initial TDP submissionand feedback given during the review process. The TDP will generally be given preference over the qualification video & review feedback. For Division A, the 8 slots available will be decided using the ranking system cited above. If not all slots of Div A are filled, the TC/OC will invite teams from Division B until all slots are used. For Division B, there will be 8 slots that will be filled using the ranking system and 4 slots that will be filled randomly. This will ensure that new teams will have a chance of participating in the competition. All teams that did not get a slot in Division A are considered for Division B. Qualified teams that are not invited according to this method end up on the waiting list, which again is sorted based on the ranking described above. The TC/OC will inform a team “You’re on the waiting list, your position is #2”. If a slot opens up, we will contact the teams in that order to find a team that is still interested in coming to the RoboCup. This is additional to the “qualified / conditionally qualified” system we are currently using. The requirements for (E)TDPs and Qualification Video will also not change. Remember that teams regularly drop out (“withdrawn”) or don’t get qualified (“not qualified”), so there is a realistic chance a team on the waiting list can get invited. If you are directly qualified and not on the waiting list, please notify TC/OC immediatelyif you wish to withdraw so we can start communicating with teams on the waiting list. Number of robots for Division A In Bordeaux, the number of robots for division A was 11 and only two teams managed to actually play with 11 robots. With that in mind, and also wanting to provide more opportunities for teams in Division B to join Division A, we are making modifications to the allowed number of robots in Div A. During thegroup phase, games will be played with 8 robots on each side unless both teams agree to play with 11. And during the knockout phase, all games will be played with 11 robots per team.We still want to incentivize teams to play with 11 robots, but we do understand that this can be hard, especially for teams coming from Division B. Rule changes One major upcoming rule change is regarding the robot substitution process. Currently, a robot substitution is almost free, and a team can use almost unlimited time to do such a substitution. In RoboCup Japan (2017) we started the automatic robot substitutions <https://robocup-ssl.github.io/ssl-rules/sslrules.html#_robot_substitution>, but in its current implementation, flagging a robot substitution has no consequences.This can lead to diverting the focus of the development from obtaining stable hardware, and can cause excessive downtime during gameplay. The rule change imposes some consequence to performing a robot substitution. We have not concluded our discussions, but are considering the following options (or a combination of these): * A time limit on the robot substitution (either similar to the timeouts, or individually for each substitution event) * Limiting the number of substitutions * Consequences after a certain amount of substitutions o Examples include losing a timeout, getting a yellow card, a free kick, etc. Please stay attentive to our emails for any more announcements of rule changes. Technical challenges We have planned some exciting technical challenges for this year! The details are not ready yet, but we would like to give an overview so teams can start preparing for them. Black & White Hulls We have received a lot of feedback that for the audience, it is hard to distinguish between teams since most teams use black hulls. Therefore, we are proposing a challenge in which teams will have to show how they will quickly change their hulls’ colors between black and white. Team vs. Team Passing Challenge We want to extend last year’s passing challenge to involve other teams! This year, the passing challenge will involve two teams, each one trying to pass the ball to themselves. We are excited to see some ball stealing action and what strategies teams come up for this! Please direct all inquiries to the Small Size League Organizing Committee: rc-ssl-oc(a)lists.robocup.org <mailto:rc-ssl-oc@lists.robocup.org> Thank you!

RoboCup 2023 – Open Source Award Submission RobôCIn
by José Victor Silva Cruz 05 Jul '23

05 Jul '23

Hi, everyone! We are proud to announce a series of repositories that we plan to submit at this year's open-source. Hopefully they will help grow our category here at RoboCup. RobôCIn's Plans for Future Software Development *rSoccer*: https://github.com/robocin/rSoccer - Is an open-source framework to study Reinforcement Learning for SSL; - Related Documents: - Exploring Reinforcement Learning in Path Planning for Omnidirectional Robot Soccer - https://www.cin.ufpe.br/~tg/2022-2/tg_EC/TG_jvsc.pdf - DyLam: A dynamic reward weighting method for reinforcement learning policy gradient algorithms: - https://repositorio.ufpe.br/handle/123456789/46630 - Evaluation of time limits in reinforcement learning applied to robot soccer simulation - https://www.cin.ufpe.br/~tg/2020-2/TG_EC/tg_jnds.pdf *project-unification*: https://github.com/robocin/project-unification This project aims to demonstrate the use of the soccer-common framework ( https://github.com/robocin/soccer-common), developed by RobôCIn and used in the RoboCup SSL and IEEE VSS categories. Also, the repository serves as a starting point to the team’s new developers and teams that want to start strategies on SSL. Usage examples: - MatheusPaixaoG: https://github.com/MatheusPaixaoG/project-unification - matheuslafayette: https://github.com/matheuslafayette/projeto-seletivo-robocin - agaf2: https://github.com/agaf2/project-unification - acrucha: https://github.com/acrucha/project-unification - caiomvfc: https://github.com/caiovmfc/Seletiva-RoboCin-VSS-cvmfc *robocin-cpp:* https://github.com/robocin/robocin-cpp - It is a library heavily inspired by abseil owned by Google, and seeks to extract what worked well from soccer-common, implementing software engineering best practices and modern C++ with a README-by-folder based documentation. It provides the core library for our next team's robotics applications. - Floating-point comparison; - Angular/geometric operations; - In the long term it will be like libsrc in 2D for our team. *protocols:* https://github.com/robocin/protocols The protobufs used by the competition are widely dispersed in the repositories that require them, making it necessary to copy and paste the files that are currently being used in the category. Thus, the protocols used are highly duplicated in the RoboCup SSL softwares, but also in the team’s strategy softwares. In this context, we propose a single repository containing the protocols used by as well as installation guidelines for various programming languages, such as Java, C++, Python, etc. *robocin-ines:* https://github.com/joseviccruz/robocin-ines, https://github.com/uandersonricardo/robocin-ines-server, https://github.com/uandersonricardo/robocin-ines-webui robocin-ines provides a base framework for architecting robotic applications. This set of repositories comes as an optimization of our current software (ssl-unification), providing a microservices-based framework which: 1. Enables the use of different programming languages; 2. Uses the ZeroMQ framework to communicate services with latency below 1ms; 3. Defines a visualization on the Web, providing better development simplicity; However, this final structure is not yet finalized and, as a way to validate the technologies, scope, and robustness of the system, the SSL VAR was developed as an MVP of this repository. SSL VAR is a match recording system, which allows the viewing of the match in real time, as well as the analysis of past plays through replay at a given timestamp or according to a given event in the match, such as a foul, penalty, or goal. In this way, it allows the human referee to analyze a past play and check whether his decision and also the decisions of the automatic referees were correct or not. The ultimate goal of this repository is to provide a base structure for organizing new SSL teams using microservices, and to extend the life and maintenance of our current software. Best regards, RobôCIn.

RoboCup 2023 - Open Source Award Submission RoboFEI
by João Victor Aguiar 04 Jul '23

04 Jul '23

Dear SSL community, RoboFEI would like to submit our hardware and software works for the open-source award. We are happy to say that we have released all the mechanics, electronics, AI, and firmware for this year. Regarding mechanics, the new robot's generation is fully released on our GitLab (https://gitlab.com/robofei/ssl/ssl-mechanics). The project aims for modularization that will help robot maintenance and assembly. In electronics, both the main and kick boards have been changed aiming for modularization, besides the fact that the team replaced the FPGA with an STM microcontroller to modernize our robot, and you can see everything here in the link (https://gitlab.com/robofei/ssl/Electronics_v2). Besides that, our new firmware is released on our GitLab too ( https://gitlab.com/robofei/ssl/Electronics_v2). About the software, our ongoing research of multi-robot path-planning is fully released on our GitLab (https://gitlab.com/leo_costa/RobotNavigation). Best regards, João Victor RoboFEI
