RoboCup 2025 - Open Source Award Submission TIGERs Mannheim
by Felix Weinmann 20 Jun '25

20 Jun '25

Dear Small Size League, we are proud to present our 2025 open source award submission: The vision processor! https://github.com/TIGERs-Mannheim/vision-processor The vision processor aims to be a drop-in replacement for SSL-Vision. The shape based blob detector and decentralized software architecture is intended to minimize setup time and improve detection rates in uneven illumination conditions. Since the initial announcement on the SSL Discord 5 months ago, multiple tournaments have been completed using vision processor exclusively. Tigertastic greetings, TIGERs Mannheim

RC2025: Junior Demo Matches
by David Brand 16 Jun '25

16 Jun '25

Hello! After the matches last year between TIGERs on behalf of the SSL and the Junior Soccer LightWeight and Open Leagues received positive attention and feedback, we want to host the matches this year again, deepening our cooperation to further increase knowledge transfer between both leagues. Since the junior teams will consist of robots from multiple teams again, we want to prove that the SSL can play with robots from multiple teams on a shared team as well. After a first test during the German Open ([Lifestream of the match](https://www.youtube.com/live/__ASDKObXNY?si=B_cGATAb3sl5xPfe&t=3087)), where TIGERs and ER-Force gave their best to split the responsibility on the field, we want to expand the circle of competing teams. Therefore we are currently looking for teams that are open to the challenge and would like to join the matches. As the junior bots are usually a bit more fragile than the SSL bots, all competing robots must be limited to the following values: - Max Robot speed: 2.0 - Max Robot acceleration: 2.0 - Max Ball speed: 2.5 In addition to that, the use of chip kicks is strictly forbidden.Disabling the chip kicks in hardware is strongly encouraged and preferred, but disabling it in software is also fine. To ensure that these limits are not violated, each SSL team will have to demonstrate compliance to these limits beforehand. The matches will take place on the main Div B field. Therefore, the ruleset used will be similar to the SSL Div B ruleset. As all junior bots will get equipped with vision patterns, and the GC will control the SSL bots and coordinate the matches. Expect some adaptations to improve the flow of the game by the refs or GCO, you should not need to adapt your AI or hardware beyond the safety limitations. Since the schedules of the involved leagues are still being finalized, we do not have a specific time for the demo yet. However, I expect it to take place on Friday or Saturday. Since we will need the main Div B field anyway, there is no need to worry about scheduling conflicts with other matches. However, since tournaments never run as expected, you can always withdraw from the challenge. If you have any questions regarding the matches or would like to join the matches feel free to reach out to the OC. Thanks, David. ------------ RoboCup Small Size League | OC Member

RC2025 Cargo Shipment
by David Brand 12 Jun '25

12 Jun '25

Hi, We want to forward the request from the Local Organization: The company responsible for Cargo is talking with Brazilian customs to solve all the procedures to receive the team's payloads as quickly as possible. To accelerate this process, they are asking teams who contacted them to prove their registration to RoboCup 2025. In case you plan to ship your robots beforehand and already contacted the cargo company, please follow the request. In case you won't use the shipment option, but rather take the robots with you, you can ignore the request. Thanks, David. ------------ RoboCup Small Size League | OC Member

Awards and new Open Source Award deadline
by David Brand 14 May '25

14 May '25

Hello! As in the previous years, the awards for this year can be found on this years homepage: [RC 2025 - Awards](https://ssl.robocup.org/robocups/robocup-2025/robocup-2025-awards/) Like last year we will have the Excellence Award again, although the exact point system for this year is currently still in the works and going to be published in the next few weeks. New Open Source Award Submission Deadline: The submission deadline for this year's Open Source award is now 2 weeks before the start of the tournament and therefore July 01st(AoE). The submissions must still be sent to the [SSL Mailing List](robocup-small(a)lists.robocup.org), with the subject RoboCup 2025 - Open Source Award Submission <Your Team Name>. During the submission phase, we are going to collect all of them on the [Open Source Submission page](https://ssl.robocup.org/robocups/robocup-2025/robocup-2025-open-sourc…. After the submission deadline we are going to publish the voting ballots, so that each team can already start with the evaluation of the submissions. The presentation of the submissions as well as the voting deadline will still be during the RoboCup, so that everyone still has the possibility to discuss each submission and the submitting team is able to answer open questions in person. If you have any questions regarding the awards or this year's processes, please feel free to reach out to the SSL OC and TC. Thank you, David. ------------ RoboCup Small Size League | OC Member

Registration Process RC2025
by David Brand 27 Apr '25

27 Apr '25

Hello, As many have perhaps already seen, the invitation mails for the registration have already been sent out. In case that your team has not received an email and has expected one, please reach out to the [SSL OC](rc-ssl-oc(a)lists.robocup.org) and we will look into it and get back to you as soon as possible. If you need to withdraw from the competition, please decline the Invitation via the button in the email and send the OC an email as well, since we are not sure whether we will be notified of the declined invitations and need to adapt the tournament schedule. Regarding the registration schedule, the deadline for the early registration is May 16th and the regular registration ends on June 13. After that comes the Late registration until June 30, in which you cannot register teams any longer and only can add additional team members. The confirmation for the paid registration as announced in the preliminary qualification email, is not needed any longer, since we were able to offer each qualified team a slot at the tournament. Nonetheless, it would be great to get notices about withdrawals rather soon, since changes to team numbers could have a rather big impact on the tournament structure and schedule. If you need an invitation letter for your visa, these will only be sent out, after you registered your team. Therefore, especially for the teams needing a visa, please register as soon as possible, so that you have enough time to acquire the needed visa. In case you want to know, whether you need a visa or not, have a look at the following document written by our three LOCs this year: https://silly-snowman-187.notion.site/Tips-for-RoboCup-2025-1760464cbae080c… In there you can also find additional information to the [RoboCup 2025](https://2025.robocup.org/) homepage regarding import regulations, accommodations and much more. In case you have any additional questions, feel free to contact the OC or our three LOC members [Pedro Pizzaro](pedro.gpizarro(a)gmail.com), [Joao Victor Aguiar](jv628911(a)gmail.com), [Joao Guilherme Oliveira Carvalho de Melo](jgocm(a)cin.ufpe.br) directly. Thank you, David (on behalf of the SSL Committees)

Technical challenges
by Carla Cosenza 13 Apr '25

13 Apr '25

Hello! We are sorry about the delayed announcement of the technical challenges. We were trying to finish our goals and long term roadmap in order to align them but did not manage to. Due to that, we have opted for continuing one of the challenges from last year and having a DivB only challenge. Passing challenge The passing challenge from last year will be repeated. This year's rules will be the same as last year and can be found at https://robocup-ssl.github.io/technical-challenge-rules/2024-ssl-teams-vs-t…. The only difference this year will be the ranking system. In short, a team's ranking will not be determined by the total amount of passes made over all matches. It will be determined by relative strength over the opposing teams. A more detailed motivation and explanation can be found here https://github.com/emielsteerneman/passing_challenge_scoring. For any questions regarding this technical challenge, please reach out to TC member Emiel Steerneman. Obstacle avoidance challenge - DivB only 2025 is going to feature a DivB only technical challenge focussed on avoiding obstacles. To make sure that teams with faster robots do not win by default, the speed of the robots is limited to stop speed. Detailed rules are to come, but the most important points are below. * A team will control one robot at stop speed (1.5 m/s), with the objective to quickly reach the destination without touching the obstacles. * Obstacles can either be static, or also slow moving obstacles (significantly slower than the 1.5 m/s stop speed). * Expect robot-shaped, line-shaped or triangle-shaped obstacles. * The challenge will take place on half a div-B field. * To avoid pre-calculating the shortest path, the exact scenarios will be kept secret until shortly before the challenge takes place. * There will be multiple trials per scenario, and touching an obstacle ends a trial [so touching an obstacle has to be avoided at all cost]. * A (not used) example scenario will be published in May. Thank you Carla Cosenza RoboCup Small Size League | Organizing Committee

Preliminary Results and Slot Allocation
by Carla Cosenza 18 Mar '25

18 Mar '25

Hello! We are happy to announce that we have finished going over peer reviews and have submitted the preliminary qualification results. Each team should have received an email from an OC member with their results and we will soon publish them on our website. We also are happy with the overall quality of the TDPs and ETDPs we have seen this year! Regarding which teams have been granted slots in this year's RoboCup, all teams should know their slot situation from their qualification email. Slots have been assigned regardless of qualification status, however teams that have been conditionally qualified and fail to resubmit improved materials will lose their slots on or before April 15th. As stated in previous emails, we have allocated 4 slots in Division B for random selection, in order to guarantee the participation of new teams. The four randomly selected teams were: Sysmic Robotics, TritonBots FC, TurtleRabbit and Project Neon. For teams that have qualified and have been given a slot, we will send out registration codes as soon as possible. Starting from that date, teams will have 4 weeks to send us confirmation of the team registration payment. Failure to do so will result in the team losing its slot and a team on the waitlist being called to fill that spot. If your team is aware that you will not be able to make it, please reach out to the Organizing Committee as soon as possible so that we can call another team. After that, every team that is contacted because a slot has been open will have 3 weeks to provide the confirmation of the team registration payment. We are aware that this will add complexity to the qualification process but we do have more teams wanting to join than are physically possible in the venue. We will do our best to communicate with everyone and expect your collaboration too. Thank you, Carla Cosenza RoboCup Small Size League | Organizing Committee
