RoboCup 2026 Small Size League Rule Update
by Emiel Steerneman 13 Apr '26

13 Apr '26

Dear SSL community, *Rule change* I would like to bring your attention to a change in the SSL rulebook <https://robocup-ssl.github.io/ssl-rules/sslrules.html>. A new substitution area has been created behind the goals on Div A fields. This is done by extending the width of the area behind the goals from 0.3 meters to 0.6 meters. The new rule can be found in section 9.1.1 Goal Substitution Area (Division A only) <https://robocup-ssl.github.io/ssl-rules/sslrules.html#goal-substitution-area> *A robot is considered to be in the Goal Substitution Area if it is at least 0.3 meters outside the field, behind its own goal line. Robots are allowed to remain in the Goal Substitution Area while the game is running. They are allowed to move freely and must comply with the following rules:* - *Minimum ball distance during stop or free kick* - *Must not interfere with ball placement* Additionally, the following line has been added to section 3.1 Number Of Robots <https://robocup-ssl.github.io/ssl-rules/sslrules.html#_number_of_robots> *Robots in the Goal Substitution Area do not count towards this limit.* *Protobuf message* Following the rule change, the protobuf message messages_robocup_ssl_geometry.proto has been updated with two new fields: *boundary_width_goal_line* and *goal_substitution_area_width. * *Autorefs, GC* The GameController and the TIGERs autoref have been updated in accordance to this rule change. All latest changes to this year's rulebook can always be found at https://robocup-ssl.github.io/ssl-rules/sslrules-diff.html Best regards, Emiel Steerneman - TC

RC2026: Registration Open
by David Brand 31 Mar '26

31 Mar '26

Hello, RoboCup is getting closer every day and the registration system is finally open. All teams that have successfully claimed a slot already and are in the list of the Committed Teams should have received a CVENT invite by now and therefore be able to register their team. Due to issues in the recent years, the person assigned as team leader must also be joining as a participant during the event. In case that will not be the case and you would like to change the team leader, please reach out to the OC mailing list, so that we can make the appropriate changes. Please give us the info before you start with the registration of the team and its members as it is much easier to give you a new invitation slot instead of changing an existing one. If your team is competing for the first time at an international RoboCup event, be aware that there are First Time Fee Waivers. These will eliminate the need to pay the team registration fee (member fees usually still apply), but neither the team, nor a single team member can have previously taken part in an international event. If you think you are eligible, please get in contact with the OC, so that we can guide you through the process. Registration Timeline: Early Registration: until May 4th Regular Registration: May 5th - Jun 2 Late Registration: Jun 3 - Jun 16 (additional members only - no new teams) Pricing & Visa letters: More info about the pricing, visa letters and more can be found on the CVENT page and its subpages. Please do not get irritated, the competition will take place in Incheon, but due to a lot of things being the same as last year, there are still some traces from Brazil present. [RC2026 - CVENT page](https://web.cvent.com/event/4f86f2fa-cfac-446d-aa11-c1f712e4ece8/webs… Please have in mind that in case your team is conditionally qualified or if you would like to update your (E)TDP, the Final Submission Deadline to submit updated material is March 31st AoE (so in about 17 hours). In case you have already submitted your material and have not yet heard back from us yet, thanks a lot, we are currently in the process of checking it and will get back to you as soon as possible. In case of any open questions or issues, please do not hesitate to contact any committee member. Looking forward to seeing you in Incheon, David. ------------ RoboCup Small Size League | OC Member

2026 Qualification Video - TritonBots [Updated]
by IEEE Robocup 26 Mar '26

26 Mar '26

Dear RoboCup SSL Organization Committee, Please see below for a link to the updated TritonBots qualification video: https://drive.google.com/file/d/1-YEir2M9gfh_JQpTkpyLwJVkLbbGRoAe/view?usp=… . In addition to adding cooperative play against obstacles, we updated our video to showcase our most recent offensive and goalkeeping strategies. We improved the previous strategies to achieve more competitive results. If the video is inadequate for full qualification, we would really appreciate knowing early so that we may try to film an adequate version. However, our team is on spring break until March 29, so no one may be on campus to refilm until then. Thank you! Sincerely, Raymond Rada and Lukas Cao robocup(a)ieeeatucsd.org

Re: Preliminary Results and Slot Allocation
by David Brand 24 Mar '26

24 Mar '26

Hello, We hope you are all well and that preparations for the RoboCup are going according to plan. We are sorry for the delay on our end, but unfortunately it has taken us much longer to get back to you, than expected. This year, we decided to verify the quality of all the reviews, which made the review process much more time-consuming. During that process, we came across a few reviews that we did not feel comfortable sharing with the reviewed team. Since these reviews did not meet the standards we want to see in this community and would have been painful for the teams—who spent their free time on the project—to read, we have decided to redact them. This is the first time this has happened, so it took us some time to reach this decision. In response to that, we will also be issuing an updated guidance and policy for next year. We apologize if your team is affected by this decision and now has only two reviews. To publish the remaining reviews as soon as possible, unfortunately, we were unable to provide alternatives. If you have questions about the two reviews your team received, please contact any committee member, and we will try to help. You should have received the reviews for your team within the last hour now that the decisions have been made. Since the Final TDP submission deadline is in a couple of hours, we have decided to reschedule it to March 31 AoE. This means you have an additional week to submit an updated (E)TDP or video. We hope this is enough time for anyone who wants to improve their (E)TDP. In case you already submitted updated materials, please be patient, we will be looking into them in the next few days and get back to you. The deadline to accept an offered slot remains unaffected. If you were offered a slot in the first phase and can commit to joining us in Incheon, please send us your letter of commitment by March 31 AoE. More information about the slot process and your team's current slot status can be found here: [Qualification Slot Process](https://ssl.robocup.org/robocups/robocup-2026/robocup-2026-qualifi… [Slot Status](https://docs.google.com/spreadsheets/u/0/d/1E3hFgMjvlyj9cwQWjiQdw8w… In case of any questions or issues, please do not hesitate to contact any committee member. Thank you for your patience, David. On behalf of all SSL OC/TC/EC members

Preliminary Results and Slot Allocation
by David Brand 11 Mar '26

11 Mar '26

Hello! Going through all participation materials is sadly taking a bit longer this year. Nonetheless most teams should have received a mail regarding their preliminary qualification status by now. In case you are missing a mail and are not already in contact with us, feel free to contact us as well. This delay also means that we cannot send out the reviews yet, as we still need to wait until all reviews are finished. In addition, there is some general information that we would like to share. As previously mentioned, we will be using a slot system again this year. More information can be found on the following homepage: [2026 Qualification Slot Process](https://ssl.robocup.org/robocups/robocup-2026/robocup-2026-qualifi… To claim an allocated slot, please fill out the Letter of Commitment template by the appointed deadline. You can use the [2026 Slot Status](https://docs.google.com/spreadsheets/d/1E3hFgMjvlyj9cwQWjiQdw8wdj7N… sheet in combination with your appointed team ID to see the status of your team in the qualification process. To see the qualification status of all teams, visit the [2026 Teams homepage](https://ssl.robocup.org/robocups/robocup-2026/robocup-2026-teams/), which will be updated throughout the process. The number of slots may increase if local circumstances allow. If teams cannot compete at RoboCup 2026 but still want to attend, we may be able to offer observer tickets, which allow access to the venue and team area to experience the competition. This is intended for new teams that struggle to qualify. If you can come, we would be very happy to see you experience RoboCup and our community. If you are interested, please indicate this in a reply so that we can have a better overview of how many teams are interested. If you have any questions, please do not hesitate to contact the OC/TC/EC. Thank you, David Brand. ------------ RoboCup Small Size League | OC Member
