Major Updates Regarding the Future of the Small Size League
by Nicolai Ommer 31 Jul '25

31 Jul '25

Dear SSL RoboCup Teams, There are major upcoming changes to RoboCup Soccer that affect the SSL and its members. What is Happening? To start, the trustees are taking substantial action to streamline RoboCup Soccer in pursuit of the 2050 goal of playing a match against the World Cup winner. The first and most substantial change is that all soccer leagues will be converging on humanoid (bipedal) robots by 2028. The new leagues will be related to humanoid robotics and simulation only. The Small Size League will no longer be a major category event after the 2027 RoboCup (the SSL will be at the 2027 event, and not at the 2028 event and after). This is true for many of the other leagues, and there will be substantial changes to the humanoid rules and non-soccer events as well. The official press release from the RoboCup federation can be found here: https://www.robocup.org/news/181 The SSL community has several transition paths forward. We understand each team is unique, and will have team specific concerns. We have two major paths forward right now: SSL regional events, possibly with Junior collaboration, and transition to humanoid league. We have explicitly been told by the trustees we are invited to continue our league under the RoboCup name at regional events after 2027. Our community already has several strong regional events including the German Open, RoboCup Brazil, and the Japan Open. The EC/TC/OC believes we have strong support from the organizers of these regionals, though work will need to be done to transition to and support these events if additional teams attend. The committee is evaluating ways to keep the international community together, like by selecting one regional per year, after 2027, as a “super regional” that would rotate among the current regional events similar to the international event. The trustees have also begun a transition plan for teams who would like to switch to one of the humanoid leagues and remain on the world event stage. For teams looking to transition quickly, the trustees are working to get discounts and collaborative use of commercial bipedal robot platforms. We will communicate additional details about the humanoid rules and transition assistance as it becomes available. Expect additional communication directly from the governing bodies of global RoboCup. We may also have an opportunity to convert the SSL to a simplified bridging league in Junior, with the intention of creating a pipeline of students from RoboCup Junior, through the SSL, into humanoid. If this succeeds, we will likely still hold regional events, but then will also have a presence on the world stage in some form, though not in the major event category. This is an evolution of the collaboration games we have been hosting with Junior for the past few years. The committees are working hard to quickly determine what this will look like. We understand these are big changes and they may come as a surprise to all of you. The committee members only just found out about the new direction during this year's RoboCup, as the overall desires of the RoboCup trustees became more clear. What to expect in the coming months. Obviously, things will be changing. The committees will be hosting a meeting for teams that could not attend the competition, and for teams that would like to meet with us again. This meeting will take place on August 9th. We will announce the time soon. It will cover the same content that was covered in the Open TC/OC meeting in Brazil. We will have time for questions at the end. After, expect a series of short surveys about transition paths and team concerns. This will help us support you, regardless of what path makes sense for your team. Second, expect technical challenges and other requests from the committee to look differently. The things we ask you to do may shift focus to better support strong regionals. The committees have always and will always support our community and teams. It has been amazing getting to know each and every one of you. You and your teams make our SSL community special. We have over two years to develop our plans and make sure teams are healthy. We are working hard for you. Feel free to email us directly with specific concerns or questions, even though we may not have answers right now. We are committed to clear and timely communication as new information becomes available. We look forward to seeing everyone in South Korea for next year’s major event! Best Regards, SSL EC/TC/OC Nicolai Ommer Tobias Heineken Leonardo da Silva Costa Emiel Steerneman Joao Guilherme Oliveira Carvalho de Melo William Stuckey David Brand Emy Ganzeboom Lucas Cavalcanti

Open OC/TC Meeting Road Map and Slide Deck
by Will Stuckey 16 Jul '25

16 Jul '25

Hello Everyone, As part of the open OC/TC meeting, we usually discuss the future of the league. The OC and TC have prepared a draft of a 5 year roadmap and have also prepared a slide deck (which we may not be able to present) summarizing a plan we have to take the league forward. This is a guide for discussion, not a final document. We would like feedback at the OC/TC meeting. For any team who would like to give extended feedback, we also welcome replies to this email. As detailed in the documents, we have identified three possible major thrusts for improvement: 1. Improving the new and young team experience 2. Improving motion control through benchmarking 3. Exploring and integrating novel AI Links included Road Map Document: https://docs.google.com/document/d/1CkvQC72z7nOF-CXU_ZERyf2YjiO2FxNZG9BaXuB… Summary Slide Deck: https://docs.google.com/presentation/d/1OiC37CqpEBelR_R5LyKga_e_RLm2oHcN/ed… We look forward to hearing your thoughts at the meeting and via email.

RC 2025 one week out
by David Brand 09 Jul '25

09 Jul '25

Hello, Since the competition is one week from now, we want to send you another update Radio Information Request Please fill out the radio information survey so we know what radio technologies your team is using. This will let us allocate you a frequency and deconflict teams and the venue. The link is: https://forms.gle/eyNMYQga9B4DdseU8 Technical Challenges This year we will be hosting two technical challenges. The [team vs. team passing challenge](https://robocup-ssl.github.io/technical-challenge-rules/2025-ssl-team-vs-team-passing-challenge.html) with an updated ranking system open for teams from both divisions. On top of that, we will have a new [obstacle avoidance challenge](https://robocup-ssl.github.io/technical-challenge-rules/2025-ssl-obstacle-avoidance-challenge.html), which is only open for Div B teams. If you want to participate in at least one challenge please submit your intent via the corresponding [form](https://forms.gle/sd6ADCTkkcYU6DuY6) until July 15th, 20:00 o’clock BRT(Salvador local time). Award Voting Like last year we will be doing the voting this year via online forms. As we especially wanted to give you more time to evaluate the Open Source Submissions as well as the (E)TDPs, we also already set up the voting forms for both of them: - [Open Source Ballots](https://forms.gle/ktxk2gXsWgGgEQfM8) - [Best (E)TDP](https://forms.gle/yZEzGtcZLzgySHQ57) But as in the previous years the voting will only be due during the RoboCup as the Open Source Presentation is an essential part of the award. Also as last year you will be getting a unique team code, so that malicious votes can be eliminated. In case you already want to look at the questions beforehand, feel free to use “test” as team name as well as the unique code, which allows us to easily delete these votes. Referee Quiz As a quick reminder from the last mail, every team participating in the RoboCup2025 needs to be able to fill out their assigned impartial roles for matches, when they do not play. These members have to take the [referee quiz](https://forms.gle/8frZcLYPx5o3KVF29) beforehand. In case you have any open questions or any trouble during your travel, please let the OC/TC know as soon as possible. This allows us to see whether we can help you in any way. See you in Salvador! David, on behalf of the SSL committee

RoboCup 2025 – Open Source Award Submission The A-Team
by Matt 02 Jul '25

02 Jul '25

Hello league-mates, This year, The A-Team would like to submit ssl_ros_bridge for the Open Source Award. https://github.com/SSL-A-Team/ssl_ros_bridge ssl_ros_bridge is a small collection of ROS2 utilities to help teams using ROS connect to SSL league software interfaces. It provides bridge nodes which manage network connections to ssl-vision and ssl-game-controller, exposing ROS topics and services mirroring the protobuf packets used by the league software. We hope this open source software will especially help new teams get started with SSL software without having to learn our league's network protocols in detail. It is offered as its own repository to make including it in other team's software easier. Thank you for your consideration, ~Matthew Barulic The A-Team
