Correction results and open OC/TC meeting
by Selina Zwerver 11 Jul '21

11 Jul '21

Hi everyone, It has come to our attention that we made a mistake in the calculation of the final ranking in the hardware challenges. A corrected version has now been published on the website <https://ssl.robocup.org/robocup-2021-results/>. We are very sorry for this. Open OC/TC Meeting We will host our annual Open OC/TC meeting on Sunday July 11th, at 15.00 GMT to discuss anything related to SSL and this year’s competition. Please remember to jot down your discussion topics on this document <https://docs.google.com/document/d/1MMUPNaxnxabsZ1xzSWxMVwDUt4Kznjy9qhzeQUW…>, which we will use as a base to create the agenda for the meeting. Reminder: Feedback Please remember to fill out this form <https://docs.google.com/forms/d/e/1FAIpQLSdcb_-6CX0CfHhPhiJKtQyqBDSK4vXjf94…> regarding feedback of the competition this year. It was a different style and we would like to know what went well and what did not. Some points of interest might later become topics in the Open OC/TC Meeting. If you have any questions about the new results or the meeting, please contact us. Kind regards, Selina Zwerver RoboCup Small Size League | Organizing Committee

RoboCup 2021 – Open Source Award Submission RoboFEI
by Bruno Bollos 23 Jun '21

23 Jun '21

Dear SSL community, Since the end of 2020, we have been releasing a good number of repositories as open source software. We are doing it for two main reasons. Firstly, we believe on the give-a-penny-take-a-pennyconcept. Based on this principle, since we are daily using lots of open source software developed by the Small Size League Community, we should also share our software in a sign of gratitude, in a way of contributing to the community have always supported us. Secondly, we believe that sharing software is important for educational purposes, we have learned a lot from open source software (like how to rewrite and reuse a piece of software) and we hope that, releasing our software to the public, we can help others in that way too. Sharing software is equivalent to sharing knowledge, which is beneficial for everyone. Below you will find our publications on the last year: Software (SSL-Strategy) Link: <https://gitlab.com/robofei/ssl/SSL-Strategy> Languages:C++ (almost 99% of the source code); Python; QMake This is the software that we use during RoboCup matches. Its main purpose is to control one team during a Small Size League game. The GUI is highly customizable (with options like selecting number of defenders and offenders, the maximum speed of the robots, the maximum strength of a kick and so on). It has a nice graphical client for visualizing the field and some options, like the interaction with the simulator. The source code and the interface are all in Brazilian Portuguese idiom, so it might be difficult to use it for non-Portuguese speakers. Nevertheless, we are planning to add an English translation to the software; that way, the GUI could be used in both, English and Portuguese languages. Software (LogAnalyserRoboFEI-SSL) Link: <https://gitlab.com/robofei/ssl/LogAnalyserRoboFei-SSL> Languages:C++; QMake This software is based on the Robocup Small Size League C++ Log Tools (https://github.com/RoboCup-SSL/ssl-logtools) and on the RoboFEI Small Size League Main Software (https://gitlab.com/robofei/ssl/SSL-Strategy). It provides a simple log player combined with a graphical client can that read vision and referee messages (from the network or directly from the log player). Furthermore it provides more options for loading and playing a match log file; for example, it is possible to ignore the match states when the game is stopped or halted and consider the other states. The Kalman filter from our main software is also embedded with the application. Other additional functionalities like, download the Match League Log Files directly from the software and the use of predefined shortcuts provides an easy environment for the user watch Small Size League matches recorded or in real time. At last, the Enable Analysis option activates a feature that can check when a shoot move or pass move occurs and evaluates this move in a 0 to 250 scale. At the end, a file is generated with the results. We are working on an implementation that provides a game statistics viewer tool that shows statistics of the game (like the ball possession, the amount of passes and pass precision, shoots to goal and so on), but it is still in development. Software (JoystickRobotController): Link: <https://gitlab.com/robofei/ssl/joystickrobotcontroller> Languages:C++; QMake The objective of this software is to easily test the RoboFEI robots – verifying if the robots wheels, kick sensor, dribbler, and other components are working properly. It makes it possible to control the robot, either with a joystick controller or with a computer keyboard. Sincerely, The RoboFEI team.

Robot Specs
by Carla Cosenza 22 Jun '21

22 Jun '21

Dear SSL Teams, There have been some complaints about the acceleration and max_speed in the simulation. While we intended to model the fact that we all have real robots and all robots are different, we noticed that the accelerations and speeds are not what we expected. Some teams that performed very well in terms of acceleration and speed during the last physical RoboCup in Sydney seem to be ending up at the slow side in this year's simulation. This could be due to improper specification regarding the kind of acceleration we meant (perfect conditions or something you can reach reliably), or teams could have copied others if they had no idea how to get these values or weren't able to go to their lab to determine them. Furthermore, we as the TC/OC might be to blame for not coming up with a good scalable way of checking the values you submitted, and teams preferring overestimating themselves over underestimating. Whatever it might be, the TC/OC decided that we will switch to a common acceleration profile, starting from the lucky losers and knockout matches. The common accelerations will be the average of all submitted specs, i.e: acc_speedup_absolute_max: 4.7, acc_speedup_angular_max: 50.8, acc_break_absolute_max: 5.9, acc_break_angular_max: 51.6, vel_absolute_max: 3.7, vel_angular_max: 26.2 We apologize for the inconvenience.

RoboCup 2021 - Open Source Award Submission ER-Force
by Paul Bergmann 22 Jun '21

22 Jun '21

Dear SSL community, as in past years, we are happy to submit our entry for the Open Source Award. You will find a list of our publications below. Framework + Simulator: This is the main software we use to develop and test our AI. It is able to - simulate this year's SSL games - control robots - create game recordings and play them back ...and much more. The repository also contains our simulator, bundled as a standalone executable for usage in this years RoboCup. https://github.com/robotics-erlangen/framework Autoref This is our automatic referee, that detects the various rule infringements teams can commit during a SSL game. https://github.com/robotics-erlangen/autoref In case you have questions about our software or are just curious, feel welcome to write an email to info(a)robotics-erlangen.de Best regards ER-Force -- Robotics Erlangen e.V.
