RoboCupJunior SoccerSim Demo 2022

The RoboCupJunior Soccer Sim Demo competition is exactly what it sounds like: a chance to try out the Webots-based Soccer Sim environment, along with the new updates prepared for 2022. These include:

The "Demo" in its name refers to the fact that it is not an "official" competition but rather sort of a trial for the official competition that will be held in July 2022.


The rules are based on the regular RoboCupJunior Soccer rules, adapted to the simulation environment.

You can find them at

Note: The rules haven't changed much from the last year. Perhaps the most important change is the change of the world's coordinate system. We encourage you to check out the sample Robot controllers as well as the Webots documentation.


Just as in 2021, we'll use a Webots world adapted to our rules and will accept controllers programmed in Python 3. The latest version of the environment can be found on the link below. We consider the code done for the Demo 2022 competition, meaning no significant changes are expected, just bug fixes.

Check it out and let us know what you think!


We now have two fully fledged documentation articles that can help you get started programming your robots:

If you feel like there is something missing in the documentation, do not hesitate to suggest a change -- Pull Requests are very much welcome!
