Soccer Simulation Demo 2021 - Issues and questions

Dear teams,

We need your help to test some changes in the simulator. Please, check out this thread:

[WE NEED YOUR HELP] Soccer Simulation - Inter-robot communication

Hello everyone! We have implemented inter-robot communication feature – this required us to contribute to the Webots itself because we needed to do some small adjustments there. However, Webots plans to release next official version in June/July, so if you would like to have inter-robot communication available during RoboCupJunior in June, we need to test nightly build, whether everything works as before with official release. In order to achieve that, we need you, the participants, to help us…

Thanks!
Felipe.

Hello @adrianmatejov

@adrianmatejov

3. Yeah, when robots are not moving, the ball moves just a bit. I’ll play with it and try to fix it if possible, but at first it looks like a Webots issue.

For question 3, we found a workaround, the patch file is located at

@Leo Thanks. Could you please create a pull request with your fix to our repository?

However, this is still a workaround and I’ll most probably create an issue in Webots repository.

@adrianmatejov I have created a pull request on the repository with the fix.

Hi,

My team has found an interesting and funny ending scene when one of their simulation finished:

Since this was just the finishing scene of a simulation, we only can assume that until a replacement to a neutral spot would not happen for any other reason, the traveling robot probably would be trapped on the top of the other robot (having a nice panoramic overview of the field and conserving some fuel though ). This issue seems to be extremely rare (has only occurred once that we managed to notice), so probably the issue’s severity is quite low.

Anyway, as a nice to have bug fix solution, maybe the referee.utils is_outside(x, z) should be extended by a 3rd dimension? Like is_outside(x, z, y)?

Best regards,
Robert

Thanks @rlaszlo, that’s a very nice bug report!

It seems we won’t make it to a hotfix but we’ll try to clean it up after the craziness of the June competition passes.

Thanks again!
