Two wheels of Pioneer_3DX were broken in simulationby Ken Chen (1) 2019-01-08 12:00:46
My Webots version is R2019a.

Hello , I set a Pioneer_3DX robot to follow walls by learning in many iterations , and my controller was installed supervisor for impacting the wall to reset the initial position normally.
But I found that when number of reset times become larger, then the two wheels are Separated.
In this picture , the iteration was 75 . And training mode is selected to "fastest mode".

I guessed that ... maybe I need to choose the more slowly mode? But I'm still not sure what the real reason is.

Is there any method could solve this problem?

Hi Ken,

It might happens that small errors accumulate at each iteration, a more robust approach would be to reload the simulation from your supervisor controller.
Please have a look here for more information:
