Unable to run multi-robot simulation demo

I have run the multi-robot simulation demo following the instructions. All of the things runs smoothly but the robot could not move as planned(as shown in the picture). It seems like that some part of the navigation algorithm didn’t initialize successfully. Does anybody know how to solve the problem? thx

I have the same issue. In my case, Robot 1 sometimes moves successfully but Robot 2 doesn’t move at all when following the instructions in the tutorial. Have you been able to resolve this problem?
