Thank you very much both for your help. I am not sure what caused the problem, but it is solved. I calibrated the motors, rebuilt the robot and it worked ? I haven’t done it yet because I started building the robot before I downloaded the app and when it asked me it was too late ? Yo were very kind.

Hello. I am building Charlie with the new Lego 51515 set and I am having problems with the drumset activity. One of the arms doesn’t work ok. I know that it it is because I haven’t set properly the 0 positions of the engines, but I don’t know how to solve it. I tried to improve it a lot of times but it’s impossible for me. The head of the robot stay always a bit to the left. Can anyone help me?
