Hi, my kit is Ultimate 2.0 10-1 robot kit with MegaPi. I’ve built it according to video instructions and as soon as I turn it on the weels start to spin and the robot goes forward but never on 90 degrees, always by dragging itself on the floor.
The behavior is shown in the following video: https://www.youtube.com/watch?v=rDJk3WjSYpQ
I’ve already upgraded the firmware but same results
