We have a GoPiGo3 with a Raspberry pi 2, and it has been working for weeks up until a couple days ago. We’ve encountered a problem where the right motor will rotate faster when commanded, and it won’t stop rotating, even when we quit terminal. The only way to turn it off is to restart the robot. The motor is making louder noises than usual. Replacing batteries did not solve the problem, but make it worse by making the right motor turn faster and be louder. The problem has occurred in each program we have run.
