I have the same topic but I do not get the answer and try it again. In component testing, when performing 'move base 90 degrees' and perform scan, pi suddenly does not execute and shut down and reboot itself. In particular, when performing a perform scan, there is a break in the phrase "waiting for calibration routine and motor speed to stabilize". What should I do? Anyone who can help with this matter would be greatly appreciated if you could help. Please.
