Recently, 2 of our motors on our x drive have died out; when we turn on the device tab brain, the died-out motors aren’t there in the corresponding spot, and it just shows an empty slot even when the motor is attached. This was fixed by replacing motors, but this has been happening consistently. My friend brought the motors home and told us that it was the circuits that broke, not the motors. Our drivetrain also slows down eventually after 3 - 5 minutes of drive. I’m not sure if this is related to the problem, but I’d say that this is definitely also uncommon as our robot isn’t really all that heavy.
Any ideas on how to prevent this from happening?
