[RoboMaster]

I don't think that this was the cause to our problem, but one time our robot was unable to drive around during the whole match. The wheels would move and other motors on our robot would move just fine and such, but apparently our back two wheels (we had 4WD for our traction control) were not moving. Our front wheels were not able to provide enough pulling force to move our robot and we could only inch forward.
This doesn't sound like a symptom of this problem, but just wanted to throw that out there. Our robot is mysteriously fine now and we have theorized till our brains cramped.
