I've now heard of another team at WPI where the robot eas only able to spin in circles. Can someone from the drive team give details as to when it started during the match, what you were able to do, what eventually happened, etc?

I looked for footage but couldn't locate either. I was able to investigate one of these right after it happened, and expected it to be a chain, jammed, a speed controller, etc. I found a missing limit jumper on a jag that would have disabled one motor in one direction, but it wasn't clear that this was the issue, contributed to it, or was there all season and they were simply driving with a severely imbalanced drivetrain. They had four motors.

Before I explain what I suspect, I'd like to hear about recent issues involving spinning robots that weren't due to mechanical or speed controller issues.
