Re: 6 CIM Drive Train

One of the specific questions we have is whether you've had any problems with drastic voltage drops when going from a standstill to full throttle? Or going from full speed to a forced stop i.e. hitting another bot/entering pushing match? Has it effected anything else i.e. radio power?

Any feedback would be great, thanks everyone!
A person on my team played around with one on the off season, and he said it was a pretty good experience. He said that if you geared the robot for a moderate top speed, acceleration was very quick, and was very maneuverable. He also had some power draw issues. Full forward to full reverse caused the main robot breaker to trip, and that one doesn't reset, so the robot would be dead until somebody hit the switch again.

They solved this by ramping the motors (see here), and when they switched to 2 CIMs plus a miniCIM on each side, they couldn't get the breaker to trip.
