Re: Robot doesn't turn in high gear

Team 418 used a 6 wheel drive, 4 small CIM-DeWalt transmission drive train. We lowered the center wheels 3/32", which is enough to sink the center wheels in the carpet, but still have all 6 wheels contact the ground. In 2nd gear we realized we had some difficulty turning (the RC was resetting, I believe), and after talking with the electronic guys we think we figured out why. When designing the drive train, I figured we could run each small CIM at 40 amps (since they are on a 40 amp breaker); however, I was informed that the power distribution block is rated for 85 amps (I'm not exactly sure, but around this number). This means we weren't getting the current, and thus the torque, we had planned on. Perhaps you guys are facing a similar problem.
