533 amps is 4 small CIM motors in a stall condition (133A each). Not to mention 2 bike motors, 2 FP motors, et cetera...

I predict that many robots will peak at over 800A during the competition. As Dave Lavery said at the kickoff, there will be "meltdowns"...

JMHO,

You're probably right; we only had 2-wheel drive last year, so the wheels would spin far before stall condition. I still wonder, though, about the 40 amp breakers and the main 120 amp breaker? Wouldn't they prevent the 800-amp meltdown?

Probably the best configuration would be a diode type splitter such that power would always be drawn from the stronger source.

The best part is, since the camera is "custom circuitry", the above would be legal under the rules!
