Suggestion
Tim Skloss,
Great design, could I add one suggestion? I know the circuit breakers are designed to trip in .1 seconds once the current reaches 40 amps, but in case of a catestropic failure it could exceed that amount for a very short time. In the unlikely event something happens we've added a 5.1 V zener to the output of our sensors as protection for the RC analog inputs.
We actually take our measurements at the outputs of the speed controller and I think our circuit works... we'll know how well as soon as they allow us time to wire the robot.
Best of luck!
