Looking at putting 2 one-Farad capacitors on the robot.

Is this legal?
Are you actually observing a significant instantaneous voltage drop? If so, you need to check your main power connections to be sure they are solid. If not, don't worry about it, the batteries themselves are very good at sourcing large instantaneous currents.

As for your cap idea, I'm afraid it is illegal, although awesome.

Custom high impedance voltage monitoring or low impedance current monitoring circuitry connected to the ROBOT’S electrical system is acceptable, because the effect on the ROBOT outputs should be inconsequential.
