Shooter consistency

Betcha you could put a piece of reflective tape on your belt and use a IR proximity sensor on that. Don't get too attached on putting the sensor on some rotating thing, yeah?

As for the voltage control on a CAN Jaguar, that's better than nothing, not as good as actual feedback control. It will compensate somewhat for state of charge differences in your battery. It won't compensate for the spin down from firing a frisbee and it's going to deal poorly with rapid voltage changes from, say, your drivetrain or some other system making voltage fluctuate. Feedback is really the best way to go for getting fast, consistent shooting.
