Shooter consistency

Transmission used belts, and the wheels we were given are Aluminum (so no magnetic sensor), and an encoder mount is impossible without redesigning the entire gearbox. We also used pneumatic tires with a custom machined rim (so no holes to track with an optical sensor). Unless we attached a magnet to the wheel and used a hall effect sensor below it... but that would destabilize the already fairly shaky wheel unless we used a *tiny* magnet.

Paint the wheel black and then attach a piece of reflective tape and use an optical sensor.
