Wheel speed is monitored, but control is open loop for now. Balls exit at around 65 degrees (fixed angle). Azimuth is controlled with the chassis - no turret. Camera assist for aiming. The bottom wheel runs wide open, and the top is throttled to maximize backspin and control distance.

I hope Dave doesn't see these. He'll want you to put in a banana and use it for a game clue. - IndySam [more]
