This IS a real mechanism, but is not neccesarily mounted on a robot. The top of the 'device' was 60" off the ground. It uses a single 7" wheel spinning at ~1750rpm. The balls exit the device at around 35 degrees. It would shoot faster if we had a method of feeding them faster.
Please remember, I could have easily posted this in the robot showcase forum but instead chose to post this in the rumor mill!!
