Change in design

We had a setback last week. The ball shooter stressed the gear motors. I guess the warning not to drive the small gear with a large gear on the motor was more than just a "guideline". The last two meetings we recovered well. we went back to a couple variations of designs we had earlier centering on a catapult.

From Isaac's Little Lost Robot

This is the mechanism to tension the catapult.
