Bouncy Ball Collecting Robot

As a part of the UCSD MAE 3 Robotics Competition, my team and I were challenged to design and fabricate a robot that could score bouncy balls into different goals within 1 minute. 

I came up with a simple yet effective design to lift, twist, and drive each ball into the goal worth the most points.  

Our robot would go on to beat out more than thirty other teams to win first place in the Spring 2011 Robotics Competition.
