Over the summer Team 223 Xtreme Heat held a week long robotics camp in which we built a base for a robot. It has two powered wheels in the rear and a trackball (an old bowling ball) in the front. It is steered via tank steering. The plan was to turn it into a robot to help collect the paper recycling boxes for the school's recycling program run by the Nature Club. Due to time constraints, only the base was completed. It is very fast and turns on a dime.
