This was my senior design project at Caltech. Our team constructed 3 robots with a budget of just $1.5k for a “robot soccer” competition, in which teams had several minutes to score as many goals as possible. The game had 12 balls, three goals on each side, and obstacles in the center of the field. We used chain and sprocket drive train, fabricating all sprockets from stock with a waterjet. While we did not win the competition, our robots were so powerful that the instructor required we add bumpers, lest we damage the playing field.
