For their last lab session, thirteen four-person teams competed with one another using software they developed to control a robot to putt golf balls at three different holes during a three-minute time period. The irregular course included sand traps, a wa ter hazard, and a "little people" audience. Once the correct program for all three holes was determined the robot took over on "auto mode" and consistently sunk ball after ball into the holes. The incentive for the exercise was extra credit for the high-s coring teams.
