What would really be cool is: 2 arm robots and a launcher. The arm robots capture the trackballs and load the launcher. Launcher fires, arm robot who just loaded it scurries under the overpass and grabs the ball, taking it around again. Meanwhile, the other arm robot comes in to reload the launcher. At the end of the game, the arm robots put the trackballs up, and the launcher crosses the finish line.
