Seconded. Both of 1293's robots thus far have used casters on one side or another. In 2005, it didn't matter much (mainly because our autonomous was drop the arm, drive forward about 12.93 inches, and knock the hanging tetra off).
In 2004, however, making sure our casters were perfectly straight became essential to the proper performance of Bob's autonomous mode. (Whether it actually knocked off the ball, however, is another story.
