Can the do anything special? Such as, unless I'm crazy, it looks as though you would be able to move the robot in any direction without having to first turn the robot. For example, if both back wheels spun clockwise and the two front wheels spun counterclockwise, the robot could move sideways. (Just a crazy idea)

WPI had a fully holomonic drive base last year using mecanum wheels.

Do you have some kind of sensor that will communicate actual distance traveled by each wheel back to the RC. The mecanum wheel drive train works on the principle of force vectors (you can each wheels direction and force to come up with your net force, therefore your net acceleration) I would think dropping some velocity on a wheel would cause this thing to behave quite erratically.
