Teams that don't build a little adjustment into this system can run into other problems as teams found out at Champs. When the subsurface floor is neither flat nor smooth, some adjustment should made to the drop wheels in order to get the desired performance. At Champs, the plastic underlayment sagged in the middle. Since the underlayment was a four foot square, robots in the 38" dimension sometimes had difficulty in turns when in the center of a square. Also, if you cannot quickly change wheels, adjustment may allow you to compensate for tread wear on the dropped wheels.
