Whoops!

Thanks for correcting me, I'm still learning. :)

Our Universal Chassis system uses change blocks to allow for adjustable center wheel drop. The axle mount holes in each block are drilled off-center creating different amounts of drop. Universal Chassis

Since the center wheel typically interacts with your gearbox it is easier in my opinon to move the outer wheels.

This option also allows you to indepoendently adjust the front and rear wheel position. In the past we have raised the front wheel only...leaving the center and rear on plane.

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.
