We intend to make a short robot, the electronics will be on the side near the front, the ball will go down the center of the robot (in one end, out the other).

The lower four wheels are mounted on aluminum brackets, we were very careful to keep the center to center distance for the belts just right, so it took a few days to perform the modifications.

What ideas have you come up with to deal with this?

This is great! We actually came up with a similar solution with our 8" Pneumatic 8WD. Front wheel is raised about 2 inches, making the pass over the rock wall and rough terrain easy. We also crammed the 8 wheel profile into as short of a length as possible, to ensure continuous wheel contact with the defenses.
