Those outer sprockets are my biggest concern with this design. I'm considering taking the hit on wheelbase to extend the front and rear frame members.

I put the second frame that high so that it was supporting the middle of the bumpers. Since the bumpers are as low as possible, I was worried about the moment created when running into a robot with the bumpers in the higher end of the bumper zone.
