As part of your holdback (30# of fabricated items), build a Boulder Blocker to make your robot just shy of the 54" height limit. Bolt it on when you get to Champs. IMHO, but it on all 4 sides of your robot, and put a cover to keep boulders out.

For low robots that shoot the high goal, the Blocker may be all you need. The rest you have to push around.
