the easy way would be to just to litterally fly. but barring gas fuel or nuclear fusion I'm thinking that might be a little advanced for most teams.... otherwise I think my team figured it our you'll need almost a 16-18 inch wheel to get over the "bump" and that's provided you end up with something like 10 inch casters or you can stick to the tried and true methods of tank drive and offset wheels (one higher and the rest normal.) your real worry should be about flipping (cringes at thought of Icarus last year)
