Excellent work.

As you reorient the battery and main breaker, consider that these are the wires that you want to keep as short as reasonable, since they carry the greatest current. Also, the battery connector needs to be considered, since teammates will be connecting and disconnecting that battery often.

An alternative to gusset bars are plates, triangular in shape as you ahve the bars, but they are easier to fabricate and mount without welding.

Lastlly, consider how the wheels are driven, since sprockets have a thickness that cannot be ignored. Oh, and think about how to mount bumpers, assuming they'll be a good idea for the 2010 game.
