Amazing tutus.. that looks nearly like the suspension I drew up for my mentors..
1 question tho.. how do you plan on keeping any chains or kevlar intact.. in your design you have no motors showing so I assume the drive source is elsewhere. What happens ( and this may rarely happen in FIRST application.. but just a question ) when 1 side goes up and the other goes down.. you will have cause your chain to be on a angle to the drive. and run a high risk of it to come off.. or snap.. or not mesh with the sprockets correctly. The gear box would have to move in sink the wheel well dealio.. or.. it would have to be mounted on the wheel itself.. which in your situation would be best... However.. you could use U-Joynts and a drive shaft.. but then that would kinda defeat the purpose of crab.. and you would be way too inefficient
only problem we discovered with crab + suspension would be keeping it light enough yet strong enough so that in constant highspeed ramming matches ( which is first ) your suspension would not snap and your wheels fall to the floor.
