It is a 6 wheel drive chasis. The two black wheels are omni wheels and the orange wheels are traction wheels. The center wheel is not lowered. The frame is made from 1" 6061 alluminum with 1/8" wall thickness and weighs under 20 pounds. Everything weighs around 35 pounds. There is a bearing holder acrost from the transmission to support a shaft.
- Should the center wheel still be lowered eventhough there are 2 omni wheels?
- Is 1/8" walls strong enough or should it be thicker?
