I'd assume the answer is somewhat similar here-- the arc motion is so short, and the cylinder and bar are very well defined, so it isn't necessary to connect the two. |

I think that it is necessary to raise the omni wheel, because it is geared twice as fast as the fixed wheel; it would be spinning against the carpet whenever you were driving in traction generating heat and wearing down the wheel. In Aren's previous answer, he refers to a spring lifting the moving wheel up. I don't see one in the assembly directions, but it may be implicit in the way pieces fit.
