Re: pic: Plywood Butterfly Drive Render

If it simplifies the design, you could consider the option of using shifters for the central gearboxes rather than a pulley reduction between the traction and omni wheel. That way, you can shift from high speed to high torque independently of which wheels are on the ground and pivoting about the traction wheel isn't a big hassle. However, this is added complexity.
