Now for the Rover, it will move itself....
The Rocker Box and Rover were built in parallel. I did not want to mar the Urethane coat trying to get a heavy steel structure built around it. The four steel sides bolt at their corners, with a scissor jack lift axle on one side and a trailer jack on the other for a three point drive system. The wheels are doubled to handle the weight of the entire lower scope and Rover. The trailer jack wheels are sprocketed to drive itself, I only need to steer.
