During the off-season Arthur Siebel led a project to build an eight-wheel drive prototype. It is geared at 13.5 feet per second using 3-inch Colson wheels. With electronics, it weighs 42 pounds. The gearbox is single-stage made from standard commercial-off-the-shelf gears we had in the shop. It was simple to make and will be easy to manufacturing during the season. This prototype uses eight single-piece wheel assemblies. These are tied to the main drive axle by chain. This simple single-piece design allows for lighter overall product that will always be able to drive, even if a chain breaks or is disconnected during competition.
