The shafts were lathed by hand (we used keyed shafts since they were easier to machine), and the wheels, hubs, and transmission components all came from Andymark. If you simplify the design, it isn't hard to make.
The Cheesy Poofs transmission, on the other hand, is quite difficult to replicate as basically all of the gears are custom-made by them.
33 robot stats (We were on the top 25, so that qualifies us?)
-8 wheel (6" wheels) live-axle DualDrive combining Plaction, KOP, and Lunacy wheels. Two wheels are actuated by pneumatic pistons, automatically.
-2-speed, 4-CIM transmission (5.5 and 12 ft/sec)
