Here's some pictures of Team 228's 2007 drivetrain and chassis:
The main frame members were 0.125" aluminum fabricated on a CNC sheet metal turret/punch machine. We used Banebots (it wasn't until after we had our drive train powder-coated that we found out how
horrible their quality was) direct drive onto the rear wheel. All axles were live, and the wheels were custom-machined out of blocks of aluminum to 5.5" in diameter.
