Behind the scenes of Discovery Channel's Prototype This from the Traffic Busting Truck episode. This was a test couch that we built to verify the functionality and control of the Airtrax omnidirectional (Mecanum) wheels. Control is achieved by a wireless Playstation 2 controller, its data being received by a BASIC Stamp and processed to send the required analog voltages to the Airtrax control box.
