EDWARD basicly is a frame and suspension contained between two wheels, with a 5 point harness and can control the machine with a gaming joystick. Its inversion control even allows you to drive upside down (if you are that way inclined).
“EDWARD(Electric Diwheel With Active Rotation Damping) by students in the School of Mechanical Engineering, the University of Adelaide involved the construction of a human operated diwheel called EDWARD. Many diwheels in the past have been human powered or powered by IC engines. This one is purely electric. It has additional functionality lacking in other models, including inbuilt dynamic lateral stability and slosh control to prevent “gerbiling” or tumbling in aggressive braking or acceleration maneuvers. The diwheel also incorporates a unique feature that allows the rider to drive the vehicle when “upside down” – keeping the vehicle in its unstable state
