EDWARD, It’s Not a Bicycle, It’s a Diwheel

Mechanical engineering is one of the fields I regret not pursuing. It gives me great pleasure to hear about these amazing projects those students come up with...
Ramy still didn't hear about an invention of yours I'm waiting for it... :p Maybe you can give me a little feed back about the quality of this invention, can it replace wheel-chairs?

Enjoy the video...

A group of engineering students at the University of Adelaide have built a vehicle that would be perfectly at home in just about any science fiction movie you’ve ever seen: Electric Diwheel with Active Rotation Damping, or EDWARD for short.

Here’s an overview from the project page:
This honors project involved the construction of a human operated diwheel. 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 is achieved using a combined swingup and inversion controller. The mechanical design and some of the electronics was completed in 2009, with the majority of the electronics and control systems developed in 2010.
