Ford Ka Becomes Diwheel Monster

If you’ve been to the right events, you’ve seen them before – the cars with an external cage that let the car complete a somersault in the forward direction under heavy braking. They’re impressive, but it’s possible to take things even further. Enter [mastermilo82] and the RollKa.

The RollKa follows on from the RollGolf, which was a straightforward roll car build. Built around a Ford Ka, it eschews the external cage for a more radical design. The Ka has been shortened, and designed to fit within two enormous steel rims which wrap around each side of the car. Additional idler wheels have been welded to the Ka’s roof to enable it to effectively roll within the outer steel rims.

It’s a rather eccentric design, known as a diwheel. We’ve seen impressive electric versions before, but at least at this stage, this project appears to lack any advanced control systems and gets by on sheer luck and welding prowess. The build is still at an early stage, with episode three┬ástarting some early movement tests under power. It’s a testament to what can be achieved with a spacious garage and some imagination, and we can’t wait to see what happens next! Video after the break.

EDWARD The Vehicle Of The Future

If there was a competition for coolest transportation device for the future, the diwheel would be at the top of the list with hover cars and teleportation. Over the past 3 years students at Adelaide University have been working on an Electric Diwheel With Active Rotation Damping or EDWARD.

EDWARD is an entirely electric diwheel, the operator is strapped into the bucket seat between the two large wheels with a 5 point harness and can control the machine with a gaming joystick. Full dynamic stability and slosh control allow the operator to maneuver the vehicle at up to 40km/hr, inversion control even allows you to drive upside down (if you are that way inclined). The next question is just where can we get one? Check out the video after the break for a demonstration of EDWARD in action.
