More details

The vehicle is a circular-shaped electrically powered car with three wheels. Each wheel is driven independently and can also rotate about its axis. The car will be able to drive in any direction as well as spinning on the spot. Driving along while rotating and doing waltz-like maneuvers are also possible. It will be controlled by a joystick and some other controls by a driver who sits with the other people facing inwards on the circular couch.

There will be nine microprocessors - two in each wheel controller and one central unit coordinating the motions - posing a considerable software challenge. They will all communicate using an RS485 serial link. We are driving this car using three e-tek motors for about 6 hp of continuous power. The maximum loaded weight will be about 1300kg and we should be able to go from 0-10mph in around 3 seconds with a top speed of around 15mph.

We will probably incorporate a sound system and some crazy lighting.

We have one expert on machining and mechanical design and one expert on electronics. The remaining people have a broad skill range and will contribute in many areas.
