This is video demonstrating the use of omni wheel technology in a wheel chair.

I’ve been looking at possible alternatives to the conventional wheel. At the moment I have been looking at Omni wheel technology. Omni Wheels can move in any direction. The wheels have two ball bearings at the bore of the wheel with many small wheels making up one large one. This would resolve the maneuverability issues I have uncovered with current walking aid products.

In the images is the Airtrax Sidewinder which is one of the first large scale manufacturer of the technology

This is a link to a tutorial to omni robot design that I found helpful in gaining a greater understanding in omnidirectional holonomic platforms. Still not sure if I’ll be able to pursue this path even though I am keen to.
