Omnidirectional wheels have been around for quite a while, but that doesnt stop us imagining the day theyll finally become practical to use. William Liddiard, a Canadian inventor, created these omnidirectional wheels for his Toyota Echo. Liddiard writes:
I had to improvise a lot, use the materials available to me, and work on it sparingly when I could find the time. I decided to put them on my car. Unlike other omni capable wheels, my wheels do not require the vehicle to be built around them.
