Canadian inventor creates omni-capable wheels
A Canadian inventor has developed an “omni-capable” wheel that allows cars to “strafe” sideways into a parallel parking space.
The new wheels have been named Liddard wheels after the inventor, William Liddard. Liddard built the prototype wheels on his own and fitted them to his personal car, a Toyota Echo.
The wheels and tires allow the car to move side-to-side in a crab-like motion. Or, if front and rear wheels are rotated in opposite directions, they can spin the car like a tank. Unlike other omni-directional wheels from sci-fi movies and the like, Liddard’s don’t require the car to be redesigned to accommodate the wheels. They can be bolted on to any vehicle without modifying the vehicle itself.
The wheels were “designed to be used in all weather and road conditions,” said Liddard in the video description of the clip he uploaded to YouTube. “They can take a beating. The tires ‘can’ have the same build characteristics (siping, grooves, rubber compounds etc.) as regular tires. Now you can drive in all directions, and turn on the spot, when needed.”
Liddard also hints that the strafing motion can be made faster if a lower gear ratio is used, and that they can be fitted to anything with wheels. Watch the video below.
