Mecanum wheels, also known as omni wheels or ilon wheels, consist of a hub with rollers oriented 45° to the axis of rotation.

Perfect for tight spaces, they enable conventional forward & backward movement as well as side to side and even rotation. To accomplish this, each wheel turns independently. To move side to side, pairs of wheels oppose one another, acting like a worm gear.

You'll see a forklift like this one from time to time in the background on the show Mythbusters!
