I was looking around youtube typing in random words looking for something new to show you guys and i came across this video. It's showing a fork lift truck that uses AirTrax Omni-Directional Wheels.. "WTF are they?!1?" i hear you ask, well, Airtrax omni-directional technology allows the Lift Truck to move forward, diagonally, laterally, in any direction at all. Pretty hard to explain, So watch the movie..
It is difficult to explain, its wheels are equipped with small discs around the circumference which are perpendicular to the rolling direction. The effect is that the wheel will roll with full force, but will also slide laterally with great ease.
