A Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. It is sometimes called the Swedish wheel or Ilon wheel after its inventor, Bengt Erland Ilon (1923–2008), [ 1 ] who conceived of the concept while working as an engineer with the Swedish company Mecanum AB, and patented it in the United ...
These wheels are often employed in holonomic drive systems. A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive. The Killough platform is similar; so named after Stephen Killough's work with omnidirectional platforms at Oak Ridge National Laboratory. Killough's 1994 design used pairs of wheels ...
The omnidirectional drive consists of three Mecanum wheels, all of which are individually controllable.These wheels are arranged at angles of 120°. Robotino has a bumper sensor around its circumference, infrared distance sensors, a color camera with VGA resolution, optical wheel encoders, power measurement for the entire system and the various motors, as well as a battery voltage monitor.
A Kiwi drive is a holonomic drive system of three omni-directional wheels (such as omni wheels or Mecanum wheels), 120 degrees from each other, that enables movement in any direction using only three motors.
A hemispherical omnidirectional gimbaled wheel (HOG wheel) is a drive system utilizing a hemisphere spinning continuously on its axis. When the hemisphere is horizontal, it is like a spinning top, and applies negligible torque to its contact point on the ground. When tipped on edge, however, it pulls like a traditional circular wheel.

The omni-directional wheels allow the Silver Lightning to be able to steer freely in any direction, and are enclosed in rings integrated within the car's main body. [ 3 ]
The Voith Schneider propeller was originally a design for a hydro-electric turbine. [2] Its Austrian inventor, Ernst Schneider, had a chance meeting on a train with a manager at Voith's subsidiary St. Pölten works; this led to the turbine being investigated by Voith's engineers, who discovered that although it was no more efficient than other water turbines, Schneider's design worked well as ...
