Omni wheels, similar to mecanum wheels, are wheels 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. It is a method of creating holonomic drive.
A platform employing three Omni wheels in a triangular configuration is sometimes called a Killough platform; so named after Stephen Killough's work with omnidirectional platforms at Oak Ridge National Laboratory. Killough's 1994 design used pairs of wheels mounted in a cages at right angles to each other and thereby achieved holonomic movement without using true omni wheels.[1]
They are often used in small robots. In leagues such as Robocup, many robots use these wheels to have the ability to move in all directions.
