Omni wheel

The effect is that the wheel can be driven with full force, but will also slide laterally with great ease.

A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive.

Omni wheels are also sometimes employed as powered casters for differential drive robots to make turning faster.

Omniwheels combined with conventional wheels provide unique performance properties, such as on a six-wheeled vehicle employing two conventional wheels on a center axle and four omniwheels on front and rear axles.

The Spaceships of Ezekiel describes his process for the "discovery" and recreation of the Omni wheel as well as a traveling craft and its docking station.
