Nexus Robot 100mm Omnidirectional Wheel (Brass Bearing for Rollers)

Nexus Robot introduces the 100mm Omnidirectional Wheel (Brass Bearing for Rollers) . This omni-wheel could be mounted to Nexus Robot kit 10003 and 3WD Omni-Directional Arduino Compatible Mobile Robot . The Omni-directional wheels are unique as they are able to roll freely in two directions. The Omni-direction wheels allow a robot to convert from a non-holonomic to a holonomic robot. A non-holonomic robot that uses normal wheels has only 2 out of 3 controllable degrees-of-freedom - moving forward/backwards and rotation. Not being able to move side ways makes a robot slower and less efficient in reaching its given goal.
