Mecanum wheel is a device that can move in all directions. This omnidirectional movement method is based on the principle of a center wheel with many axles located around the wheel. These angled peripheral axles transform part of the steering force of the wheel into one The normal force above the wheel.It is mostly used in robots, logistics warehousing equipment and AGV handling trolleys to achieve omnidirectional motion, which can realize forward, lateral, oblique, rotating and combinations of motion modes.
