The 152mm Right Aluminum Mecanum Wheel includes a series of rollers attached to its circumference, these rollers having an axis of rotation at 45° to the plane parallel to the axis of rotation of the wheel.
The Mecanum wheel uses a standard chassis shape and powers each wheel with a different motor, which can be capable of moving in any direction, no need to change the directions the wheels spin. This design enables the wheel to propel your robot forward, backward, and directly sideways.
