What are the advantages and disadvantages of the mecanum wheel?

Much easier to climb ramps with Mecanums. To my understanding Mecanums are also more efficient in forward and reverse directions (like a normal wheel) while still giving you lateral mobility. Omni-Drives will give you true omnidirectional motion.

The advantages of the Mecanum wheel and the omnidirectional wheel are flexibility and convenience, and the disadvantage is expensive. The omnidirectional wheel, as the name suggests,

 can move in any direction, at any angle, and in any direction. mecanum wheel these rollers having an axis of rotation at 45° to the plane parallel to the axis of rotation of the wheel.

How you connect the heavy duty mecanum wheel to motor drive? you may need to customize some shaft, hub, washer....
