DIY mecanum wheels (4 inch)100mm Aluminum Mecanum Wheels Set Basic ( 2 Left, 2 Right) 14162

This 100mm (4-inch) mecanum wheel set includes 2 right-handed wheels and 2 left-handed wheels, with each wheel featuring 9 rollers. Each wheel

 is independently driven, allowing for full directional mobility. Mecanum wheels enable omnidirectional movement — the vehicle can move forward, 

backward, sideways, or diagonally without changing the rotation direction of the wheels.

Each of the four wheels contains a series of rollers, which are mounted at a 45° angle relative to the plane of the wheel. This angled orientation allows 

for smooth and precise multidirectional motion.

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.
