The advantages and disadvantages of the Mecanum wheelcmtendency
The advantages of the Mecanum wheel: omnidirectional movement, cool shape. Then there are the disadvantages: expensive, difficult to process (90% are metal), heavy, slow, long life (relative to the traditional rubber wheel), each motor has to drive each wheel separately and then the advantage of the omnidirectional wheel : Large robots can reduce lateral friction (increasing life), cheaper (90% are plastic), simplified structure (round chassis with three omnidirectional wheels), and some designs It can be driven by only two motors: it can be pushed laterally (the lateral direction cannot be fixed), the load-bearing is not possible (may also be a design problem)
The Mecanum wheel is a wheel designed by the American company Meinum to move the materials on the aircraft carrier. Compared with the omnidirectional wheel, the wheat wheel can synthesize the resultant force in any direction by its rotation speed and installation method. So it can move the car in all directions, so the wheel of the wheel needs four motors to drive each wheel separately. Then the owner of the service robot is used because it can move in all directions and is very flexible.
There is a large Mecanum wheel, used on the forklift, it means that the load is not too bad, but certainly not comparable to the traditional rubber wheel. However, the individual feels that the wheat wheel is more reliable than the omnidirectional wheel. Then there is the price problem, the wheat wheel is really expensive… There are more than 300 ordinary robot games, and the wheat wheel needs to strengthen the friction on the ground because of its design problem. Rubber is used on each small wheel. So it is not wearable on some floors. This is why it is not long-lived, it will be thrown almost… and then because it is a pure metal structure, so … heavy, expensive, difficult to process (it seems that there is no cnc out, it is a tradition Bend) Omnidirectional wheels, generally made of plastic, are much cheaper. It is generally seen in small robot games. Like VEX, Make X, FTC, etc. Of course, it is also useful to use FRC. After all, the robot is too large to reduce the steering friction.
