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%...
Generally, it consists of four wheels, two left wheels, and two right wheels. Left-handed and right-handed wheels are chiral symmetric, as shown in the picture below. There are many installation methods, which are mainly divided into X-square, X-rectangle, O-square, and O-rectangle. Where X and O represent the pattern formed by the rollers in contact with the ground of the four...
In racing robots and special types of robots filed, omnidirectional movement is often a required function. "An omnidirectional movement" means an action that can be rotated in any direction while rotating in the plane. In order to achieve omnidirectional movement, the general robot will use two special wheels, the Omni Wheel or the Mecanum Wheel. This is the Omni Wheel: 60mm...
