Background
With the rapid development of the robot industry, the autonomous mobile robot becomes a hot spot for the development of the robot industry. The mobile robot based on the Mecanum wheels has omnidirectional movement capability, so that the mobile robot is more flexible to operate compared with an incomplete wheel type mobile robot, and more attention is paid to engineering personnel.
The Mecanum wheel is a wheel moving based on an omnibearing moving mode, and is characterized in that a plurality of peripheral rollers capable of freely rotating are arranged on a rim along a direction forming an angle of 45 degrees with an axis on the basis of a traditional wheel, the peripheral rollers forming an angle convert a part of hub steering force to a hub normal force, and the forces finally generate a resultant force vector in any required direction depending on the direction and the speed of each hub, so that the platform can freely move in the direction of the final resultant force vector without changing the direction of the hub. Through the combined use and control of the Mecanum wheels, the vehicle body can move and rotate in any direction in a motion plane.
