Advantages of Mecanum wheel Traveling in all directions and accurate positioning Mecanum AGV can travel smoothly in all directions and change direction freely. Moving into narrow spaces and accurate positioning are possible. It is suitable for applications that require transport within less space and accurate positioning. Efficient use of inner space of the AGV Mecanum wheel AGV can travel in all directions without changing the direction of the wheels. As a result, a large space for placing batteries and control devices is available around the wheels and motors, allowing more efficient use...

Controlling the rotation direction and speed of the four Mecanum wheels makes it possible to move the AGV freely. The relationship between the wheel rotation direction and AGV traveling direction is described by the figures shown below. The following figures show the vehicle status when viewed from the top. © 2020 Nabtesco Corporation. All rights reserved.
