Background

AGVs are key pieces of equipment for automated logistics transportation systems and flexible manufacturing systems, with autopilot functionality in unstructured environments. International research on AGVs started in the united states of the 50 th century, and through continuous development for several decades, AGVs have been commercialized and widely used in various fields such as electronic mechanical manufacturing, logistics, and automated warehouse. With the development of economic technology, enterprises in China gradually start to apply the AGV.

In general, in order to adapt to uneven ground, ground steps and grooves, a suspension spring mechanism is added to a driving wheel so as to increase the friction force between the driving wheel and the ground, so that the driving wheel and the ground cannot slip. However, when the spring mechanism is suspended, the spring force is difficult to adjust in the light-load and heavy-load switching process, and the AGV body needs to be integrally lifted and carried when moving manually, so that physical force is very consumed.
