AGV (Automatic Guided Vehicle) trolley capable of walking in any angle direction

Abstract

The invention belongs to the field of automated guided vehicles, particularly provides an AGV (Automatic Guided Vehicle) trolley capable of walking in any angle direction and aims to solve the problem that the conventional AGV trolley inconveniently operates in a narrow space because of minimum turning radius. The AGV trolley capable of walking in any angle direction comprises a trolley body and four driving units, wherein the driving units are fixedly connected to the trolley body via crossed roller bearings; each driving unit is composed of two groups of driving motors; driving wheels are arranged on output shafts of the driving motors; two driving wheels are symmetrically arranged on two sides of an axle center of each bearing; one of the driving wheels on the two sides rotates forwards while the other of the driving wheels on the two sides rotates backwards, the driving units can rotate around the bearings; when the two driving wheels rotate in the same direction, the driving units drive the AGV trolley to move. The AGV trolley is capable of walking in any angle direction, so that the AGV trolley can operate in extremely narrow space and has extremely strong space adaptability.

Description

technical field [0001] The invention belongs to the field of automatic guided vehicles, and specifically provides an AGV trolley that can walk along any angle direction. Background technique [0002] Automated Guided Vehicle (AGV for short) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, capable of driving along a prescribed guiding path, and having safety protection and various transfer functions. In industrial applications, the truck does not require a driver, and uses a rechargeable battery as its power source. Generally, the computer can be used to control its travel route and behavior, or the electromagnetic track can be used to set its travel route. Usually, the electromagnetic track is pasted on the floor, and the unmanned van moves and moves according to the messages sent by the electromagnetic track. [0003] AGV is characterized by wheeled movement. Compared with walking, crawling or other non-wheeled mobi...
