AGV is an automated driverless vehicle with its own power and non-contact guidance device. Its main function is to enable the trolley to walk more accurately and stop at the designated place to complete a series of operation functions under the computer monitoring, according to the path planning and operation requirements. AGV is characterized by wheeled movement. Compared with walking, crawling or other non wheeled mobile robots, AGV has the advantages of rapidity, high efficiency, simple structure, strong controllability and good safety. It can be well matched with the stacker, monorail trolley, conveyor belt and conveyor chain roller table commonly used in material conveying. The AGV activity area does not need to lay rails, support frames and other fixed devices, and is not limited by the site, roads and space. Therefore, in the automated logistics system, Z can fully reflect its automaticity and flexibility, and realize efficient, economical and flexible unmanned production.
