AGV (Automated Guided Vehicles) is also known as unmanned guided vehicles, automatic guided vehicles. Its distinctive feature is unmanned, and the AGV is equipped with an automatic guidance system, which can ensure that the system can automatically drive along a predetermined route (or fixed track) without manual pilotage, and automatically transport the engine from the starting point to the destination. Another feature of AGV is good flexibility, high degree of automation and high level of intelligence, the driving path of AGV can be flexibly changed according to the storage location requirements, production process and other changes, and the cost of running path change is very low compared with traditional conveyor belts and rigid conveyor lines. AGVs are generally equipped with loading and unloading mechanisms, which can be automatically docked with pre-installed lines or test benches to realize the automation of the whole process. In addition, AGV also has the characteristics of clean production, AGV relies on its own battery to provide power, no noise and no pollution during operation, can be used in many places that require a clean working environment.
