The first AGV was introduced in 1953 and was defined as a vehicle that solves the problem of unmanned handling and transportation in the field of industrial logistics. However, the early definition of AGV was simply "a transport vehicle that moves along a guide line laid on the ground" as we understand it literally.
Because mobile robot technology was underdeveloped in the 20th century, the AGV industry has undergone more than 40 years of development, and the AGVs on the market are still iterating and upgrading based on guidance technology.
With the development of mobile robot technology, laser navigation technology has emerged to eliminate physical guide lines on the ground. It solves the problem of precise positioning of AGVs by using high-position reflectors and positioning laser radar, and then replaces the physical guide lines on the ground with virtual guide lines in the software. AGVs using this technology are called LGVs (Laser Guided Vehicles), and most unmanned forklifts are currently LGVs.
