1. With the rising labor cost, it is an important direction of modern robot research to use robots instead of manpower to do some repetitive and high-intensity labor.
2. At present, in the logistics system and flexible manufacturing system, the automatic navigation car has been widely used, but its main guidance mode is electromagnetic or inertial guidance. Electromagnetic guidance needs to bury metal wires and load the guidance frequency, which has obvious shortcomings, poor flexibility, trouble in changing or expanding the path, and interference with ferromagnetic substances near the conductor.
3. Gyroscope is mainly installed in inertial guidance, but its disadvantages are high cost, maintenance and other follow-up problems are difficult to solve, and the ground also needs magnetic block to assist positioning. In addition, this kind of car lacks the function of distinguishing objects.
All of the above are about the background of the development of sorting robots.
