[0002] In traditional intensive warehousing and logistics, pallets are transported in and out of the warehouse by a large number of manual forklifts and related technical workers. In recent years, the robotics industry has developed rapidly, and the speed of technical equipment iteration and upgrading has continued to accelerate. A large number of companies have gradually adopted RGV (rail-guided shuttle vehicle) or AGV (automatic guided vehicle) to replace manual forklifts and technical workers.

[0003] In today's intelligent warehousing and logistics, RGV (rail-guided shuttle vehicle) or AGV (automatic guided vehicle) is no longer applicable. The main reason is that the existing AGV transportation can only operate on designated routes, which is extremely restrictive and has relatively low controllable accuracy. The overall control also requires human software for real-time monitoring. Whether in terms of real-time performance, stability or safety, it cannot meet the development speed of existing intelligent warehousing and logistics. Summary of the invention
