Description
Technical Field
[0001] The utility model relates to the technical field of AGV robots, in particular to an AGV robot for warehousing logistics transportation. Background Art
[0002] An AGV robot, that is, an automatic guided vehicle, is a robot that can be automatically guided and moved. They track ground marks through vision, magnetic navigation, laser or other means to achieve functions such as automatic navigation, movement, multi-sensor control, and network interaction. AGV robots achieve various tasks by receiving and interpreting built-in computer code instructions, including transporting materials, assembling parts, and warehouse management. They use different navigation methods, such as magnetic strip guidance, laser guidance, RFID guidance, etc., to automatically transport materials to designated locations. In order to adapt to transporting goods with a larger width or transporting more goods at a time, the load-bearing surface of the AGV robot is often designed wider than the body of the AGV robot, and AGV robots are often used in warehousing logistics transportation, thereby improving the transportation efficiency of goods and reducing the labor intensity of workers.
[0003] Regarding the above related technologies, the inventor found that when AGV robots are used in warehousing logistics transportation, there may be some narrow passages, door openings or gaps between shelves in the warehouse. At the same time, there may be warehouse workers, temporarily placed goods or other non-static obstacles (such as maintenance equipment, etc.) on one side of the passage. When the AGV robot encounters these obstacles during driving, it needs to wait for a certain period of time for the workers to remove these obstacles, or take a detour to transport the goods, thereby reducing the efficiency of the AGV robot in transporting goods. Summary of the Utility Model
