TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics equipment, and specifically refers to an AGV equipment. BACKGROUND

[0002] In the logistics industry and special production sites, traditional cargo transportation and management methods usually include the following: (1) manual handling: manual operation relies on workers to manually transport goods from one location to another. This method is labor-intensive, inefficient, and prone to errors and accidents; (2) forklifts and other mechanical equipment: heavy machinery such as forklifts are used to transport goods, which improves efficiency to a certain extent, but still requires manual driving and maintenance, poses safety hazards, and requires high operating skills; (3) conveyor belt system: conveyor belts are used for automated transportation in some specific scenarios, but this method has poor flexibility, limited scope of application, and difficulty in dealing with complex warehouse environments; (4) traditional warehouse management system: barcodes or RFID technology are used for item tracking and management, but manual intervention is still required to perform inventory management, picking, and distribution tasks.
