[0009] Preferably, the inventory is performed as follows:

[0010] Return to zero: The five-axis motor drives the manipulator to return to the origin in reverse order. After the origin switch is valid, it decelerates and stops, and then rotates forward. It stops after detecting that the origin switch is invalid. The return to origin is completed, and the position is set as the zero point;

[0011] Record: Turn on the color sensor of the robot, and the linear guide rail drives the robot to run in an S-shaped trajectory. The color label of the file grid is detected and converted into coordinate information and sent to the host computer. The color mark of each layer is detected in turn to complete the initialization;

[0012] Initialization: Through the QR code scanner on the robot, the linear guide drives the robot to run in an S-shaped trajectory, sends the detected QR code to the host computer, scans each layer of files in turn, and completes the inventory. This application uses a color sensor and a QR code scanner in combination. The color sensor can achieve fast and accurate positioning, and the QR code scanner can reconfirm the content. The inventory operation also establishes an automatic correspondence between color tags and QR codes, preparing for the subsequent warehousing and outbound operations.

[0013] Preferably, warehousing is performed as follows:
