The walking system includes a walking drive motor 211 and walking wheels 212. The lifting system includes a lifting drive motor 223, a lifting plate 221, and a lifting link 222. Lifting plates 221 are provided on both sides of the vehicle body. The lifting plates 221 on both sides are connected by the lifting link 222. The lifting plates 221 on both sides are driven synchronously by the lifting drive motor 223 and the lifting link 222.

[0027] Battery 26 provides power to the automated storage and retrieval system robot.

[0028] The automated storage and retrieval system (AS / RS) robot also includes a switch 25, a PLC control unit 24, a drive unit, a communication unit, and various sensing devices. The switch, PLC control unit, drive unit, communication unit, and various sensing devices are all mounted on the vehicle body.

[0029] like Figure 5 As shown, various sensors are directly connected to the PLC control device 24, which receives various sensor data; the PLC control device 24 is connected to the switch 25, which processes various communication data and sensor data, and issues control commands.

[0030] The drive unit includes a CAN card, a driver, a motor, and an actuator. The motor is connected to the switch 25 sequentially via the driver and the CAN card to receive control commands from the PLC control unit 24. The actuator, driven by the motor, performs the movement and lifting / reversing tasks of the automated storage and retrieval robot in the sub-rail and main rail directions. The driver receives commands from the controller and converts them into drive signals for the motor and actuator.

[0031] In this embodiment, a dual-mode vehicle-mounted wireless terminal is used on the automated storage and retrieval system (AS / RS) robot, along with a Wi-Fi antenna and a 5G antenna, to achieve dual-mode communication capability for the AS / RS robot.

[0032] Simultaneously, a network topology centered around the PLC and switches is adopted to enable the access of various electrical components, enriching and improving the warehousing operation capabilities of the automated storage and retrieval system (AS / RS). In this implementation, various functional components can be connected to the switches and then processed through the PLC control device. This layout is more systematic, component expansion is simpler, and it does not cause crosstalk between various components.

[0033] The motors include a walking drive motor 211 and a lifting drive motor 223. The actuators include walking wheels 212, a transmission mechanism (not shown), a lifting support plate 221, and a lifting connecting rod 222.

A CAN card, also known as a PCAN-USB, is a CAN-to-USB interface device.

[0034] The communication device includes an on-board wireless terminal, a Wi-Fi antenna 241 and a 5G antenna 242. The Wi-Fi antenna 241 and the 5G antenna 242 are connected to the switch 25 through the on-board wireless terminal to realize communication between the automated warehouse robot and the outside world.

[0035] Wi-Fi antenna 241 and 5G antenna 242 are respectively arranged around the vehicle body. Specifically, in this embodiment, the Wi-Fi antenna is arranged on the front side of the vehicle body, and the 5G antenna is arranged on the left or right side of the vehicle body. However, those skilled in the art should understand that the arrangement of Wi-Fi antenna 241 and 5G antenna 242 is not limited to this. In order to achieve better signal propagation, Wi-Fi antennas are arranged on both the front and rear sides of the vehicle body, and 5G antennas are arranged on the front, rear, left, and right sides of the vehicle body.

[0036] When using the device, you can choose to use either Wi-Fi or 5G signals depending on the on-site working environment and configuration strategy.

[0042] The dual-mode communication automated warehousing robot also includes a LiDAR (not shown) and an RFID reader 28. The LiDAR detects environmental information to achieve obstacle avoidance, while the RFID reader detects information about the pallet or the location of the storage space. The LiDAR and RFID reader are connected to a switch 25. The information acquired by the LiDAR and RFID reader is transmitted through a communication device connected to the switch. The RFID reader is mounted on the warehousing robot, specifically on the upper and lower sides of the vehicle body. During reading and writing, the RFID reader on the upper side of the vehicle body can be as close as possible to the bottom of the pallet to read the RFID tag information from the pallet; the RFID reader on the lower side of the vehicle body... F The ID reader reads the RFID tag information on the shelf location.

[0043] The LiDAR (Light Detection and Ranging) is mounted on the four sides of the vehicle body. Preferably, in this embodiment, the LiDAR is mounted on the left and right sides of the vehicle body, arranged diagonally.
