[0020] Figure 1 The application scenario of the intelligent transport robot in the company corridor environment is shown. The robot has a compact structure and can autonomously travel in a complex environment. The robot is internally provided with a computer control system which fuses multiple sensor data to realize real-time environment perception and obstacle avoidance; the robot can obtain task instructions of the company information system in real time through a wireless network to realize overall scheduling and task execution closed loop. The safety mechanisms such as emergency stop button and collision detection device of the robot can rapidly respond in emergency situations to ensure safety in the human-robot shared space.

[0021] Figure 2 The structure of the intelligent transport robot is shown. The robot body adopts a small automatic transport vehicle structure, and multiple closed storage cabins are arranged on both sides of the vehicle body, and each storage cabin can be accessed through a safety locking door. The navigation control unit and the interactive interface are mounted on the upper part of the vehicle body, and a laser radar and a vision camera are carried for environment perception and positioning navigation. An audible and visual alarm is arranged at the rear part of the vehicle body to prompt surrounding people to pay attention to the operation state of the robot. The vehicle body is provided with a multi-wheel driving system at the bottom for flexible movement of the robot in the company corridor.

[0022] The closed storage cabin of the robot is provided with a low-temperature storage function, which can be automatically started after the storage cabin door is closed to perform low-temperature treatment on the internal space and the carried objects, thereby reducing the risk of cross-infection in the company. The storage cabin is designed as a multi-cabin structure and can separately place objects or samples of different departments to support simultaneous transportation of multiple tasks.

[0023] The navigation control unit plans a path and assigns a task through a central dispatch system, and realizes autonomous path finding and dynamic obstacle avoidance in combination with positioning and navigation technologies such as laser SLAM. During the operation of the robot, when the navigation module monitors pedestrians or moving obstacles, the robot will immediately slow down and stop, and then re-plan a path to continue moving forward after the pedestrians pass, thereby ensuring safety when sharing a passageway with other personnel in the company.

[0024] The robot control logic is as shown in Figure 3 First, the robot receives a delivery task from the company information system, and then starts the navigation positioning system to plan a path and perceive the environment. During the execution, the robot continuously monitors the surrounding environment, identifies obstacles and avoids them, and at the same time interacts with personnel through the QR code and voice modules to confirm the completion of the task. When approaching the destination, the navigation control unit calls the elevator through the elevator control unit, opens and closes the door through the automatic door control unit to complete the unloading of goods after entering the target floor. After unloading is completed, the robot returns to the charging base or waits for the next task. During the entire process, when the robot loads or unloads goods, the ultraviolet function is started to process the storage cabin to ensure the sterile safety of the goods during transportation.

[0025] In summary, by means of the above technical solutions of the present application, automatic task scheduling is realized through communication with the company information system, and elevator and automatic door control functions are integrated to realize seamless transportation across floors, greatly improving the logistics efficiency in the company. Based on multi-sensor fusion to perceive the environment, dynamic path planning and precise obstacle avoidance are realized to ensure safe operation in densely populated areas. The closed storage cabin is equipped with a low-temperature device to automatically lower the temperature during transportation, effectively reducing the risk of cross-infection in the company. Support for touch, voice, and QR code interaction modes facilitates task confirmation and information management, and improves operation convenience and process traceability.
