The binocular depth camera 701 is mounted on the robotic arm 602, and the millimeter-wave radar 702 and odometer 703 are mounted on the mobile device 1. The binocular depth camera 701 can transmit the RGBD image information of the borehole working face and the RGBD image information of the emulsion explosive 603 in the explosive loading box 601 to the control device 5 respectively. The millimeter-wave radar 702 identifies borehole locations and emulsion explosives using RGBD image information, detects the depth of each borehole, and transmits this depth information to the control device 5. The control device 5 determines whether the depth of each borehole meets predetermined requirements. If it does, the borehole is identified as a location requiring the filling of emulsion explosives 603. The odometer 703 transmits the location information and distance traveled by the mobile device 1 to the control device 5 for positioning.

Based on the RGBD image information in front of the gripper 6022, the emulsion explosive 603 and the position of the blast hole are identified.
[0153] In one possible implementation, the explosive mounting box 601 is mounted on the upper surface of the lifting part 2.

[0157] Specifically, after the program is executed by the processor, it can identify the position information of each blast hole and each emulsion explosive 603, and control the robotic arm 602 to pick up the emulsion explosive 603 at the confirmed position and fill it into the blast hole.
[0158] In one possible implementation, when the program is executed by the processor, it can also perform the following steps: acquiring the initial relative position information of the mobile device 1 relative to the working face of the borehole when it is not moving, based on the millimeter-wave radar 702; generating an initial navigation path for the mobile device 1 to travel to the working face of the borehole based on the initial relative position information; controlling the mobile device 1 to travel along the initial navigation path, and detecting the presence of obstacles in real time through the lidar 705 and the ultrasonic obstacle avoidance sensor 706; if so, acquiring the obstacle's relative position information relative to the working face of the borehole; generating an avoidance navigation path based on the obstacle's relative position information, wherein the avoidance navigation path is a navigation path that avoids the location of the obstacle; and controlling the mobile device 1 to travel to the working face of the borehole based on the avoidance navigation path.
[0159] Specifically, after the program is executed by the processor, it controls the mobile device 1 to travel to the working face of the blast hole according to the avoidance navigation path.

[0161] Specifically, after the program is executed by the processor, the clamping force of the gripper 6022 on the emulsion explosive 603 is maintained within a preset range to avoid the clamping force being too large or too small. This ensures that the clamping force of the gripper 6022 and the position movement of the robotic arm 602 work together to prevent the emulsion explosive 603 from falling or being damaged, and to improve the loading accuracy.
