Problems solved by technology

[0008] The vacuum adsorption wall-climbing robot adopts negative pressure adsorption and alternate suction cups to realize the adsorption and movement of the robot. This kind of robot has strong adaptability to the wall surface, but the walking efficiency is low.
Although the wheeled wall-climbing robot has high walking efficiency, its ability to overcome obstacles is poor

specific Embodiment approach 1

[0032] Specific implementation mode one: combine Image 6 This embodiment will be described. like Figure 6-1 As shown, when the wall-climbing robot encounters an obstacle that can be circumvented while traveling, the specific steps for the robot to overcome the obstacle with a right-angled fold line include:

[0033] Step 1, the first wheel 5-1, the second wheel 5-2, the third wheel 5-3, and the fourth wheel 5-4 are driven by their respective wheel steering motors 4-3, rotate 90° around the Z axis, and after turning The direction of travel of the wheels is parallel to the small cube obstacle 8, and the direction of the wheels after turning is as follows: Figure 6-2 shown;

[0034] Step 2, the wall-climbing robot moves to avoid obstacles, such as Figure 6-3 shown;

[0035] Step 3, the first wheel 5-1, the second wheel 5-2, the third wheel 5-3, and the fourth wheel 5-4 are driven by their respective wheel steering motors 4-3, and rotate 90° in the opposite direction arou...

specific Embodiment approach 2

[0037] Specific embodiment two: When running into an obstacle that can be circumvented, by controlling the wheel steering motor 4-3 in the four wheel foot conversion mechanisms 4, the wheel 5 is driven to rotate a certain angle around the Z axis, and the robot can realize small Obstacle-surmounting function with radial arc omnidirectional movement.

specific Embodiment approach 3

[0038] Specific implementation mode three: combination Figure 7 This embodiment will be described.

[0039] like Figure 7-1 As shown, when the robot encounters an obstacle that needs to be rolled over, the specific steps for overcoming the obstacle include:

[0040] Step 1, control the wheel-foot conversion motor 4-2 in the four wheel-foot conversion mechanism 4 to drive the crossbeam 4-4 to rotate 90° around the Y axis, and complete the adduction of the four wheels 5 relative to the frame 1, such as Figure 7-2 shown;

[0041] Step 2, sequentially control the wheel steering motors 4-3 in the four conversion mechanisms 4, and drive the wheels 5 to rotate 90° around the Z axis, so that the sucker group 7-1 in the wheels 5 is in vertical contact with the wall, realizing the wheel movement of the wall-climbing robot. Foot conversion functions such as Figure 7-3 shown;

[0042] Step 3, start the vacuum air pump 9 installed on the robot frame 1, make the suction cup group 7-1...
