Description

Technical Field

[0001] The invention belongs to the technical field of robots and relates to a wall-climbing multi-habitat robot. Background Art

[0002] Drones or various wall-climbing robots are now commonly used as inspection platforms for large building facades, industrial equipment, and tunnels. Current wall-climbing robots are capable of operating on complex surfaces, including flat, convex, concave, and inclined surfaces. Drone technology has also advanced rapidly in recent years, possessing autonomous positioning, navigation, control, and navigation capabilities. The increasing precision of various sensors (accelerometers, gyroscopes, magnetometers, cameras, etc.) has significantly enhanced robots' ability to determine their position, posture, and surrounding environment, leading to their widespread use across various industries. Wall-climbing robots and drones offer a wide range of advanced control algorithms and control system solutions. Through high-definition imagery and high-precision sensor acquisition, these robots can provide accurate information about the exterior walls of inspected objects, enabling them to detect subtle defects and damage. They can also capture panoramic images of exterior walls and generate stereoscopic images using 3D modeling, making defects and damage more readily apparent. In materials science, the emergence of various materials with high strength, light weight, flexibility, and wear resistance has enabled robots to be made smaller and more robust. However, both wall-climbing robots and drones have certain defects when performing the above operations.

[0003] Common wall-climbing robots today include wheeled, legged, suction-cup, and magnetic robots. Wheeled robots offer the advantage of simple control and stability, but their disadvantage is that they are not suitable for irregular or poorly shaped surfaces. Legged robots offer the advantage of good adaptability and gripping strength, but they are more difficult to control and have slightly lower control stability. Furthermore, since sufficient friction is required to maintain grip on all four legs, energy consumption is high. Both types of robots can also cause significant damage to the surface during operation. Suction-cup robots have similar advantages to legged robots, but their disadvantage is that they require high surface flatness and material quality. Furthermore, environmental changes significantly affect the suction cup's grip. The disadvantage of magnetic robots is even more pronounced, as they can only be used on smooth metal surfaces.

[0004] As for drones, thanks to the contributions of researchers around the world, drone technology is now very mature, and the control accuracy of drones has made a qualitative leap in all aspects. However, drones have high requirements for weather (wind is as low as possible). Summary of the Invention
