1.The key technology of adsorption mechanism has been overcome, and a series of wall-climbing robot platforms of various specifications have been developed. 2.Remarkable progress has been made in adaptive adsorption techniques on different rough wall surfaces and in on-line identification and detection of bridge damage. 3.The obstacle climbing robot, based on the bionic obstacle climbing robot, can cross steps, positive and negative obstacles, complex obstacles and environments from the ground to the wall, and from the wall to the ceiling. Have been authorized invention patent by China Patent office. 4.The core eddy current component of the obstacle climbing robot adopts 3D printing technology with high efficiency and excellent performance. In the eddy current negative pressure adsorption technology, the adoption of negative pressure automatic detection and adaptive control technology can reduce the damage rate of obstacle climbing robot products by 85%.
