Wall-climbing robot foot pad based on electromagnetic attraction

Abstract

The invention provides a wall-climbing robot foot pad based on electromagnetic adsorption. The robot foot comprises an adsorption layer and an electrifying wire; a plurality of ferromagnetic particlegroups are distributed on the adsorption layer, and each ferromagnetic particle group comprises a plurality of ferromagnetic particles; the electrifying wire is laid on the adsorption layer, the electrifying wire is provided with at least one annular structure, and the two ends of the electrifying wire are provided with a current input electrode and a current output electrode respectively; when the current input electrode and the current output electrode are connected with a power supply, the annular structure generates annular current. According to the wall-climbing robot foot pad, a plurality of miniature annular circuit arrays and ferromagnetic particles are adopted to generate electromagnetic adsorption force; adsorption force is controlled through on-off of a circuit and current, adsorption and stripping of the foot pad are easy to achieve, the circuit is made through a printed circuit technology, the wiring density is high, the weight and thickness are low, the size of each miniature annular circuit is smaller than the millimeter level, and the whole foot pad is small in size and low in weight. The thickness of each layer can be micron-sized, and the foot pad is light and thin and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of magnetic adsorption wall-climbing robot adsorption systems, in particular to a wall-climbing robot foot pad based on electromagnetic adsorption. Background technique [0002] With the continuous development of science and technology, robots have been widely used in various fields, especially wall-climbing robots, because they can overcome the limitation of gravity and crawl on walls, they have irreplaceable advantages in special environments such as high altitudes and small spaces. As the work tasks and space become more and more complex, wall-climbing robots are also developing in the direction of miniaturization and light weight, so the requirements for the adsorption device of wall-climbing robots are also getting higher and higher. On the one hand, the adsorption device needs to provide sufficient adsorption force; on the other hand, its mass and volume also need to be limited to avoid making the robo...

Problems solved by technology

However, the voltage required by this kind of foot pad is too high, which has certain limitations in practical application; and the foot pad only increases the friction between the robot and the crawling surface, and the robot can only crawl on a surface that is less than 30° inclined. For wall-climbing robots, the adsorption force is small
