Negative pressure-static composite bio-robot adsorption device and method

Abstract

The invention discloses a negative pressure-static composite bio-robot adsorption device and method. The device comprises a static membrane, an elastic membrane and an elastic pressure plate arrangedin turn, wherein the elastic membrane provides flexibility and support for the whole adsorption device; a static generation module, a one-way valve body, a link pipe and a vacuum pump are arranged onone side of the elastic pressure plate; a sucking disc is arranged on one side of the static membrane; the sucking disc is arranged at the center of the static membrane; the bottom of the sucking discis fixed on the elastic pressure plate; the bottom of the sucking disc is connected with one end of the link pipe through the one-way valve body; the other end of the link pipe is connected into thevacuum pump. The method is as follows: the static generation module is fixed on the elastic pressure plate, the static membrane provides static adsorption force by use of the high-voltage static generated by the static generation module and provides sealing for the sucking disc to obtain greater negative-pressure adsorption force; while the negative-pressure adsorption generates negative-pressureadsorption force, the distance between the static membrane and the adsorbed object is further shortened, and greater static adsorption force is obtained. According to the device and the method provided by the invention, stable and rapid landing of an unmanned aerial vehicle can be realized on the surfaces different in roughness.

Problems solved by technology

Chinese patent (CN 102390528, application date 2011-10-21) discloses a micro-robot that flies in the air and absorbs in all directions. The negative pressure adsorption device used in it has certain limitations. Gas will reduce the vacuum in the adsorption chamber, thereby reducing the adsorption force

In addition, as an adsorption method, electrostatic adsorption has relatively small adsorption force, good flexibility, and can adapt to rough surfaces. However, it needs to be continuously attached to the surface to obtain greater adsorption force. harsh
