A biomimetic mechanical insect based on the principle of electrostatic self-excitation

Abstract

The invention discloses a bionic mechanical insect based on the electrostatic self-excited driving principle. The bionic mechanical insect based on the electrostatic self-excited driving principle comprises a framework structure, a row beam structure, a cross beam structure, supporting legs, an electrode structure, a power source and a matched circuit. The framework structure is used for supporting the cross beam structure and the electrode structure; the electrode structure is made of conductive materials and connected with the framework structure. The row beam structure is composed of two or more conductive micro beams side by side, a small carbon fiber piece is attached to one end of each beam, the other end of each beam is fixedly connected with the framework, and the beams are located between two electrodes. The cross beam structure is connected with the supporting legs and connected with the framework structure. The power source and the matched circuit provide adjustable direct current voltage for the two electrodes. The bionic mechanical insect based on the electrostatic self-excited driving principle is simple in structure, light in weight, capable of being microminiaturized easily, and high in energy exchange efficiency.

Description

technical field [0001] The invention relates to a device combining the technical field of micro-electromechanical technology and the technical field of micro-crawling robot, specifically, a bionic mechanical insect driven by DC voltage based on the principle of self-excited vibration of a structure in an electrostatic field. Background technique [0002] Compared with wheeled robots, legged robots have more advantages. They are easier to move in a variety of ground environments and are suitable for performing tasks in small spaces. The mobility and other important parameters of micro-mechanical insects are closely related to the drive system they use. Therefore, the exploration, research and development of the drive system of micro-reptile robots has always been a hot issue in the academic and industrial circles. [0003] The driving system of a micro crawling robot generally consists of three parts: a driver, a transmission mechanism, and a supporting leg. With the advance...

Problems solved by technology

However, its disadvantage is that its high-voltage AC power supply and control circuit cannot be integrated on the robot body due to its complex structure and heavy weight, but can only be externally placed, so that the energy and control signals required for crawling motion can only be conducted through thin copper wires. To the robot, that is, only crawling with wires can be realized
