Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] This embodiment provides a piezoelectric ceramic flapping wing robot, which uses piezoelectric ceramic material as a power source, and has two motion modes of land walking and flapping wing flight, and has strong adaptability to the environment.

[0026] The robot includes a pair of wings, a fuselage support frame 6, a transmission amplification mechanism 3, a piezoelectric ceramic bimorph 7, a head support block 4, a universal ball support rod 5, a drive cable 12 and a pair of drive feet.

[0027] Wherein the fuselage support frame 6 is a left-right symmetrical plate structure made of ABS material, and its head is hollowed out to reduce the weight of the fuselage and reduce the air resistance during flight. Transmission amplifying mechanism 3 comprises active rod 13, two connecting rods 15 and two driven rods 14; The centerline of the body support...

Abstract

The invention discloses a piezoelectric ceramic flapping-wing-type robot. The piezoelectric ceramic flapping-wing-type robot comprises a robot body support frame, robot wings, a piezoelectric driver, a driving electric cable, a transmission amplifying mechanism and driving feet, wherein the robot wings are based on a bionic design and are similar to a dipster hoverfly in shape; when the robot walks on land, a piezoelectric ceramic sheet is selected as the piezoelectric driver, and the piezoelectric ceramic sheet and a single-bent-end transmission amplifying mechanism form the driving feet; the driving electric cable inputs two common grounding sine wave signals for respectively driving the two driving feet, and the robot is driven to do controllable plane motion by utilizing a resonant oscillation principle. When the robot flies in the sky, the driving feet are taken down; a piezoelectric ceramic bimorph element is used as the piezoelectric driver to input a driving voltage signal; by a four-connecting-rod transmission mechanism, the oscillation is amplified and is converted into flapping of wings, thereby driving the robot body to fly. The robot is simple, light and convenient, and has certain adaptability to the environment.

Description

technical field [0001] The invention relates to a piezoelectric ceramic flapping wing robot, which belongs to the technical field of robots. Background technique [0002] In recent years, more and more researchers at home and abroad have discovered the research value and feasibility of micro flapping wing robots, and the technology of micro flapping wing robots is gradually becoming mature. [0003] The flapping wing robot can take off in situ and hover in the air, and is suitable for performing tasks under long-term no energy supplement and long-distance conditions, and has broad application prospects in military and civilian fields. It has received great attention from many countries including the United States, Japan and the United Kingdom. The traditional flapping wing robot uses a micro motor as a power source, which has a complex structure and high power consumption. Piezoelectric ceramics, as a functional ceramic material capable of converting mechanical energy and ...
