Piezoelectric ceramic flapping-wing-type robot
TLDR
In this article, a piezoelectric ceramic flapping-wing-type robot is described, where the robot body support frame, robot wings, a driver, a driving electric cable, a transmission amplifying mechanism and driving feet are used to enable the robot to fly.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.read more
