A flexible wing and flapping-wing robot

Abstract

The invention relates to the technical field of robots and provides a flexible wing and a flap robot. The flexible wing comprises a first wing body and a second wing body which are symmetric. The first wing body comprises a wing body, a first device and a second device, and the wing body is a wing with an airfoil profile and sequentially comprises an inner wing section and an outer wing section from inside to outside. The first device is a rigid body, is arranged in the inner wing section and can improve the rigidity of the inner wing section of the wing body, and therefore the lift force generation efficiency can be improved. The second device is used for controlling the outer wing section to be bent and deformed and can actively change the flexibility of the outer wing section of the wing body so that the degree of generated thrust can be actively changed, and therefore steering is achieved. Through a reasonable rigidity and flexibility layout, the generation efficiency of lift forceand thrust can be improved, the flexibility controllability of the wing body is achieved, maneuverability is improved, the structure is simple and easy to achieve, and mass application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a flexible wing and flapping wing robot. Background technique [0002] The bionic flapping-wing robot is a new type of flying robot. Its flying principle is different from that of rotor and fixed-wing flying robots. It generates the lift and thrust required for flight by imitating the flapping of bird wings, so as to achieve the purpose of flight. Theoretically, compared with fixed-wing and rotary-wing flying robots, flapping-wing robots have higher flight efficiency and maneuverability, coupled with lower flight noise and bionic appearance, making flapping-wing robots have a wide range of military and civilian applications. The application prospect, and the wing is a key component of the flapping wing robot. By analyzing the wings of various flying creatures, it is found that they are not uniform in thickness, but have a certain airfoil shape, with less flexibility on the inside...

AI Technical Summary

Problems solved by technology

In the prior art, the wings of flapping-wing robots are all formed by simplifying the wings of flying creatures, such as flat wings, passive flexible wings, and double-segment wings. Defects: The lift generated by the planar wing scheme is too small; the passive flexible wing scheme cannot actively adjust the thrust; and the mechanical structure of the double-section wing scheme is too complicated, which is not conducive to popularization and application
