A four-degree-of-freedom beetle-like micro-flying robot with foldable flapping wings

Abstract

The invention provides a four-degree of freedom beetle-imitated foldable flapping-wing micro flying robot, and solves the problem that a flapping-wing micro air vehicle in the prior art does not achieve flapping wing folding, rear wing outward expanding / adduction action and a self-locking function. The four-degree of freedom beetle-imitated foldable flapping-wing micro flying robot comprises a four-plate folded wing module, and the four-plate folded wing module is connected with a rear wing bracket module; and the rear wing bracket module, a rear wing outward expanding / adduction action driving module, a rear wing folding driving module, a pitching driving module and a wing flapping driving module are mounted on a cable-driven module mounting bracket. The four-degree of freedom beetle-imitated foldable flapping-wing micro flying robot has the advantages that motion performances of the beetle-imitated flapping-wing flying robot are improved; the technical scheme that the flexible cable drive technology and spring sheets are combined is adopted, so that the folding rate and folding reliability of folded wings are remarkably improved; the rear wing outward expanding / adduction action and the self-locking function are designed, so that the flying robot is more conveniently carried and hidden in complex environments and has wide application prospects; and besides, modular design is adopted in structure, so that the flapping-wing micro flying robot has larger expansion spaces in structure and motion functions.

Description

technical field [0001] The invention relates to a bionic robot, in particular to a four-degree-of-freedom micro-flying robot imitating a beetle with foldable flapping wings. Background technique [0002] In recent years, flapping-wing MAV technology has developed rapidly. The beetle's hind wings have attracted many researchers to study folding wings because of their large folding rate. For example, the area of ​​the rear wing of the genus is four times larger than that of the folded wing. Compared with fixed-wing and flapping-wing aircraft, the bionic foldable-wing aircraft has a smaller physical size, which is easy to carry, conceal, and camouflage to adapt to complex environments. And to meet different tasks, the micro flapping wing aircraft has important application prospects in the military and civilian fields, and the research on the bionic design of its flexible folding wings is of great significance. [0003] At present, there are many kinds of flapping-wing micro-ai...
