Locust bounce imitation robot driven by memory alloy

Abstract

The invention discloses a locust bounce imitation robot driven by memory alloy, which comprises a thigh structure, a shank structure, memory alloy springs, an energy storage torsion spring and a reset structure; the thigh structure consists of a support plate and support rods which are fixed at the two sides and the tail end of the support plate; the shank structure comprises a shank plate and supporting femora; the memory alloy springs are fixed at the two sides of the thigh structure; the front ends of the memory alloy springs are connected with the top of the shank plate through a heat insulation line; one end of the energy storage torsion spring is fixed with the front end of the thigh structure while the other end of the energy storage torsion spring is hinged with the top of the shank plate; the reset structure comprises a micro motor which is fixed at the bottom of a thigh support plate; a coil disc is fixed on a power output shaft of the motor; coil posts are arranged on the coil disc; a coil is fixed on one of the coil posts; the coil penetrates through a guiding hole on the thigh support plate so as to be fixed with median femora of shanks; upper femora of the shanks areprovided with elastic hooks; the thigh support plate is provided with a chute which is matched with the hooks in the aspect of end size; and the size of the tail part of the chute is increased to release the hooks buckled with the chute.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a locust-like bouncing robot driven by a memory alloy. Background technique [0002] At present, the research on jumping robots is still in the laboratory stage in the world, and only a few colleges and universities in my country have carried out research on related topics in recent years. Advantages, it can cross obstacles that are several times or even dozens of times higher than its own height. It has flexible movement and high work efficiency. Especially in interstellar exploration, since the surface gravity acceleration of the moon and Mars is lower than that of the earth, it can make full use of the bouncing movement With this advantage, a higher jumping height can be achieved to overcome obstacles on the surface of the planet. [0003] Bionic robot is a robot with efficient movement developed by technicians in order to improve the movement ability of the robot, inspired by t...
