Abstract

The invention discloses a fire blast driven rigid-flexible coupling frog-imitating robot, and belongs to the field of soft jumping robots. The problems that the jumping posture and the landing direction of an existing soft bouncing robot are uncontrollable, and landing is unstable are solved. The explosion energy release principle of hydrogen and oxygen is applied, energy release is achieved in the mode that the soft explosion cavity and rigid piston type constraint are combined, chemical energy can be converted into mechanical energy in a short time, the large instantaneous acceleration of the robot can be achieved, and meanwhile through rigid piston type constraint, the expansion direction of the soft body burning and explosion cavity is controlled, so that the jumping direction and posture of the robot are controlled. The fire blast driven rigid-flexible coupling frog-imitating robot is suitable for the technical field of bionic robots.

Description

technical field [0001] The invention belongs to the field of soft jumping robots. Background technique [0002] Soft jumping robots have broad research prospects in the field of robotics. Compared with traditional rigid robots, soft robots require higher complex environment adaptability, higher bionic potential, higher lightweight potential and higher safety of human-computer interaction. [0003] Existing soft bouncing robots include frog-like underwater soft robot flexible explosion fracturing devices and drilling strings driven by chemical release energy reactions, and a magnetically driven jumping soft robot based on magnetically programmed temperature-sensitive hydrogel. The main disadvantages of these soft robots are low instantaneous acceleration, poor controllability of energy release direction, etc. [0004] The deflagration reaction has the characteristics of extremely fast reaction speed, a large amount of heat release, and a large amount of gas generation, so t...
