Abstract

The invention discloses a rigid-flexible coupled frog-like robot driven by explosion, which belongs to the field of soft jumping robots. The problem of uncontrollable jumping posture, landing direction and unstable landing of the existing soft bouncing robot is solved. The invention utilizes the principle of hydrogen and oxygen detonation and energy release, and combines the combination of soft detonation cavity and rigid piston type constraints to realize the release of energy, and can convert chemical energy into mechanical energy in a short period of time, and can realize relatively large instantaneous At the same time, the expansion direction of the soft explosion chamber can be controlled through rigid piston constraints, so that the jumping direction and attitude of the robot can be controlled. The invention is applicable to 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...
