First claim

1 . A hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction, comprising:
a fish head module, the fish head module comprising a fish head shell, wherein the fish head shell is internally provided with a rigid exergonic reaction bin, a combustible agent storage unit for injecting combustible gas into the rigid exergonic reaction bin, a combustion promoter storage unit for injecting an accelerant into the rigid exergonic reaction bin, and an exergonic excitation device for exciting chemical exergonic reaction in the rigid exergonic reaction bin, and a rigid push plate is in sliding fit in the rigid exergonic reaction bin; a fish body module, the fish body module comprising a flexible fishbone connected to the rigid push plate in a matched mode, restraint assemblies arranged at two sides of the flexible fishbone, and flexible fish skin wrapping the flexible fishbone and the restraint assemblies, wherein front ends of the restraint assemblies are connected to the fish head shell, and the flexible fishbone is capable of generating a post-buckling phenomenon when rapidly pushed by the rigid push plate; and a fishtail module, the fishtail module comprising a fishtail fixing block for being connected to the flexible fishbone and rear ends of the restraint assemblies.

2 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein each restraint assembly comprises a plurality of transmission parts hinged in sequence.

3 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 2 , wherein each transmission part comprises a deformation auxiliary block, a hinge shaft arranged at one end of the deformation auxiliary block, and a hinge sleeve arranged at the other end of the deformation auxiliary block; and adjacent transmission parts are hinged through the running fit of the hinge sleeve and the hinge shaft corresponding to each other.

4 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 3 , wherein the flexible fish skin is capable of simultaneously generating a post-buckling phenomenon along with the flexible fishbone through the deformation auxiliary block, and then the flexible fish skin is capable of being deformed to an initial state due to elastic recovery.

5 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 4 , wherein a post-buckling reaction module is composed of the fishbone fixing block and the rigid push plate, and the fishbone fixing block and a side wall of the fish head shell provide fixed restraint for the occurrence of the post-buckling phenomenon.

6 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein the fish head shell is further internally provided with a head control bin, the combustible agent storage unit, the combustion promoter storage unit and the exergonic reaction excitation device are all arranged in the head control bin.

7 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein the fish head shell is provided with a bionic swim bladder and a bionic gill, both of which control the buoyancy of the robot through water absorption or drainage.

8 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein the fish head shell is provided with an optical imaging module for detection.

9 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein the fishtail module further comprises a fishtail imitation piece arranged outside the fishtail fixing block.

10 . The hairtail-imitating high-speed soft robot driven based on chemical exergonic reaction according to claim 1 , wherein the flexible fishbone gradually decreases in longitudinal cross-sectional area from front to back.
