Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1-4 shown.

[0026] A multi-combination propulsion type flexible bionic robot fish, which is mainly composed of a fish head 1, a fish body, a fish tail 6 and various fish fins, such as figure 1 As shown, the fish head 1 is composed of a fish body artificial muscle 2 with flexible electrodes, a flexible skeleton 3 and a flexible shaft 14, as figure 2 shown. Flexible shaft 14 and some annular frame shapes (similar automobile steering wheel structure, such as figure 2 ) The flexible skeleton 3 constitutes the robotic fish skeleton structure 13 of the present invention. The fish body artificial muscles 2 are symmetrically distributed on both sides of the flexible skeleton 3 and installed between two adjacent ring-shaped flexible skeletons 3 in a tensioned state. The fish body artificial muscle 2 is a dielectric type electroa...

Abstract

A multi-combination push type flexible bionic robotic fish comprises a head, a body, a tail and fins. The multi-combination push type flexible bionic robotic fish is characterized in that the body comprises a flexible shaft, flexible skeletons and body artificial muscles with a flexible electrode, the flexible skeletons are of an annular frame structure and is fixed to the flexible shaft, the body artificial muscles are symmetrically arranged between the flexible skeletons in a tensioning state, when the artificial muscles on one side are powered on, the tensile stress is reduced, and the artificial muscles on the other side contracts, so that the flexible shaft and the body bends continuously, and are matched with the tail and the fins to form the body/fin push mode; the head and the tail are arranged at the two ends of the flexible shaft respectively and are connected with the first flexible skeleton and the last flexible skeleton respectively. The flexible structure and flexible drive are adopted, the multi-combination push type flexible bionic robotic fish simulates the motion function of bionic fishes to form gradient flexible shape changing of the whole robotic fish, the flexible body/tail fin push mode and the flexible middle fin/pair-fin push mode are achieved, and movement is flexible.

Description

technical field [0001] The invention relates to a bionic technology, in particular to a bionic robot fish, in particular to a multi-combination propelling flexible bionic robot fish driven flexibly by artificial muscles. Background technique [0002] Fish is the earliest vertebrate that appeared in nature. After hundreds of millions of years of natural selection, it has evolved extraordinary water sports functions. Compared with ordinary underwater propellers, fish swimming has the characteristics of high efficiency, high maneuverability, low disturbance, and strong adaptability to complex environments. [0003] At present, scientists at home and abroad are exploring efficient and flexible underwater propulsion methods that are different from propeller propulsion. The bionic robot fish studies the propulsion mechanism of fish, and can be used in water quality monitoring, military reconnaissance, underwater rescue, underwater archaeology, marine life observation, underwater ...
