Abstract

The bionic machine fish with shape memory alloy wire for swinging forward is one kind of robot. The bionic machine fish includes one rigid head, and one propelling tail fin mechanism comprising one tail and at least one swinging joint. Each of the swinging joint includes one elastic sheet, shape memory alloy wires fixed on two sides of the elastic sheet, and one elastic covering. Two adjacent swinging joints are connected through a base plate, and so do the rigid head and the first swinging joint. The present invention has the advantages one small size, simple structure, good bionic effect, no noise and convenient operation.

Description

technical field

[0001] The present invention relates to a robot. Background technique

[0002] The bionic robot fish refers to the propulsion mechanism of fish swimming, and uses machinery, electronic components or intelligent materials to realize the underwater propulsion function. The wide application of bionic fish in marine exploration, pipeline detection, military and entertainment has made its research more and more in-depth, and the characteristics of some intelligent materials (such as shape memory alloys) have made it possible to develop high simulation, low Noise-based bionic fish offers a new way of thinking.

[0003] According to the physiological parts and propulsion principles on which fish swim, fish can be divided into two categories: BCF and MPF, BCF—caudal fin (body and / or caudal fin), this type of fish mainly relies on the body MPF—median and / or paired fin (median and / or paired fin), these fish rely on the pelvic fin in the middle of the body to swim. ...
