A motion simulation of bionic jellyfish based on shape memory alloy

Abstract

Based on the research object of jellyfish, a kind of bionic jellyfish robot driven by shape memory alloy was designed, which could imitate the jet propulsion of the jellyfish. Firstly, the propulsion mode and morphological characteristics of jellyfish are studied. Secondly, the characteristics of shape memory alloy are studied, and the structure for the six leg drive based on shape memory alloy is designed. The driving methods of the shape memory alloy are researched and simulated. Finally, the motion model for jellyfish is studied. Combined with the bell volume of jellyfish change, the movement numerical simulation of the jellyfish results are obtained through software. Compared with three different groups of jellyfish parameters, through motion simulation of jellyfish, the optimal size is selected.
