Abstract

Bionic robot fish (Body and/or Caudal fin (BCF)) is a bionic robot fish propelled by Body and/or caudal fin (BCF). It has the advantages of high speed, efficiency and high mobility, and is the focus of bionic robot fish development in recent years. In this paper, skipjack bonito with crescent caudal fin and swimming pattern of Jacks was selected as biomimetic object. By collecting the body proportion and characteristics of skipjack bonito, the overall shell design of the bionic robot fish was carried out, and a multi-degree of freedom and multi-joint caudal fin was designed to realize various underwater movements of the robot fish.
