Design and implementation of an intelligent robotic fish

Abstract

In the field of underwater exploration, bionic robotic fish are more useful than autonomous underwater vehicles as they have better propulsion ability and fluid adjustability. In this paper, a new method is proposed for the design of an intelligent robotic fish with a 6 degree-of-freedom (DOF) mechanism and equipped with underwater vision for tracking. With its specially designed caudal and pectoral fins, the robotic fish has excellent swimming capabilities either in remote control or automatic control mode.
