Swimming Performance of a Tensegrity Robotic Fish

Soft Robotics, 2019
Abstract We described a tensegrity robotic fish and detailed its overall structure, stiffness, and mechatronics. The main flexible structure of the robotic fish body was composed with a series of rigid segments linked with tensegrity joints by means of tension elements.

Mimicry of fish swimming patterns in a robotic fish

2012 IEEE International Symposium on Industrial Electronics, 2012
This paper 1, presents a novel approach for realizing Carangiform fish swimming patterns by a robotic fish. A video recording system is first set up to capture real fish behaviors. From robotic perspective, three basic Carangiform fish swimming patterns, “cruise”, “cruise in turning”, and “C sharp turning”, are extracted.

Fish-Tail Modeling for Fish Robot

2012 International Symposium on Computer, Consumer and Control, 2012
Derivation of the mathematical model for a robot fish considering forward motion and yaw angle kinematics is presented. This model also includes details of the hydrodynamic force by considering the condition of fish swimming underwater. The nonlinear dynamical model in Carangi form locomotion type is derived by use of Lagrange's equation, which ...

Study of artificial fish bladder system for robot fish

2011 IEEE International Conference on Robotics and Biomimetics, 2011
The robot fish, with straight and turn movement, is undertaken by the waving of body combined with caudal fins. In heaving motion, fish robot is propelled and controlled by pectoral fins or a changing system like the bladder in real fish. In this paper, the adjusting gravitation method was chosen to change the depth of sinking and make robot fish ...

On the Efficiency of Robot Fish

2007 Chinese Control Conference, 2006
Fish swimming have the characteristic of the high efficiency, low noise and high flexibility. And more researchers draw attention to robot fish and obtain considerable achievement. This paper focused on the efficiency of the robot fish. Through the analysis of the robot fish's dynamical model, the relationship between the speed of Robot fish and the ...
