Design Framework and Motion Control for Biomimetic Robot Fish

Proceedings of the 2005 IEEE International Symposium on, Mediterrean Conference on Control and Automation Intelligent Control, 2005., 2005
This paper deals with the design and 3D motion control of a radio-controlled, multi-link and free-swimming biomimetic robot fish based on an improved kinematic propulsive model. The performance of the robot fish is determined by the fish's both morphological parameters and kinematic parameters. By ichthyologic theories of propulsion, a design framework

Generation of robotic fish locomotion through biomimetic learning

2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012
This paper presents a novel biomimetic learning approach for a Carangiform robotic fish to learn swimming locomotion. A video recording system is first set up to capture real fish behaviors that are used as the training samples. Three basic Carangiform swimming motion patterns, “cruise”, “cruise in turning” and “C sharp turn”, are extracted from ...

An Experimental Study on the Fish Body Flapping Patterns by Using a Biomimetic Robot Fish

IEEE Robotics and Automation Letters, 2020
This letter presents an experimental study on how different body flapping patterns affect the performances of fish cruising. First, a biomimetic robot fish is designed and built as the experimental platform, which mimics the skeleton structure and the muscle arrangement of real fish. Moreover, an improved Central Pattern Generator (CPG) is developed to

Biomimetic Design of a Soft Robotic Fish for High Speed Locomotion

2020
We present a novel DC motor driven soft robotic fish which is optimized for speed and efficiency based on experimental, numerical and theoretical investigation into oscillating propulsion. Our system achieves speeds up to 0.85 m/s, outperforming the previously reported fastest free swimming soft robotic fish by a significant margin of 27%. A simple and

System and Experimental Research on Biomimetic Robot Fish

2007 International Conference on Mechatronics and Automation, 2007
To realize fish-like robot swimming behaviors poses tremendous challenges, especially for the realization of fish body. This paper highlights the system design and experimental research of a free-swimming biomimetic robot fish. By propulsive theories, a design scheme concerning with both physical realization and control methods is presented, where ...

Design of a free-swimming biomimetic robot fish

Proceedings 2003 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM 2003), 2004
This paper is concerned with the design of a radio-controlled, 4-link and free-swimming biomimetic robot fish based on a simplified kinematic propulsive model. The robot fish uses a flexible posterior body and an oscillating foil as a propulsor. The speed of the fish's swimming is adjusted by modulating joint's deflections.

Analytical control design for a biomimetic robotic fish

2011 IEEE International Symposium on Industrial Electronics, 2011
In this paper, the modeling and control of a biomimetic robotic fish is presented. The Anguilliform robotic fish consists of N links and N−1 joints, and the driving forces are the torques applied to the joints. Considering kinematic constraints, Lagrangian formulation is used to obtain the dynamics of the fish model.

Dynamic Modeling of Three-Dimensional Swimming for Biomimetic Robotic Fish

2006 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2006
This paper presents a three-dimensional, dynamic model of robotic fish which synthesizes both the carangiform and anguilliform swimming modes. The designed robotic fish is composed of three parts: stiff anterior body with a pair of pectoral fins for up-and-down motion, flexible rear body, and an oscillating lunate caudal fin.

Hydrodynamic optimization of a relative link lengths for a biomimetic robotic fish

2011 15th International Conference on Advanced Robotics (ICAR), 2011
This paper focuses on the robotic fish body shape and mechanical design optimization problems. We show that our methodology will allow finding costs and benefits of having different number of links and the length of these links. We provide an algorithm of finding optimal lengths of links of robotic fish body.
