“…It allows the researchers to reproduce with control to evaluate the behaviour of real fish Faria et al (2010), or in learning natural evolution and other biological assumptions referred by Long et al (2011Long et al ( , 2006. More recently Marras and Porfiri (2012) and Raja Moahemd and Raviraj (2015) robotic fish have shown that tethered robot with moving caudal fin able to form schooling behaviour similar to natural fish inside tank. When the tail fin was not moving, then natural fish did not react for schooling to support the assumptions that a bio-mimetic robot can aid in reading behavioural aspects.…”

Robotic fish design is an upcoming and interesting research area with lot of challenging tasks due to the impulsive dynamics of water space. In this paper an evolutionary computational approach is performed to design caudal fins under carangi form and sub-carangi form swimming modes. Size and Shape with SOLEIL and multi-body evolutionary experiments were carried out using Euler-Lagrangian equation-based BhT tool to experiment and validate the hydrodynamic effects of caudal fin by avoiding complex and time consuming CFD simulations to achieve realistic motion. To improve average velocity of robotic fish two approaches have been suggested, one is a hill climbing algorithm to find optimal shape with standard stiffness whereas the second approach considers both shape and stiffness together in a genetic algorithm. Finally simulated fin models are compared against physical models to identify the correlation and performances of both to accurately approximate real world performances in a simulated environment leading to design optimised caudal fins for robotic fish.

Robotic fish design (Biomimetic) is an upcoming research area in which undulation motion has its own set of parameters to decide its efficiency. To analyse its swimming efficiency several existing robotic models using undulation motion have been thoroughly studied and few critical parameters such as fin size, shape, flexibility of material, fin flapping rate etc., have been identified. After simulating the above critical parameters using a MATLAB based CFD tool, mainly to design prototypes for research purpose which concentrates on optimizing its swimming efficiency. Several combinations of critical parameters are discussed for robotic fish prototype design by identifying critical parameters and maximizing the swimming efficiency of robotic fish based on the above properties. The fin models have been tested using Matlab based CFD tool through simulation and the swimming speed, direction have also been tested for various models. An improved benchmark for designing robotic fish model is proposed in order to simplify selection of components, architecture, and cost involve.

Submerged robots are broadly acclimated in the acreage of amphibian development. The necessity for higher value and propulsive routine basically requires fish-like performance. Fish swim in an unusual motion such as ostraciiform. The Ostraciiform pond approach utilizes the caudal fin aerial to accomplish piscine propulsion with axis maneuverability. Various absolute automatic angle models based on oscillatory motion has been studied. Such as the sensors, actuators, accouterments and software used. Structures and abstracts acclimated in absolute angle robots and acceptation of alternative is reviewed. It helps in allotment of appropriate set of ambit to structural design of prototype fish for analysis purposes.
