Modelling, Analysis and Application of Biomimicry of Fish

Abstract

Biomimetics or biomimicry is the emulation of the systems, ele-ments and models of nature for the in order to solve complicated problems. There are various biomimetics model which are developed for various opera-tions like underwater explorations, water pH detection, to check the pollution level of water, etc. This report is mainly focused of designing of fish geome-try for rescue operation. Based on the movement of real fishes, a tail me-chanical structure for fitting a carangiform of fish body wave motion is de-signed. Co-ordinating the motions of the pectoral fins and tail fin, the robotic fish can simulate the motion of real fishes in water. Basic understanding of components required for developing fish swim motion are studied. Finally, the CAD model of fish is presented followed with the simulation and prepa-ration of primary prototype.
