Hydrodynamic Performance of Soft Robotic Fish Actuated by Ionic Polymer-Metal Composite Pectoral Caudal Fin

Abstract Soft robotic fish has a lot of benefits. This paper aims to create with soft pectoral caudal fin which was powered by IPMC material. The fish’s hydrodynamic performance during straight swimming is numerically computed using the overset grid approach. Compared tail driven driving frequency 0.05 Hz and those together three fins different frequencies amplitude, coefficients pressure bionic are analyzed. We can find regions distinct positive negative flapping. And forward component provides propulsion for fish. greater flapping is, smaller amplitude drag force receives. It concluded that while Hz, 5.64 mm, effect good. Further research into how affect capabilities also made.
