Adopting these principles for propulsion had been a challenge some decades ago, but with the current technological progress in robotics, design analysis, advanced computing, precision manufacturing, 3D printing, sensors, actuation, image processing etc have rekindled an interest in this field, especially in the Indian context. Moreover, with the thrust on development of unmanned autonomous systems, especially for the naval warfare, there is a case for looking at an efficient way to propel such vehicles that can stay underwater for a longer duration, move and navigate faster than those traditionally shaped and propelled by screw propellers or pump jets. This paper looks at some of the basics of fish locomotion; technology trends; examples of the current developments; benefits of emerging technologies, investigate performance of some basic shapes of caudal fin of fish with the help of modern analytical tools such as Computational Fluid Dynamics and the way ahead. 000007588 542__ $$fCC-BY-NC-ND-4.0 000007588 6531_ $$aFish 000007588 6531_ $$aFins 000007588 6531_ $$aPropulsors 000007588 6531_ $$aunderwater vehicles 000007588 6531_ $$aRobots 000007588 7001_ $$aRana, R K$$uIndependent Consultant, New Delhi, India 000007588 7001_ $$aJohnson, N$$uCentre for Modeling and Simulation, Savitribai Phule Pune University, Pune India 000007588 7001_ $$aDongare, P$$uCentre for Modeling and Simulation, Savitribai Phule Pune University, Pune India 000007588 7001_ $$aBarve, S$$uCentre for Modeling and Simulation, Savitribai Phule Pune University, Pune India 000007588 773__ $$tConference Proceedings of INEC 000007588 773__ $$jINEC 2018 000007588 789__ $$whttps://zenodo.org/record/2250081$$2URL$$eIsIdenticalTo 000007588 85641 $$uhttps://imarest.org/inec$$yConference website 000007588 8564_ $$95b958f8a-887d-44ae-8bc9-245614058461$$s3804361$$uhttps://library.imarest.org/record/7588/files/INEC%202018%20Paper%20024%20Rana%20FINAL.pdf
