Development of Fin Propelled Unmanned Underwater Drone

Abstract

The development of Unmanned Underwater Vehicle (UUV) in the recent decade has opened new applications in navy and marine platforms. UUV is either autonomous or radio-controlled robots that can operate underwater without a human occupant. Manoeuvrability must be considered with higher priority during the development stage of the drone. Any vehicle that mimics biological organisms has better performance and efficiencies. The UUV being fabricated is propelled with the help of two adulatory fins inspired by the locomotion of rays and cuttlefish and will be controlled wirelessly. Each fin mechanism is comprised of individually actuated fin rays, which are interconnected by an elastic membrane. An on-board microcontroller is used to generate the motion pattern that results in fin undulations which propels the UUV. The designed hull portion consists of electronic components with leakage proof and also holds the fin. An attempt has been made to develop the UUV with improved manoeuvrability and performance features.
