MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202521109807 A) filed by Vishwakarma Institute Of Technology, Pune, Maharashtra, on Nov. 11, 2025, for 'a biomimetic autonomous underwater vehicle with transformable fin configuration.'
Inventor(s) include Kale, Deep Anil; Gole, Rushikesh Satish; Jadhavar, Prem Prakash; Ghuge, Aditya Balu; Kekan, Swarup Rajendra; Gawande, Anish Nitin; Kale, Pramod K.; and Shirbavikar, Ketki A.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to a biomimetic autonomous underwater vehicle (AUV) with Transformable Fin Configuration designed to optimize performance across diverse marine missions. The AUV comprises a hydrodynamic main body housing, a frame structure, a circular rotation platform, a pivoting linkage system, a central pivot joint, a spherical joint assembly, fin mounting brackets, fin structures, an actuation mechanism, a locking mechanism, and an integrated control system. The fin structures are reconfigurable between two distinct biomimetic swimming modes: a turtle-style configuration with side-mounted fins providing enhanced maneuverability, hovering, and station-keeping at low speeds, and a shark-style configuration with end-mounted fins delivering streamlined, energy-efficient, and high-speed propulsion. Transformation is achieved by disengaging the locking mechanism, actuating the pivoting linkage system through electric motors, reorienting the fins via the spherical joint assembly, and re-locking them in position. This dual-mode propulsion system extends operational versatility, reduces acoustic signature, and eliminates the need for multiple specialized AUVs."
