Intellectual Property India Publishes Patent Application for 'Adaptive Dead-Reckoning Enabled Biomimetic Underwater Robotic Fish System With Hybrid Communication And Environmental Monitoring' Filed by Mohan Babu University

MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641063515 A) filed by Mohan Babu University, Tirupati, Andhra Pradesh, on May 19, for 'adaptive dead-reckoning enabled biomimetic underwater robotic fish system with hybrid communication and environmental monitoring.'

Inventor(s) include Mr. Dhanireddy Veda Phanindra Reddy; Mr. K. Deshik Reddy; Mr. A. Giridhar; Mr. J. Siva Prasad; Ms. Bhavya Thiyyari; and Dr. M. Dharani.

The application for the patent was published on May 29, under issue no. 22/2026.

According to the abstract released by the Intellectual Property India: "The present invention discloses a biomimetic underwater robotic fish system (100) configured for underwater exploration, environmental monitoring, and surveillance applications. The system comprises a waterproof fish-shaped housing structure (102), propulsion assembly (104), controller unit (106), sensor module (108), navigation module (110), communication module (112), power supply module (114), and adaptive trajectory correction module (116). The propulsion assembly generates oscillatory fish-like movement using servo-actuated tail motion for hydrodynamic underwater propulsion. The sensor module acquires underwater depth, temperature, orientation, and visual information using pressure sensors, temperature sensors, inertial measurement units, and camera modules. The navigation module estimates underwater position through dead reckoning calculations based on inertial sensing data. The adaptive trajectory correction module improves localization accuracy using Kalman filter-based sensor fusion and acoustic beacon recalibration. The communication module enables hybrid acoustic and satellite communication for underwater and surface-level data transmission. The invention provides improved underwater navigation accuracy, reduced hydrodynamic disturbance, real-time environmental monitoring, and scalable deployment capability for marine exploration and surveillance applications."
