PROJECT TOPICResearch Frontiers & Advanced Kinematics
Biomimetic Manta Ray Ocean Glider
A marine bio-robotics research concept studying flexible pectoral fin oscillation, internal oil-bladder buoyancy engines, and hydrodynamic lifting bodies to survey ocean environments with minimal acoustic signature.
Acoustically Silent Marine Bio-Locomotion
- ✓Glides silently through water by flapping flexible pectoral fins like a biological manta ray.
- ✓Changes depth efficiently without motors using an internal variable buoyancy bladder.
- ✓Resists entanglement in marine vegetation due to its smooth hydrodynamic lifting body.
The Engineering Challenge
Problem / Objective
Conventional spinning underwater propellers generate acoustic noise that spooks marine life and can easily tangle in seaweed or abandoned fishing lines.
