DYNAMICS AND SIMULATION OF BIOROBOTIC UUV

Mechanics, 2013
This paper describes a dynamics model of a biorobotic unmanned underwater vehicle (UUV). And a new accurate model for calculating fluid dynamics of flapping hydrofoil is also incorporated into the simulation. The model is used to simulate the motion of the biorobotic UUV which used a compressed body propelled by four flapping hydrofoils.

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly
