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.
