ABSTRACT:
A submersible vehicle is a type having swinging wings. The vehicle is provided with a vehicle main body, a plurality of swinging wings provided for the main body and arranged in series, rotatable shafts located at front edges of the swinging wings, respectively, actuators for driving the shafts independently of one another, and a wing controller for controlling the actuators in such a manner that the wings enable to swing in a flexible manner like the tail fin of a fish, thereby producing a desired propelling force and performing a steering operation.
