UNDERWATER ROBOT

摘要

This underwater robot is provided with: a frame; a propulsion unit; a weight; a buoyant material; and a drive mechanism. The propulsion unit has a plurality of propellers that generate propulsion force in each direction of a first axis, a second axis, and a third axis which are orthogonal to each other. The weight is attached so as to be movable in the direction of the first axis and the center of gravity of the weight is moved through movement thereof in the direction of the first axis. The buoyant material is attached so as to be movable in the direction of the second axis and the buoyancy-center position of the buoyant material is moved through movement thereof in the direction of the second axis. The drive mechanism respectively moves the weight and the buoyant material in the direction of the first axis and in the direction of the second axis in synchronization with each other.
