Development of quad-rotor type underwater robot for fixed-point observation

Abstract

Ocean development has actively progressed in the sea near Japan. However, in marine research, it is impossible for people to work in deep sea because of low temperature, high pressure and so on. We have developed the underwater robot that mimics the quad-rotor helicopter in the past. This robot is capable of performing freely exercise of translation and rotation by controlling the rotational speed of the four rotor.
