Future view of advanced investigation and construction work in port area

Abstract

The importance of investigation and construction of port facilities is to increase in the future. Mechanization of both investigation work and construction work is necessary for safer and more efficient underwater work. We are studying Towed AUVs and Amphibious Walking Robots for investigation work and Teleoperated Underwater Backhoes and Underwater Grasp Machines for construction work. Each machine is used not only separately but also coordinated having geographic data in common by underwater GIS. To obtain positional data, we are also studying Precise Ultrasonic Positioning Technology.
