This paper describes the development result of an underwater walking robot CR200. The CR200 is 6- legged seabed walking robot designed to work in high current and low visibility environment. The along sectional shape of the body is streamlined to improve the hydrodynamic characteristics. In order to detect the disturbance from the current, we installed an acoustic Doppler current profiler (ADCP), an attitude heading reference system (AHRS) on the body and a contact force sensor on each foot. Acoustic camera and scanning sonar were installed for the inspection of the low visibility environment. The pressure canister and electric-driven six legs/arms guarantee the 200m pressure-resistant and watertight performance. The main frame was made of carbon fiber reinforced plastic (CFRP) in order to reduce the total weight. In this paper, we introduce the results of manufacturing and verify the design concept.mlined to improve the hydrodynamic characteristics.
