... of continuing disturbance forcing self-propelled model to float. Consequently, depth control in this condition seems to be more difficult. In addition, the state of self-propelled model's is unsteady because of surface capture when it dives from the surface into the deep water. In order to solve problems above...

... After the vehicle of 10,000m class ROV KAIKO had lost in May, 2003, JAMSTEC has developed 7,000m class ROV KAIKO7000 and started scientific dives in April, 2005. The performance of KAIKO7000 had been insufficient compared with the lost vehicle because it had remodeled compact ROV UROV7K...

..., an underwater vehicle, which can dive to the deepest ocean and work in there, is effective and practical. Currently, however, there is no such vehicle in the world. So, Japan agency for Marine-Earth Science and Technology (JAMSTEC) started to develop a new ROV as an Advanced Sediment Sampling System...

... ABSTRACT Kaiko has been the only one full ocean depth survey system in the world since 1995. She has accomplished more than 20 dives to 11000 m at Challenger Deep in the Mariana Trench. Unfortunately, in May 2003, the secondary cable of the Kaiko was snapped during 296th dive at a depth...
