AUV : r2d4 Summary The Autonomous Underwater Vehicle r2d4 was constructed in 2003. r2d4" inherited the software and functions from its predecessor "R-One Robot". But compare to "R-One Robot", r2d4" is half a length, and a quarter of weight, and its function is much superior as it is capable to be operated from a small vessels. Moreover, with its excellent intelligence, it can navigate underwater in accordance with the preprogrammed course. And it also can fix the survey course by itself when it collects the abnormal data from the surroundings. Max depth rating: Dimension: Weight in air: Speed: Endurance: Power Primary items 4000m L4.4m B1.1m H0.8m 1630 kg 3 kts 60km (12 hrs) Rechargeable Lithium Ion Battery
AUV : AQUA EXPLORER Series Summary "Aqua Explorer" Series is the small Autonomous Underwater Vehicle (AUV) for tracking of submarine cables. It is expected to be used for survey of the condition of buried cables, searching for the fishery resources, and extensive survey of underwater environment. "AE2000"is the advanced vehicle of "AE2". "AE2000" has twice endurance of AE2 and can dive to 2000m.
