TL;DR: Two newly discovered hydrothermal vent fields, the Dodo and Solitaire fields, which are located in the Central Indian Ridge (CIR) segments 16 and 15, respectively, are reported, with new findings into the biodiversity and biogeography of vent-endemic ecosystems in the Indian Ocean.
Journal ArticleDOI
An on-line adaptation method in a neural network based control system for AUVs
TL;DR: An on-line adaptation method "Imaginary Training" is proposed to improve the time-consuming adaptation process of the original SONCS and is demonstrated by applying to the heading keeping control of an AUV "Twin-Burger".
Journal ArticleDOI
Zero-G Class Underwater Robots: Unrestricted Attitude Control Using Control Moment Gyros
TL;DR: In this article, a novel control scheme based on internal actuation using control moment gyros (CMGs) is developed to provide zero-G class autonomous underwater vehicles (AUVs) with this unique freedom in control.
Proceedings ArticleDOI
Vision based autonomous underwater vehicle navigation: underwater cable tracking
TL;DR: In this article, a vision-based AUV navigation system is proposed and its performance is demonstrated by an autonomous underwater cable tracking (AUCT) mission at Lake Biwa using the test bed AUV "Twin-Burger" available at the University of Tokyo.
Journal ArticleDOI
An adaptive neural-net controller system for an underwater vehicle
Kazuo Ishii,Tamaki Ura +1 more
TL;DR: In this paper, an adaptive neural-net controller system for an underwater vehicle is described and investigated by heading-keeping and path-following experiments in conditions where unpredictable disturbances are applied to the robot.
