Docking experiment of underwater vehicle by dual-eye visual servoing in sea

open access: yesNihon Kikai Gakkai ronbunshu, 2017
A variety of robots has been studied and developed for undersea exploration. One of the applications for undersea exploration is mining of undersea resources such as methane hydrate and rare metal by Autonomous Underwater Vehicle (AUV).

Hydrothermal Chimney Distribution on the Endeavour Segment, Juan de Fuca Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The Endeavour Segment of the Juan de Fuca Ridge is well known for its abundance of hydrothermal vents and chimneys. One‐meter scale multibeam mapping data collected by an autonomous undersea vehicle revealed 572 chimneys along the central 14 km of the ...

Modeling and Simulation of Cross-Rudder Underactuated AUV Based on Kane Dynamics

open access: yes水下无人系统学报, 2023
In order to obtain a more accurate dynamics model of autonomous undersea vehicles(AUVs), the kinematics and dynamics equations of the cross-rudder underactuated AUV were deduced by introducing the related knowledge of Kane dynamics.

Waypoint-tracking Control of a Benthic AUV Based on Model-free Adaptive Control Method

open access: yes水下无人系统学报, 2022
In this study, the model-free adaptive control(MFAC) method was applied to a waypoint-tracking control system to solve the problems of high uncertainty in the marine environment and difficulty in accurately determining the benthic autonomous undersea ...

Bistatic seabed scattering measurements from an autonomous undersea vehicle [PDF]

open access: yesProceedings of Meetings on Acoustics, 2012
A bistatic seabed scattering measurement technique is described using a towed source (1600-3500 Hz) and towed array in close proximity to the seabed probing vertical angles from 6-20o and bistatic angles from 126-160o. The data strongly support sediment volume scattering as the mechanism that controls the seabed scattering at 2400 Hz across the entire ...

Grid-based GA path planning with improved cost function for an over-actuated hover-capable AUV [PDF]

open access: yes, 2014
For an AUV to perform a long-range mission with its maximum endurance, its energy consumption during transit must be kept to a minimum. This paper presents an improved cost function for a grid-based genetic algorithm (GA) path planning in 2D static ...

Vertical water velocities from underwater gliders [PDF]

open access: yes, 2010
The underwater glider is set to become an important platform for oceanographers to gather data within oceans. Gliders are usually equipped with a conductivity/temperature/depth (CTD) sensor, but a wide range of other sensors has been fitted to gliders ...

Nonlinear optimization of autonomous undersea vehicle sampling strategies for oceanographic data‐assimilation [PDF]

open access: yesJournal of Field Robotics, 2007
AbstractThe problem of how to optimally deploy a suite of sensors to estimate the oceanographic environment is addressed. An optimal way to estimate (nowcast) and predict (forecast) the ocean environment is to assimilate measurements from dynamic and uncertain regions into a dynamical ocean model.
