Deep Sea Underwater Robotic Exploration in the Ice-Covered Arctic Ocean with AUVs
(IEEE, 2008-09-22)
The Arctic seafloor remains one of the last unexplored areas on Earth. Exploration of this unique environment using standard remotely operated oceanographic tools has been obstructed by the dense Arctic ice cover. In the ...
Recent Advances in Synchronous-Clock One-Way-Travel-Time Acoustic Navigation
(IEEE, 2006-09-18)
This paper reports recent results in the development
and deployment of a synchronous-clock acoustic navigation
system suitable for the simultaneous navigation of multiple
underwater vehicles. The goal of this work is to ...
Experimental Results in Synchronous-Clock One-Way-Travel-Time Acoustic Navigation for Autonomous Underwater Vehicles
(IEEE, 2007-04-10)
This paper reports recent experimental results in the development and deployment of a synchronous-clock acoustic navigation system suitable for the simultaneous navigation of multiple underwater vehicles. The goal of this ...
Underwater Acoustic Navigation with the WHOI Micro-Modem
(IEEE, 2006-09-18)
The WHOI Micro-Modem is a compact, low-power
acoustic transceiver that can provide both acoustic telemetry and
navigation. Its size and versatility make it ideal for integration in
autonomous underwater vehicles (AUVs). ...
A New Autonomous Underwater Vehicle for Imaging Research
(IEEE, 2000-09-11)
Currently, unmanned underwater vehicles either
tend to be cumbersome and complex to run, or operationally
simple, but not quite suitable platforms for deep
water imaging. Aware of the currently existing capabilities
of ...
BathyBoat: An Autonomous Surface Vessel for Stand-alone Survey and Underwater Vehicle Network Supervision
(2010-08)
Exploration of remote environments, once the domain of intrepid adventurers, can now be conducted in relative safety using unmanned vehicles. This article describes the joint University of Michigan (UMich) and Michigan ...
Large Area 3-D Reconstructions from Underwater Optical Surveys
(IEEE, 2009-04)
Robotic underwater vehicles are regularly performing vast optical surveys of the ocean floor. Scientists value these surveys since optical images offer high levels of detail and are easily interpreted by humans. Unfortunately, ...
Exactly Sparse Delayed-State Filters
(IEEE, 2005-04-18)
This paper presents the novel insight that the SLAM information matrix is exactly sparse in a delayed-state framework. Such a framework is used in view-based representations of the environment which rely upon scan-matching ...
Visually Augmented Navigation in an Unstructured Environment Using a Delayed State History
(IEEE, 2004-04-26)
This paper describes a framework for sensor fusion
of navigation data with camera-based 5 DOF relative pose
measurements for 6 DOF vehicle motion in an unstructured
3D underwater environment. The fundamental goal of this ...
PhotogrammEtric Models for Marine Archaeology
(IEEE, 2006-09-18)
The paper presents a method to create small scale
topographic models of a deepwater archaeological site using
photogrammetric methods. An example data set from a
Norwegian archaeological investigation is discussed.
