Autonomous navigation of underwater vehicles

IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002
The goal of the work is to propose a method to solve with visual means the problem of underwater navigation of an autonomous vehicle moving in deep sea in order to perform inspection of a pipe positioned near the ocean floor. We refer to the ability of an autonomous system to determine its motion with respect to the environment. It is well known that a

Cooperative Autonomous Underwater Vehicle localization

OCEANS'10 IEEE SYDNEY, 2010
Due to some communication constraints of the underwater environment, cooperative localization for AUVs is a hard task. In this paper, we present the state of the art in this area, analyse the existing solutions to related problems and propose 2 algorithms, based on the EKF, to solve the localization problem with a group of Autonomous Underwater ...

Underwater Navigation Systems for Autonomous Underwater Vehicle

2018
Over the past few decades, researchers, navy of different countries and different organizations related to maritime archaeology, underwater mines & pipelines etc. had paid considerable attention towards underwater surveying & inspection by autonomous robot or vehicle. Considerable improvements for better AUV navigation have seen in different sensors in

Autonomous Underwater Vehicle Systems

1997
Abstract : The long-term goal is to understand the physical and biological relationships often requires high resolution sampling far exceeding present capabilities. If spatially adaptive sampling can be developed, data resolution can be greatly improved over that presently possible with conventional sensor platforms.

Navigation of underwater autonomous vehicles

Proceedings of the 2000 International Symposium on Underwater Technology (Cat. No.00EX418), 2002
The paper suggests an approach to solving the problem of navigation of an underwater vehicle using acoustic and geometric data and gravitation field potential changing in time. The known methods of making seafloor acoustic maps are not effective for correction of coordinates in areas of smooth relief and in shallow water. The suggested algorithm allows

Autonomous Underwater Vehicle Docking

2016
This chapter describes the practical challenges of docking autonomous underwater vehicles (AUV s) in the ocean environment and approaches undertaken to create working docking systems. Early docking work was motivated by the desire to operate AUVs for multiple sorties without recovery or human servicing of the AUV. To accomplish this, the docking system

The autonomous underwater vehicle "Pipsqueak"

Oceans '02 MTS/IEEE, 2005
A team of freshman students was presented with the ambiguous challenge of designing an AUV (autonomous underwater vehicle) the size of a wallet. A Micro-AUV would be small enough to avoid many of the transport problems. Because of the potentially simple design of such an AUV, purchase and maintenance costs could be kept fairly low.

Multiple communicating autonomous underwater vehicles

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
This paper addresses the problems associated with missions using multiple cooperating autonomous underwater vehicles. In such missions, inter-vehicle communication is an important requirement upon which coordination strategy and intelligence decision making functions can be built.

Autonomous underwater vehicles

2018
usc Refereed/Peer-reviewed The chapter deals with the development of indirect adaptive controllers based on Fuzzy Control approach for Autonomous Underwater Vehicles (AUVs). The non-linear, coupled and time-varying dynamics of AUVs necessitates the development of adaptive controllers.
