AUV experiments in obstacle avoidance
Proceedings of OCEANS 2005 MTS/IEEE, 2005Reactive obstacle avoidance (OA) is an important step in attaining greater autonomy in autonomous underwater vehicles (AUV). For AUVs that conduct underwater surveys, avoidance of uncharted obstacles can improve vehicle survivability. This paper discusses initial experiments at the Center for AUV Research in obstacle detection and avoidance using the ...

MobiL-AUV: AUV-Aided Localization Scheme for Underwater Wireless Sensor Networks
2016 10th International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing (IMIS), 2016In this paper, we present the mobile autonomous underwater vehicle (AUV)-aided efficient localization scheme for underwater wireless sensor networks (UWSNs). Localization is one of the major issues in UWSNs as it is important in some large scale applications to know the accurate position of sensor nodes.

Control-oriented modelling of a hybrid AUV
2010 IEEE International Conference on Robotics and Automation, 2010This paper introduces a control-oriented model for a class of autonomous underwater vehicles (AUVs) characterized by an actuation system that includes propellers, internal weight motion and ballast charge/discharge. Since this kind of actuation combines the actuation of both oceanic gliders and self-propelled AUVs, these vehicles are termed hybrid ...

Balloon AUV: Seawater Sampling AUV Using Active Buoyancy Control
2018 IEEE/OES Autonomous Underwater Vehicle Workshop (AUV), 2018A significant amount of waste has been thrown into the ocean, and the debris from the waste has been sunken into the deep sea. So we proposed an autonomous underwater vehicle to collect water-quality data in deep water and sample water in the area which pollution level is high.

OCEANS 2006 - Asia Pacific, 2006
In this paper we discuss automatic processing necessary to provide to the AUV more autonomy for analysis and decision, to allow it to re-plan its trajectory in order to increase the efficiency of its MCM operation. Results of Automatic Detection and Classification. (ADC) applied on Synthetic Aperture Sonar (Sas) images is presented.

Robust diving control of an AUV
Ocean Engineering, 2009Mobile systems traveling through a complex environment present major difficulties in determining accurate dynamic models. Autonomous underwater vehicle motion in ocean conditions requires investigation of new control solutions that guarantee robustness against external parameter uncertainty.

2015 IEEE/OES Acoustics in Underwater Geosciences Symposium (RIO Acoustics), 2015
This paper shows the preliminary perceptions of pipeline inspection with AUV (Autonomous Underwater Vehicle) in oil and gas fields. The intent of this new technology is to increase productivity and reduce costs related to facilities inspection. The AUV used is a Kongsberg HUGIN 1000 equiped with Synthetic Aperture Sonar (SAS), Multibeam echosounder ...
