Passive Localization for Multi-AUVs by Using Acoustic Signals

Proceedings of the International Conference on Underwater Networks & Systems, 2019
In order to maintain a desired formation of multiple autonomous underwater vehicles (multi-AUVs), one important task is to localize all AUVs. This paper addresses a passive localization method which uses the acoustic signals from the support ship and their own.

Multi-AUV coordination in the underwater environment with obstacles

OCEANS'10 IEEE SYDNEY, 2010
A concept of extended formation which is derived by combining the destination and obstacles in the underwater environment as elements into the traditional formation of AUVs is proposed. In extended formation, an improved potential-field-based approach is introduced to coordinate multiple autonomous underwater vehicles (AUVs).

Multi-AUV Coverage with Functional Constraints and Currents

2020 IEEE/OES Autonomous Underwater Vehicles Symposium (AUV)(50043), 2020
Many underwater survey applications such as bathymetry archaeological, mine-counter-measure surveys, etc., can be efficiently performed using autonomous underwater vehicles (AUVs). In all the mentioned survey applications, a region of interest needs to be covered using some sensors. Low cost AUVs have shown promise to perform these applications quickly

Heterogeneous Multi-AUV Aided Green Internet of Underwater Things

ICC 2021 - IEEE International Conference on Communications, 2021
Autonomous underwater vehicles (AUVs) have been envisaged as a key enabler for empowering the Internet of Underwater Things (IoUT) networks to address the challenge of ever-increasing demand of ocean exploration. However, the energy constraint of AUVs' movement makes it challengeable to obtain full-space movement and extravagant information exchange ...

A maximum entropy method for multi-AUV grouping

Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005
A vector-quantization formulation is used to define a grouping problem for multiple AUVs in a sampled environment. The objective is to minimize a quantization error function. The self-organizing network structure developed by Kohonen is a famous quantization model.

Multi-AUVs for Visual Mapping Tasks

2008
The present paper describes a system for the construction of visual maps (“mosaics”) and motion estimation for a set of AUVs (Autonomous Undersea Vehicle). Robots are equipped with down-looking camera which are used to estimate their motion with respect to the seafloor and to built real-time mosaic. As the mosaic increases in size, a systematic bias is

Maintenance and transformation method for a multi-AUV dense formation

Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering
Accurate formation maintenance and safe formation transformations are significant challenges for multiple autonomous underwater vehicle (multi-AUV) dense formations. To address these problems, an innovative control method for a multi-AUV dense formation is proposed.

Task Allocation of Multi-AUVs Based on Innovative Auction Algorithm

2017 10th International Symposium on Computational Intelligence and Design (ISCID), 2017
Based on task allocation of multi-AUV (Autonomous Underwater Vehicle) system, the innovative auction algorithm is applied to hunting task assignments of multi-AUV. The two most decisive factor in the auction algorithm: the election of the auctioneer and the calculation of bidding value.

Coordinated control for multi-AUV systems based on hybrid automata

2007 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2007
This paper presents a coordinated control strategy based on hierarchical control architecture for a team of Autonomous Underwater Vehicles (AUVs). The dedicated control structure is described by a four layered design for coordinated control, constituted with a global organizer and a local organizer modeled by a discrete-event system as two upper layers,
