A network protocol for multiple AUV localization

Oceans '02 MTS/IEEE, 2003
With maturing of AUV technology and underwater acoustic modem technology, networks of AUVs have come into the focus of research on future systems for ocean observation and monitoring. In this paper, we propose a networking algorithm for communication within a group of AUVs deployed on a cooperative mission in an area covering several square kilometers.

Stable Schooling for Multiple Underactuated AUVs

IFAC Proceedings Volumes, 2008
This paper presents a stable schooling scheme for multiple autonomous underwater vehicles (AUVs) where the number of independent actuators for each vehicle are less than the degrees of freedom (DOF). In most of the formation schemes presented so far, the multiple dynamic agents usually have been modeled as particle systems whose motions can be ...

A general control architecture for multiple AUVs

Proceedings of Symposium on Autonomous Underwater Vehicle Technology, 2002
This paper presents a conceptual architecture for the control of multiple autonomous underwater vehicles based on the concept of generalized vehicle. The design of this architecture was driven by requirements extracted from the analysis of operational scenarios involving the operation of multiple vehicles and embodies an extension of the dynamically ...

Formation Control of Multiple Underactuated AUVs

OCEANS 2007 - Europe, 2007
This paper presents a stable formation control scheme for multiple autonomous underwater vehicle (AUV) where the number of independent actuators for each vehicle are less than that of degree of freedom (DOF) of the vehicle's motion. In many of the formation schemes presented so far, the multiple dynamic agents were usually modeled as particles whose ...

Operational Test of Multiple AUVs with an ASV

2018 OCEANS - MTS/IEEE Kobe Techno-Oceans (OTO), 2018
Recently, there is increasing concern about the seabed and demands for surveys of it. Japan has the sixth largest exclusive economic zone area in the world. It is becoming increasingly clear that seabed resources of the exclusive economic zone (EEZ) in Japan can include mineral resources as well as important widely and abundantly distributed energy ...

A cooperative architecture for target localization using multiple AUVs

Intelligent Service Robotics, 2012
A recent concern in marine robotics is to consider the deployment of fleets of autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs). Multiple vehicles with heterogeneous capabilities have several advantages over a single vehicle system, and in particular the potential to accomplish tasks faster and better than a single vehicle ...

A Leader-Follower Algorithm for Multiple AUV Formations

2004 IEEE/OES Autonomous Underwater Vehicles (IEEE Cat. No.04CH37578), 2004
In the future, it may be possible to employ large numbers of autonomous marine vehicles to perform tedious and dangerous tasks, such as minesweeping. Hypothetically, groups of vehicles may leverage their numbers by cooperating. A fundamental form of cooperation is to perform tasks while maintaining a geometric formation. The formation behavior can then

A new method for multiple AUV coordination: a reactive approach

ETFA 2001. 8th International Conference on Emerging Technologies and Factory Automation. Proceedings (Cat. No.01TH8597), 2002
We present a theoretical study of the coordination of the geometrical movements of one flotilla of autonomous underwater vehicles. We make the assumption that the flotilla must move by respecting geometrical constraints of forming which we indicate by the term of geometrical constellation. Under this hypothesis, every vehicle has to follow a trajectory

Tracking and Formation for Multiple AUVs with Time Delay

2021
Many ocean missions require one or more AUVs. However, due to the time-variant communication delay, the implementation of tracking task is more challenging. In this chapter, the problems of single single-vehicle tracking and multivehicle tracking are studied. With consideration of time-variant communication delay, two model-free PD tracking controllers
