A single acoustic beacon-based positioning method for underwater mobile recovery of an AUV
International Journal of Advanced Robotic Systems, 2018 This article presents a navigation method for an autonomous underwater vehicle being recovered by a human-occupied vehicle. The autonomous underwater vehicle is considered to carry underwater navigation sensors such as ultra-short baseline, Doppler ...

A Markov Chain state transition approach to establishing critical phases for AUV reliability [PDF]
, 2011 The deployment of complex autonomous underwater platforms for marine science comprises a series of sequential steps. Each step is critical to the success of the mission. In this paper we present a state transition approach, in the form of a Markov chain,

Optimal Kinematic Control of an Autonomous Underwater Vehicle [PDF]
IEEE Transactions on Automatic Control, 2009 This note investigates the motion control of an autonomous underwater vehicle (AUV). The AUV is modeled as a nonholonomic system as any lateral motion of a conventional, slender AUV is quickly damped out. The problem is formulated as an optimal kinematic control problem on the Euclidean Group of Motions SE(3) , where the cost function to be minimized ...

Optimized Environment Exploration for Autonomous Underwater Vehicles [PDF]
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018 Achieving full autonomous robotic environment exploration in the underwater domain is very challenging, mainly due to noisy acoustic sensors, high localization error, control disturbances of the water and lack of accurate un- derwater maps. In this work we present a robotic exploration algorithm for underwater vehicles that does not rely on prior ...

Tracking multiple Autonomous Underwater Vehicles
Autonomous Robots, 2018 In this paper we present a novel method for the acoustic tracking of multiple Autonomous Underwater Vehicles. While the problem of tracking a single moving vehicle has been addressed in the literature, tracking multiple vehicles is a problem that has been overlooked, mostly due to the inherent difficulties on data association with traditional acoustic ...

Autonomous Underwater Vehicle „ABYSS“ [PDF]
Journal of large-scale research facilities JLSRF, 2016 The Autonomous Underwater Vehicle (AUV) „ABYSS“ is a modular AUV designed to survey the ocean combining geophysical studies of the seafloor with oceanographic investigations of the overlying water column. The basic mission of ABYSS is deep-sea exploration, specifically in volcanically and tectonically active parts, such as mid-ocean ridges.
