A Unified Approach for Underwater Homing and Docking of over-Actuated AUV

Journal of Marine Science and Engineering, 2021
During the implementation of time-consuming tasks such as underwater observation or detection, AUV has to face a difficult and urgent problem that its working duration is greatly shortened by the limited energy stored in the battery device.

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,

Intervention AUVs: The Next Challenge [PDF]

IFAC Proceedings Volumes, 2014
While commercially available AUVs are routinely used in survey missions, a new set of applications exist which clearly demand intervention capabilities. The maintenance of: permanent underwater observatories, submerged oil wells, cabled sensor networks, pipes and the deployment and recovery of benthic stations are a few of them.

Visual Navigation for Recovering an AUV by Another AUV in Shallow Water [PDF]

Sensors, 2019
Autonomous underwater vehicles (AUVs) play very important roles in underwater missions. However, the reliability of the automated recovery of AUVs has still not been well addressed. We propose a vision-based framework for automatically recovering an AUV by another AUV in shallow water.
