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.
