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 ...

The use of computational fluid dynamics to assess the hull resistance of concept autonomous underwater vehicles [PDF]

, 2007
Autonomous Underwater Vehicles (AUV’s) provide an important tool for collecting detailed scientific information from the oceans depths. The hull resistance of an AUV is an important factor in determining the powering requirements and range of the vehicle.

A theoretical approach to facilitating transition phase motion in a positively buoyant autonomous underwater vehicle [PDF]

, 2009
Positively buoyant autonomous underwater vehicles (AUVs) operate at survey speeds with a pitch angle that ismaintained through application of the control surfaces, sufficient to generate hydrodynamic forces to counteract theexcess buoyancy. To facilitate

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 ...
