Suitable Power

The defence, commercial and scientific communities are all aware of the strategic importance that the oceans hold. Future underwater operations are under evaluation using autonomous ocean-ranging submersibles of the unmanned variety. Such vessels are commonly termed autonomous underwater vehicles (AUVs), and the search for suitable power systems that are able to provide high reliability coupled with long underwater durations has intensified over the last decade. This paper presents a review of those power systems that are under consideration, design and development, mainly for the AUV application. No attempt is made by the authors to directly compare individual systems, as this can only be effectively undertaken once a well-defined vehicle and associated mission profile has been defined.

Abstract Unmanned aerial vehicles (UAVs) have become essential tools for exploring, mapping and inspection of unknown three-dimensional (3D) tunnel-like environments which is a very challenging problem. A computationally light navigation algorithm is developed in this paper for quadrotor UAVs to autonomously guide the vehicle through such environments. It uses sensors observations to safely guide the UAV along the tunnel axis while avoiding collisions with its walls. The approach is evaluated using several computer simulations with realistic sensing models and practical implementation with a quadrotor UAV. The proposed method is also applicable to other UAV types and autonomous underwater vehicles.

Submarine inspections and surveys require underwater vehicles to operate in deep waters efficiently, safely and reliably. Autonomous Underwater Vehicles employing advanced navigation and control systems present several advantages. Robust control algorithms and novel improvements in positioning and navigation are needed to optimize underwater operations. This paper proposes a new general formulation of this problem together with a basic approach for the management of deep underwater operations. This approach considers the field of view and the operational requirements as a fundamental input in the development of the trajectory in the autonomous guidance system. The constraints and involved variables are also defined, providing more accurate modelling compared with traditional formulations of the positioning system. Different case studies are presented based on commercial underwater cameras/sonars, analysing the influence of the main variables in the measurement process to obtain optimal resolution results. The application of this approach in autonomous underwater operations ensures suitable data acquisition processes according to the payload installed onboard.
