Development of Autonomous Underwater Vehicles ; A brief overview

Autonomous Underwater Vehicles are characterized by the usage of state of the art technology, such as powerful embedded controllers, vast arrays of sensors, and advanced robotic systems. From the early years building underwater vehicles to the latest developments, there has been an increasing interest in the potential applications of these marine platforms. Oceanographers, oil companies, and even naval associations have found in the autonomous underwater vehicle an opportunity to explore the deepest parts of the oceans. This growing interest has triggered different efforts around the world to design and develop unmanned underwater vehicles. The purpose of this paper is to describe and provide an overview of the benefits, challenges and risks of using autonomous systems for ocean exploration. Furthermore, the article describes the main components involved in the correct operation of an autonomous underwater system.
