Autonomous Underwater Vehicle

The requirement for a more complicated underwater robotic technology that minimize the cost and eliminate the require for human operator and is therefore able of operating autonomously becomes obvious. These requirements lead to the improvement of Autonomous Underwater Vehicles (AUVs). A major problem with autonomous underwater vehicles is being capable to navigate in a normally unidentified environment. The accessible underwater sensor suite have a limited ability to cope with such a navigation difficulty. In put into practice, no single sensor in the underwater environment can offer the level of accuracy, dependability and the coverage of information essential to perform underwater navigation to high degree of  safety.
