The "solution" of the simultaneous localisation and mapping (SLAM) problem has been one of the notable successes of the robotics community. SLAM has been formulated and solved as a theoretical problem in a number of different forms. SLAM has also been implemented in a number of different domains from indoor robots to outdoor, underwater, and airborne systems. At a theoretical and conceptual level, SLAM can now be considered a solved problem. However, substantial issues remain in practically realizing more general SLAM solutions and notably in building and using perceptually rich maps as part of a SLAM algorithm. This paper describes the autonomous underwater vehicle (AUV) kinematic and sensor models, it overviews the basic theoretical solution to the extended kalman filter (EKF) SLAM problem, it also describes the way-point guidance based on line of sight (LOS). In this paper, it has been shown through Matlab simulation that the vehicle is able to localize its position using features that it observes In the environment andl at thle same time map thlose features. The vehicle is expected to follow a pre-defined sinusoidal path.
