Concepts will be presented as well as the development of analytical model and qualitative model of the sensor; for the local localization, in the case of strategy reactive by reflex movement, for a mobile robot navigating in the unknown and dynamic environment. The use of these concepts is then illustrated by simulation examples simulating the evolution of the robot in various environments are presented which show, that the most significant problem being, the optimization of the time taken by the robot between perception and the corresponding action. The reactive strategy system, can fixe the direction of the target in a cluttered indoor environment without scanning this environment.]]>Abdelmoudjib, K.,1999Habib, M.K.,2007Benoit, E. and L.
