A survey on Navigation Systems in Dynamic Environments

Mobile robot navigation is a method of guiding a robot to accomplish a mission through an environment with obstacles in a good and safe manner. The main challenge of current mobile robotics is to develop intelligent navigation systems, where autonomous navigation is a research focus that aims to give a machine the ability to move in an unassisted environment, without human intervention to accomplish the desired goal. The task of navigation is to give the robot the opportunity to obtain the information it needs to reason and equip it with a locomotion capacity adapted to its environment. However, it implies complex systems in the realization, where their control poses important problems not only technological but also scientific. An autonomous mobile robot is a mechanical system that must be able to make decisions to perform movements based on information about its position and the environment in which it operates. The problem addressed in this article is that of autonomous navigation in a dynamic environment "The objective is to study models and computer techniques allowing a mobile robot to move autonomously, that is to say without intervention in an uncertain environment and in the presence of obstacles.
