This book discuses two methods of works for contribution to mobile robotic system projects. The main contribution deals with the problems of Simultaneous localization and Mapping of an autonomous mobile robot in unknown indoor environments that are used in different applications. Navigation and mapping method in an indoor environment in main contribution based on the behavior of the robot that has been developed for fully automatic navigating by using wall following technique theory with building 2D map for indoor environment by using sonar sensors and also used encoders to determine the...
