This book focuses on designing a mobile robot’s navigation system. More specifically, it considers the challenges of designing and operating a mobile search robot used to search for, find and relocate a target object in an indoor environment. A step-by-step mobile robot construction approach guides us in the design and implementation of a mobile robot. This work proposes construction methods for two different types of mobile robots. For exploration of a path, we will develop an algorithmic strategy known as a ‘bug navigation’, in which, the robot navigates by following the walls or obstacle boundaries. The most common object detection and recognition techniques are presented in a simple style. This book also helps one to develop an efficient way to identify the location and orientation of a robot with an effective mechanism of control.
