Now a day's Robotics is a emerging technology which reduces the effort of humans. The concept of Mobile Robot is fast evolving and the number of mobile robots and their complexities are increasing with different applications.. There are many types of mobile robot navigation techniques like path planning, self -localization and map interpreting. The project is to build a mobile robot which avoid obstacle and to plan its moment. It has an infrared sensor which is used to sense the obstacles coming in between the path of ROBOT. It will move in a particular direction and avoid the obstacle which is coming in its path. AnInfrared ray sensor is used to detect the obstacle and send information to controller and after processing the input microcontroller redirects robots using motors which are controlled by motor drivers.
