In this paper research has been carried out to develop a navigation technique for an autonomous robot to work in a real world environment, which should be capable of identifying and avoiding obstacles, specifically in a very busy a demanding environment. In this paper better technique is develop in navigating mobile robot in above mention environment. The action and reaction of the robot is addressed by fuzzy logic control system. The input fuzzy members are turn angle between the robot head and the target, distance of the obstacles present all around the robot (left, right, front, back).The above mention input members are senses by series of infrared sensors. The presented FLC for navigation of robot has been applied in all complex and adverse environment. The results are hold good for all the above mention conditions
