In day to day life human friendly mobile robots are achieving great popularity. As these robots are making human life easier, their demand is increasing day by day. There are many kind of indoor mobile robots developed which are used in different sectors like hotels, hospitals, airports and for the household work. To obey any further instructions or to move smoothly into given environment a mobile robot must know its current location. So this paper mainly focuses on finding indoor mobile robot’s location. For this purpose a RFID (Radio frequency identification) technique is being used. Basically this technique is identification technique but due to its enormous features, from last ten years this technique has been used for the localization purpose also. Again indoor environment may contain different obstacles that must be avoided by the robot while roaming. So for this purpose infrared sensors are used which will detect the obstacle and avoid collision by changing its path.
