The Obstacle Avoiding Line Follower Luggage Carrying Robot can be used in airports for boarding the baggage of passengers and will reduce human haphazard in airport management. It is a Photodiode and Sonography Technology based autonomous robot, which can be used in Airports. This self-explanatory machine generally follows the predefined line drawn on the floor, which is a high contrasted black colour line on a white surface or a white colour line on a black surface. If an obstacle comes in its following line, it can detect it by emitting ultrasonic sound waves. This sound wave measures the distance by the reflection and avoids the obstacle by converting the gleamed wave into an electrical signal and continues following the line using radiation-sensitive optoelectronic components. This paper presents the design and construction of a small Obstacle Avoiding Line Follower Luggage Carrying autonomous Robot based on Arduino UNO R3 SMD Microcontroller, L298N Motor Driving Shield, LM393 Chipped Infrared Sensor, HC - SR04 Ultrasonic Sonar Sensor and Direct Current (DC) Motor. In this experiment, the robot will detect its trajectory with a spectral sensitivity in the infrared wavelength signal to the microcontroller. If an obstacle blocks the trackway, the burst of ultrasounds will detect it with echo to turn the robot to avoid and will follow its route again. Throughout this experiment, the design of hardware orientation and software operation for the robot’s mobility is explained with construction. The eminent idiosyncrasies can also be used for future industrial and domestic robots, which will be capable of completing tasks with complex functionality without getting stuck for obstacles.
