Abstract

Navigation using active beacons has been with us for many centuries. For mobile robot, laser, sonar and radio are common media for navigational beacons. An autonomous mobile robot with infrared beacon has been developed in this project. The transmitter, which is mounted on the beacon, transmits infrared signals. The robot is equipped with a three infrared receiver that will detect infrared signals from beacon as the target of robot navigation placed in anywhere within a limited range and finally robot will navigate to the beacon autonomously. The beacon will emit infrared signal continuously until the robot reach the beacon. This robot that can react autonomously with the environment without depending on human. PIC16F877A has been used as a microcontroller for this robot. PIC 16F877 A has an internal built in analog-to-digital (ADC) which was used to convert optical signal that received by infrared receiver to electrical signal.
