Line Follower and Obstacle Detector Robot
Abstract To construct a Line Follower & Obstacle Detector Robot based on a group of Integrated Circuits. A pair of IR Emitter & Receiver is used to guide the intelligent system throughout the track. Data from the sensing arrangement is feeded to the OP-AMP (LM-324), which is further feeded to the AND IC (IC-7408) for conditioning. The conditioned data is then directed to the motor driver IC (L293D) to drive the gear motor. Introduction: Robotics has become a very common application in most of the developed countries. High performance, high accuracy, lower labor cost and ability to work in hazardous places has put robotics in an advantageous position over many other technologies. The main idea of this project is to design and build an autonomous line following robot, which is capable of following a white line drawn on a black surface. It has an infrared sensor system and logic gates to guide the robot along the black line. The black line and white surface is detected by the IR s...
