![]() ![]() These LED / LDR pairs detect the black line on the white surface on which the robot is supposed to move. The sensor part consists of a set of LED / LDR pairs for the left side and right sides. The line following robot can be divided into several blocks, as shown in Fig.2:įig.2 Block Diagram for Line Follower Robot Section 2 describes about the sensors, section 3 describes about the comparator, section 4 describes about the motor driver, section 5 describes about the Dc motor and wheels, section 6 describes about the chassis and body structure. Organization: The paper is organized in the following sections. They usually ask robotic teams to build a small robot with specific dimensions and weight. There are many annual line follower robots competitions organized by universities or industries around the world. This kind of robot can be used for transportation systems, blind assistive applications, military purposes, delivery services. ![]() A group of comparators and a motor driver circuit can do the duty. It is not required to use microcontroller for this type of mechanism. The line follower mechanism conferred here is meant to follow a black line on a white background. The sensors that can be used are typically LED/LDR, LED/Photodiode or LED/Phototransistor pairs. The path consists of a black line on a white surface. The line follower is a self-operating robot that detects and follows a line that is drawn. Line follower robots are used in semi as well as fully autonomous plants. Now a days industries are highly automated for various applications. Key words: Line Follower, Sensor, Manipulator, Magnetic field, Comparator. Line follower robots were one amongst the earliest automatic target-hunting robots. The path can be a black line on white surface or vice-versa or it can be invisible like a magnetic field. Line follower is a machine that can follow a path. It is a system that contains power supplies, sensors, manipulators, control systems, and software, all working together to perform a task. A robot is a machine design to execute one or more tasks repeatedly with speed and precision. ![]() Prananjali Koppad, Vishnu Agarwal Telecommunication Engineering Department, Dayananda Sagar College of Engineering, BangaloreĪbstract:- Robot is an invention of modern times. ![]()
