What is a Line Follower ? A line follower is an autonomous robot that can follow a line on the arena. The line is usually black or white in color with a contrasting background. The most basic arena consist of a closed loop containing curves as shown below. The more advanced arena will consist of junctions , diversions, splits in track and inversion of the color of the line. How to tackle the problem The robot will have to sense the line and change its trajectory using the information received. The most simplest method is to have two sensors and a differential drive. When the right sensor has detected a line the right motor stops, thus effectively producing a turning motion , which continues till both the sensors are again in the white region. This way the robot follows the line. Design The various parts of the system are Chassis Motors Wheels Sensors Power Source Chassis The body of the robot should be sturdy and easily workable . The different options include plywood, GI sheet and PVC foam sheet. Out of these the PVC foam sheet is the most effective in terms of workability and strength and is available in small quantities at a reasonable rate. The design of the robot will mainly depend on the size constraint and the specific requirements of the event. While designing keep in mind any future expansions and provide space for every component like the batteries. PVC foam sheet can be easily drilled and connected using nut and bolts. Motors The different motors that are commonly used for ro
