Line Follower Robot.

It is an Arduino controlled vehicle that follows a line, either a black line on white surface or vise-versa. In this tutorial, we will teach you to make the line follower robot move on the line. The main electronics components that will be used in making this line follower robot are two sensors made by using IR Proximity sensors, L293D as motor driver circuit, Two DC motors and battery.

We have used IR Transmitters and IR receivers to direct the positions. It will sense black  or white surface. we can control the motor speed and direction through L293 driver circuit. All program coded in Arduino Mega board.

These robots can also be used as automatic cars running on roads with embedded magnets.These can also be used at homes for domestic purposes like floor cleaning etc.These can be used in public places like shopping malls, museums etc to provide path guidance.

Components/Modules Required:-

  1. L293 Motor Driver Module.
  2. Arduino Mega 2560.
  3. 2 IR proximity sensor
  4. Batteries.
  5. 2 DC motors

Mechanical Components/Modules Required:-

  1. Acrylic sheet
  2. Caster wheel.
  3. 2 wheels.
  4. Metal Chassis.
