The world is changing every second continuously, and over the years, Machines has become an integral part of our lives. Technology has changed everything – Our Lifestyle, communication and definitely our perspective also. In this race of evolving technologies, Robots are the race which raised in number over the years.
So, Today we are building a Robot, actually a Line Follower Robot and I will give you step by step guide to make your own robot out from scratch.
Q. – What is a Line Following Robot ?
-:A Line Following Robot or a Line Follower is an autonomous robot which follows either blackline in white area or white line in black area, which depends on the signal received by the sensor and then processed by Microcontroller, which decide the speed and direction of motors.
Q. – How does a Line Follower Work/ Working of a Line Following Robot.
-: A Line Following Robot is a simple robot which do a certain task of following a black line by input sensor.
A basic Line following Robot has 2 IR Transmitting sensor which is made up of an Infrared LED and a Photodiode. The IR LED transmits light rays to the surface and it bounce back from it and catches by the photodiode which then generates a signal and gives it to Microcontroller like Arduino, which processed the signal and then transfer it to Motor driver board which converts the signal into PWM (Pulse Width Modulation) signal which gives the motors the indication to move. The speed and direction depend upon the intensity of light captured and how strong the signal is.
Now that we know, What a Line Follower is and how does it work. So, Now directly jump into the making. In this one, We are not using any Microcontroller. So, Let’s get started.
