Today we build Line follower robot without using Arduino or any microcontroller, by simply using this easy to build DIY kit.
A line follower robot is an autonomous robot which follows a black line line on a white background. The circuit of this Robot is very simple. It uses some photoresistors, a comparator chip, and some transistors in order to drive the motors. In the future we are going to build more advanced robots using Arduino or Raspberry pi in order our robot to be more “smart”. But this robot is a first good start!
