Now-a-days, every robot functions with the help of the microcontroller, and hence the circuit is too complex to understand. For this reason, the Line follower robot is developed with a simple concept. This robot is a mobile automation robot which follows white line on a black surface or black line on a white surface. In this present scenario, often accidents on the roads occur due to careless driving of drivers. This line follower robot can reduce the chance of accidents to a great extent and it quite economical for transportation.
