Line Follower Robot with Obstacle Avoiding Module

The line robot which we are trying to make is a robot which can sense a line(usually black) with the help of its IR sensors and walk on the path which is to be made by the line which can be modified by the user to get his work done with the help of the robot. It does so with the help of the microcontroller board by arduino which is arduino UNO which will be more than sufficient for our project. The microcontroller (Arduino UNO) inputs the signal from the IR sensor and then analysis the signal and give instructions to its dc motors whether to start the left motor or right motor or both of them. We will also introduce an ultrasonic sound sensor which would be used to detect the obstacles and change its path and get back to its line again. There will be 3 IR sensors for the line follower robot to be more accurate. The centre IR sensor will be on the black line and whenever there is a left turn, the left sensor will be on the black line and the left motor will stop and right one will move the robot towards the left and similar would be the working for a right turn. Whenever all the three sensors of the robot will sense the black line the robot will stop.
