If you do not have this, we have explained how to build one yourself. Block Diagram of the Project The line follower robot built in this project is divided in to 4 blocks. The following image shows the block diagram for line follower robot. Block Diagram Description Sensors (IR Sensor) : We have used IR Sensor Module as the line detecting sensor for the project. It consist
