I always wanted to work with robotics. I just dont know where to start. One day I find about this robot. It is pretty familiar to all. So I dont want to make you bore by explaining all the thing.

In case you don’t know what is LINE FOLLOWING ROBOT is, it’s a robot that can follow a line automatically. The line should be darker on lighter floor or vice versa. Like black line on white floor.


I also add an extra feature that it can avoid any obstacle in its path.



We use ATtiny26 microcontroller as our robots brain. The robot can detect the line by Infrared Sensor. We use five sensors.
