YayaBot Line Follow Robot LEGO MindStorms EV3 

12) Robot Follows Black Line - Tutorial.

"Following a line" is a classical problem in robotics. In this tutorial we learn how to teach YayaBot to follow the edge of a black line on a white background, using one colour sensor. It is important that there is a clear distinction in shade between the white background, and the black line itself. This skill has a potential use in many competitions (e.g. RoboCup Junior and First LEGO League).
