In the next tutorial, students will be able to find an illustrated explanation of how to program the robot to follow a line. However, it will be best if you initiate a discussion on the topic before reading the material. Talk about different approaches that could be used, what the possible challenges that one may face are, etc. Usually, students will easily reach the conclusion that the robot should go forward if on black and turn towards the line if on white. Try to explain to them that in such cases it will be impossible for the robot to know if it should turn left or right and that is the reason why we do not follow the line, but its edge.
