Today the students built and programmed a robot that would follow a line.
The giant white paper had a wide black line printed on it.
The robot would follow the circular line forever.
(Well, until the batteries would completely drain).
The students used a light sensor to detect when the bot was over a light area or a dark area.
This triggered one of two motors to go forward. In effect, this makes the robot follow the line.
