Photo description: This line following robot is made using Lego Mindstorms, a popular robotics kit used by people of all ages. This robot searches for lines using the light sensor and then proceeds to following them using a program designed with the Mindstorms software. The sensor can be seen at the front of the robot, it sends out a light and measures how much of this light is reflected back. Dark colors such as black absorb more light, while bright colors such as yellow and white reflect more. The line following robot sits on a table, resting on its three different types of wheels.
