This simple light following robot consists of a minimum number of components: two transistors, four resistors, a photo resistor, LED and a motor. Of course, this all is required for driving only one motor so you need to multiple these components by two so that your robot can move left and right - towards a light source.
There are more versions of this robot and here is another one which we have all seen earlier. Check the video of robot in action.
