Brick Sorter 8527 (#3)

One of the most popular MINDSTORMS projects is a brick sorting machine, and this is just such a robot. It uses a light sensor to identify the color of a brick: black, grey or white, after which the brick is put in the appropriate bucket. Use the links below for free building and programming instructions. This robot was designed in March 2007.
