Use TensorFlow and Raspberry Pi to Build an Automatic LEGO Sorter #piday #raspberrypi @Raspberry_Pi

Via Hackster.io:

You know the problem: all of those LEGO kits you’ve bought over the years eventually end up all mixed up in a big tub. Before long, you’ve got a bin full of thousands of different kinds of bricks, and finding any specific kind of brick is like searching for a needle in a rainbow stack of needles. Fortunately, Paco Garcia has developed a solution, and you can follow his lead to build your own automatic LEGO sorter with TensorFlow running on a Raspberry Pi.

Garcia was inspired to build his LEGO sorter after seeing how a Japanese farmer used TensorFlow to sort cucumbers. The basic concept is straightforward: a camera takes a photo of a LEGO brick, and then TensorFlow determines what kind of brick it is. The brick is then placed in a bin with others of its kind. Of course, actually executing that concept was a big challenge, and Garcia’s automatic sorting machine took a lot of mechanical engineering skill.
