When I saw this project, I knew: I wanted to build one! First, it can do something I am not capable of. Second, it involves computer vision, mechanics, some sort of artificial intelligence, and 3D printing. And third: It’s so cool that I can show it to friends and brag about it. What do you want more? I know: It should be easy to build and not too expensive. So, let’s build one. I can’t wait.

Very impressive mechanics - I would have guessed it would require more than two degrees of freedom! I wonder if it could be done self contained using a fixed grid of nine colour sensors (e.g. TCS34725) with all the software running on the microprocessor?

Hi John, He did with his "deluxe" project. But he used a Raspberry with a camera. I assume it is faster than with a single sensor. And you do not need a movement of the sensor. A TCS34725 most probably also would be able to distinguish between the colors.
