NXT Dominosorter
My first project with the NXT (old one). I was always annoyed when anyone has a "Domino Day" and all the colours where mixed, so I made this sorter.
About this creation
My first project with the NXT (old one). I was always annoyed when anyone has a "Domino Day" and all the colours where mixed, so I made this sorter.

The principle is very easy:
You have an undercarriage with a turntable and upon it is the mechanism.


Step 1: If you run the programm, you first have to push on the push-sensor.


Step 2: The first motor will then pull one domino out of the storage and under the light-sensor.










Step 3: The light-sensor measures the reflected light and so gets to know which colour it is.



Step 4: The second motor turns the whole upper part till the right position, which has been determined by the light-sensor.





Step 5: Then, the third motor turns the plate under the light sensor and the domino falls down.





Step 6: At last the whole thing goes back to its start position and starts again with the first step.





And these are some side- and upviews:




Now I will never have to sort domino's by colour!

Quoting Family Vuurzoon Hi Techno Moves, Great technical solution for a an annoying domino problem! How many colors does it recognize?
It is hard to separate two colors like blue and green, so I think he can recognize 4 colors!
