Hello!
Finally my entry is done:

It's a pneumatic submarine. I wanted to make something similar to the 8868 B model (which is the best B of all time imho), but 200 parts aren't much for that. So I decided to make a pneumatic sequencer base, which allows an automatic function circuit. Working method: two pneumatic cylinder are connected to the other's valve, they control each other. The big cylinder controls the two small. :

So the main function is the pneumatic arm, other smaller ones are described in this picture. Video is available below.
Made with 200 parts:

Thanks to the outer shell with the yellow panels, the submarine is pretty rigid:

I know, there isn't much time left to the end of the contest, but in the last few weeks I was very busy. Fell free to ask or comment, I'm courious about your opinion.
