On This first week we looking for some documentation, or project that already exist.

We didn't find a lot of it, only two of them were interesting :

                                                                - Project for a submarine closer to a real-life mode (DIY)
                                                                - A Lego submarine

The first one is really interesting with the pump system and the balance. The other one was more compact and

We decided to take a couple of ideas in the both project. The balande system of the first one and the pump system ( with the seringue ) of the Lego project.

We also make some sketches to have an idea of the size

For the next week we will have to find a tube, in preference a transparent tube to see how the submarine works. Also make some research for the buoyancy.
