After a great long time without working on the project (holidays, back to work and so on), I finally found some time to go on with the next steps.
I've been working a bit more on the "case". As a matter of fact, I hadn't worked on the mechanism that would enable the case to rotate on itself. The electronic part is getting ready, but I had to find a way to garantee that once the gyroscope sends a message to the motor gear, it may rotate the case.
So here we are. The case looks like this :
As we can see, the "eye" is made in plexiglass, and there is a "plate" on top of the box. This is the surface to which we will be attaching the parachute. This plate is attached to the case using a lazy susan, a bit like the one below
Here we see clearly the gap between the plate and the case.
On that example, we see how the lazy susan and the motorized part are linked together
We can see that the lazy susan is attached both to the blue and the green plate
Also, there is an axis that goes throught the lazy susan, and that is attached below the blue plate.
Through the green plate, there is a ball bearing, (below in red) so that the axis turns freely.
Below, there is a structure that holds the gear motor and the two gears, as can be seen below.
We can also see a bearing, in blue, below one of the gear. Thanks to this mecanism, the axis can rotate firmly and yet freely.
I didn't put the engine right below the axis so that it doesn't take the load directly.
Also, there is no reduction factor because the gear motor was choosen to rotate at a maximum speed of 90rpm. I didn't want the engine to run slower for the rotationnal speed I expected.
Also, the V sliders were thought as a plug that would fit in an identical structure attached to the case itself. It's a way to make the engine structure more rigid.
A big thanks to my brother in law Guillaume for the Catia making.
We'll be adding the electronic part & camera to the box in the next steps
