Today we met in order to successfully complete several aspects of our misssion.
final triggering mechanism is composed of a servo motor whose rotation is
converted into a linear vertical movement of the Vacuette, which is guided
through a mounting. This conveyance is ensured by a fixed split pin. The
interaction can be compared to the mechanism of an engine relating to the
mechanism of a crankshaft and a connecting rod. The Vacuette is then to be
broached by the cannula. In order to seal the Vacuette, the servomotor rotates
in the counter direction. To ensure the stability of the system, the cannula is
fixed in both vertical directions. A sufficient force exerted by the servomotor
is necessary as the membrane is quite hard to be pushed through. This is what we were about to test today. It is proven that the exerted force is enough. The vacuette moved 0.53 cm what it satisfying as this is a
distance we can work with very well. Nevertheless, we modified the servomotor
so that it is able to turn 360 degrees and can cover a distance of about 1 cm,
even though the opening angle it is not aligned perfectly in the direction of
Due to the realization of our final triggering mehanism, we were able to completely finish the 3D-mounting of our CanSat. It is going to be printed tomorrow. Aftwerwards, the several components are to be fitted into the can. In case they cannot be perfectly placed into the mounting due to measuring inaccuracies, the 3D model is to be modified.
