High-Level Project Summary
A release/decoupling device has been developed to separate space modules, light, resistant, small, reusable and that does not use any pyrotechnic mechanism, thus avoiding considering security protocols in this regard. It uses a close and release mechanism with ordinary bearings, energy storage elements and lubricated parts that allow a smooth disengagement and avoiding the shocks and vibrations typical of devices that use pyrotechnic mechanisms, shape memory alloys and metal joints that break through temperature.

Space Agency Data
Basically we have consulted the documentation offered by NASA for this particular challenge, especially the explanatory video that makes clear the idea that it was necessary to develop a small device that would avoid unwanted shocks and vibrations as a result of pyrotechnic detonations and breakage.

We have not consulted more data due to lack of time, since we have registered for the contest the day before.
Hackathon Journey
It is difficult to describe the experience since it has been all online and we have signed up at the last minute almost starting the Hackathon because the event was announced late for us. For my part (Jorge) I was not used to this user interface either. What has inspired us to choose this challenge is that one of the participants has experience doing DIY projects like drones.
The approach to the development of this project has been to think and design an eminently mechanical solution, although with the possibility of electric drive. For this, a simulation has been carried out with a version of 3D Studio MAX.
We have solved the complications and challenges as we have been able to carry out a preliminary design and look for information on the internet about calculating the resistance of materials.
We appreciate NASA for providing a meeting point for many students to develop and share their ideas.
