Moona hackathon 23.11.18, PubG team.
Our proposed system includes smart life belt which is dropped from a drone as soon as a drowning incident occurs. The life belt has a small gas tank which inflates it as soon as it hits the water, that way it is minimally influenced by the wind while being dropped.
In our implementation we used a 3D printed android module which is attached to the life belt. An Android phone gives the life belt a command to release the drone and after the module's free falling time inflation begins.
Video of the module in action can be seen in this YouTube video:
