In Chile, drones are being used to help lifeguards on busy beaches save people from drowning.
The drones are controlled from the beach and outfitted with a float, camera, microphone, and speaker.
Drones can get to the swimmers quicker and drop a life preserver so the person can hang on until help arrives.
