Every year in the Caspian Sea in northern Iran, numerous people drown. In fact on my mother’s side of the family a distant cousin was lost to that sea. The father of three drowned while swimming with his children. There was no lifeguard to save him. This is a tragedy which has happened to numerous families in Iran who vacation there.
Now imagine a drone, which can act as a lifeguard. One which can deliver a swimming ring to a person who is drowning in the sea, day or night. A drone which can be tracked by satellite, and charged with solar power energy.
Such a drone has been designed by an Iranian company called RTS Idea.
Here is a very interesting video about their invention. Their next project is an oil spill cleanup robot.
