This beautiful piece weighing 6 kilograms runs on gasoline and can be in the air for an hour at an altitude of 3 kilometers and move at a speed of 90 km / h, while transmitting images from conventional and infrared cameras. Passed tests in the FAA and is adopted by the Miami police. The police promise to use it only when conducting counter-terrorist operations, but of course, many against. Remember this?

Seem to be? Yeah. A technology has been used for several years, and there are similar devices weighing only 3 kg and capable of flying up to 4 hours. They promise in the near future devices the size of a small bird and protect their borders.

And I would like to have such a thing (only small and electrically driven) for personal use. A bunch of applications - fly instead of me to a lecture or concert, so that I watch / listen from another place or later in the recording; can be released from the car - see where you can go around traffic jams or something else, in general, google maps in real time, but a million applications can be found.
If you dream at all, then in the cities everywhere there were parking places for recharging such pieces, and using a special protocol, the devices communicate with each other, avoiding collisions, and with any base stations that will allow them, for example, to automatically find their way in buildings (you specify to room 453, the device gives a request to the server of the building, it gives a route).
