Asahi Power Service, a Japanese company, designed an umbrella drones. It flies over the user's head to protect him from rain. Although it is called Free Parasol, the drona is not free. The device will cost when it reaches the market next year, $ 273.
Free Parasol uses artificial intelligence to keep track of the user accurately. It will have to hope that everything works impeccably. That's because such a dron will weigh, in the final version, 1 kg. Now it weighs 5 kg, and the propellers are not protected.
Free Parasol will be able to fly, with the fully charged battery, for 60 minutes. However, not everyone can use it. In Japan, dwarfs are banned in densely populated areas.
