Engineers from Imperial College London have created a drone that can dive and emerge from the water. The device is called AquaMav. When you enter the water the machine folds its wings like a sea bird, and to exit the water jumps like a flying fish. Once in the air, he again spread his wings.
The drone weighs 200 grams. Under water he speeds up to 50 km/h. the Researchers plan to use such devices to fees for water samples. Taking samples, the drone uses carbon dioxide to rise from under the water. At the moment the range AquaMav is about 5 km away.
