The Diodon drone is a hexacopter which is able to inflate itself into a tiny carry case when it lands on water. Even if you accidentally crash it into the waters, it will not sink; instead it will float and folds away. With a central waterproof box, the motors and foldable devices sit on the six inflatable tubes. The drone can be collected and return to its original state in just a minute or two when attached to an air pump.
The entire frame is made up of airframe buoyant enough to float on water. This allows the drone to be able to fly in heavy rain or sea condition. If the one or two of the arms of the drone deflates mid-air, it would cause a major damage to the drone.
Manufactured by France’s Airvada, they plan to see three different yet similar version of the Diodon drone from SP20, which measures 700 x 700 x 100 mm (27.5 x 27.5 x 3.9 inches). The SP20 can carry camera size of a GoPro and has a flight time of 20 minutes. The MP40 measures 1,200 x 1,200 x 150 mm (47.2 x 47.2 x 5.9 inches), able to carry compact camera with gimbal, flying up to 30 minutes. The other model, HP150, measures 1,500 x 1,500 x 200 mm (59 x 59 x 7.9 inches), capable of carrying a stabilized 1.5kg (3.3 lb) camera for up to 35 minutes.
The prices of the different models have to been released yet. You can check out their official website for updates, and also the demo video below (in French):
