Floats like a jellyfish, in air and in sea

AirJelly is a remote-controlled helium balloon that was shown off at the Hanover Messe last week. The video above demonstrates the radical way it moves around the air, what’s even more impressive is that the AirJelly uses nothing more powerful than a pair of lithium-ion-polymer batteries to make flight. Designed by German company Festo, it has a sub-aquatic partner, the AquaJelly (see below) that can move around underwater equally gracefully. The pair of prototypes are part of a new generation of autonomous vehicles, which include the AquaRay and its airborne sibling, the AirRay.
