In Google translated German:

Air is the element of AirJelly. The remote does not swim through water jellyfish AirJelly as AquaJelly, but literally glides through its central electric drive and an intelligent adaptive mechanism by the sea air. For AirJelly consists of a helium-filled ballonet.

As the only energy source used AirJelly two lithium-ion polymer batteries to which the central electric drive is connected. This transfers the force to a bevel gear and then successively to eight spur gears, which move about cranking the eight tentacles of the jellyfish. Each tentacle is as a structure with Fin Ray Effect® trained. The drive of a balloon by means of peristaltic motion is currently not in the history of aviation. AirJelly is the first indoor flying object with peristaltic drive. The jellyfish moves through this new drive concept based on the reaction principle of their propulsion, gently through the air.

There’s also an AirRay – a mechanical manta ray
