You have got a strange way about ya
Germany-based Festo company developed two robotic jellyfish, AquaJelly and AirJelly.
AquaJelly is an artificial autonomous jellyfish with an electric drive and an intelligent, adaptive mechanical system. AquaJelly consists of a translucent hemisphere and eight tentacles used for propulsion.
Rather than swimming through water like the AquaJelly, AirJelly glides through the air with the aid of its central electric drive and an intelligent, adaptive mechanical system. The remote-controlled AirJelly is kept in the air by its helium-filled ballonet. The AirJelly’s only energy source are two lithium-ion-polymer batteries, to which the central electric drive is attached.
