The AquaJelly (for water) and the AirJelly (a flying 'jellyfish') are made by the German company Festo.The AquaJelly communicates via short-range radio when near the surface of water, and by light while underneath.
“Each jellyfish decides autonomously which action to carry out on the basis of its current condition. This central electric drive, combined with an adaptive mechanical system and intelligent autonomous electronics, opens up possible new applications for self-controlling systems. If a large number of AquaJellies were equipped with communicative abilities, these could act like a shoal with the behaviour pattern of a more highly developed system. If one applies this principle to automation, then numerous autonomous or semi-autonomous intelligent systems might be able to work together.”
