I’m not sure if their an art project or practical tool but these autonomous biomorphic Robot Jellyfish are interesting. From National Geographic:
Propelled by flexible, electrically driven tentacles, robotic jellyfish swim at the Hannover Fair.
Using a type of “swarm intelligence,” the Festo company’s so-called AquaJellies set their own courses and can come together or avoid each other as needed. The robots “talk” via light pulses underwater and via radio at the surface.
On Technium Kevin Kelly writes:
One one level, these autonomous robotic jelly fish illuminated the mechanism by which real jellyfish swim. … The parallels in their motions — clearly visible in the video — feel so organic that we immediately assign them life-like adjectives.
I think we are primed to find lifelikeness in machines. E.O. Wilson calls it our biophilia — our intense attraction to living things. As we design machines to approach the complexity of organisms and mimic their behavior (as these do), we will be very quick to include them in our love.
