I discovered these hypnotic robotic jellyfish on a German website, Festo. I can't read German. Is it art? Technology? I love fusions.
Google Translator, that cryptic oracle, says:
"Project name is an artificial autonomous jellyfish in the water, which has self-governing system as a distinct swarm behavior. Project name consists of a translucent hemisphere and eight tentacles that serve the propulsion. In the center of AquaJelly is a watertight, pressure laser sintered body. This includes inside a central, electric drive, two lithium-ion polymer batteries, the charge control and the servo motors for the swashplate."
