We wrote about Festo’s Air_ray last year on OhGizmo. If you haven’t seen it, it’s totally cool, and Festo has taken the concept of sea creatures flying in air a step further with this beautiful robotic jelly. The bell of the AirJelly is filled with helium to provide lift, and lithium-ion batteries provide power to the tentacles which propel the jelly through the air:
Festo’s Aqua Jelly operates on generally the same principle, except underwater. And it’s autonomous and has LEDs! Soothing video of a few of them swimming around, after the jump.
