I just saw this over at Supertouch and my jaw just dropped.

The robotic entity shown in the video above is the Festo AirJelly, a jellyfish-like robot that flies through the air. It was recently unveiled at the 2008 Hannover Messe in Germany.

According to the automatically translated page (thanks to Google), I can gather that the AirJelly is constructed partially with a helium-filled “ballonett” and is powered by two lithium-ion polymer batteries by which the central electric motor is connected (I’m assuming this motor moves the tentacles).

Here’s another video of the AirJelly flying about.

Festo is also the same group that showed off a similar “lighter-than-air” object called the Air_ray at Hannover Messe the year before. Check out the video of the Air_ray below.
