Two of my favorite things, beautifully combined!

Festo has developed a graceful robot inspired by a creature of the sea. In fact, they have developed two versions, both based on the common jellyfish: the AquaJelly and the AirJelly. According to Festo, the AquaJelly is “an artificial autonomous jellyfish with an electric drive and an intelligent, adaptive mechanical system.” As for the AirJelly, this remote controlled device can glide through the air using a helium-filled ballonet, a central electric drive and an intelligent, adaptive mechanical system.

This video reminded me of other robot fish making recent news:

The movement is rather well done, though if the creators were aiming for realism the fish could have been a bit less “bedazzled.” Perhaps I just balk at anything too closely resembling this.
