Jellyfish robots

Via Ectoplasmosis: "Festo, a robotics company who has previously designed robots based upon the mechanics of sea creatures, has released video of their newest creations. Based on jellyfish the AquaJelly and Air Jelly are sea and air based, respectively.

"The AquaJelly in particular is especially interesting. The idea is that these autonomous robots can communicate with each other and with aquatic charging stations using LEDs, allowing them to replenish their batteries and work in groups, making it much easier for them to wipe out our naval forces once they achieve self awareness."
