Its name is Robojelly - and the mass of carbon nanotubes and smart materials can swim under its own power, with a 'pulsing' movement that looks just like the real thing.More worryingly for robophobes, the robot jellyfish also never runs out of batteries.
Thankfully, it's here to help mankind - at least in theory. The blob-like machine is designed to help with underwater rescues.
Robojelly is able to mimic the natural movements of a jellyfish when placed in a water tank - and is powered by chemical reactions taking place on its surface.
In real jellyfish, circles of muscles pulse to move the creature through the water.
In Robojelly, carbon nanotubes wrapped around hi-tech 'shape memory' alloys (metals which 'pop' back to their original shape), achieve the same effect. Read More
