In the past few years the US armed forces and other US Government agencies have been spending a lot of their funds on funding and allotting their projects to Universities and technical institutes across the United States. Most recent projects are robotic projects that mimic animals and can be used for potential surveillance and assistance to the armed forces both on and off the battlefield.
Here is another awesome potential spying/surveillance robot being developed by the Graduate students of Virginia Tech College of Engineering. This time its a Jelly Fish and its called 'Cryo'.

Cryo is basically a prototype robot that looks very much like a giant jelly fish. Its 5.7 feet wide (1.7 meters) and weighs in at 170 lbs (77kg) and its designed to be neutrally buoyant. The inspiration for the design is the 'Lion's mane jellyfish' also termed the 'Cyanea capillata' by biologist, that's were the name 'Cryo' comes from.
