Dubbed Cyro, the newly unveiled robotic jellyfish is a scaled-up version of another mechanical swimmer, this one the size of a human hand, called RoboJelly that was developed by the same team of researchers at Virginia Tech College of Engineering.
At 5-foot-7 (1.7 meters) and weighing 170 pounds (77 kilograms), Cyro is the jelly equivalent of an average human guy. [Read more on the man-size jellyfish bot]
"You can throw it, and it won't collapse. Most mechanical parts are rigid and fragile at small scale, but the parts in Meshworms are all fibrous and flexible," said mechanical engineering researcher Sangbae Kim in a statement from MIT. "The muscles are soft, and the body is soft … we're starting to show some body-morphing capability," added Kim, who with colleagues described the robot in 2012 in the journal Transactions on Mechatronics.

In a feat detailed Feb. 5, 2013, in the journal Bioinspiration and Biomimetics, the moth was able to "drive" the robot by walking on a rotating polystyrene ball onboard, like a trackball controlling a computer cursor. The insect drove the robot inside a wind tunnel, which simulated the flow of air the moth would feel if it were flying. The moth drove upwind to track the pheromone.

The space robot is part of the Phoenix program, a project by the Defense Advanced Research Projects Agency (DARPA) to recycle space junk back into valuable satellite parts, or even completely new spacecraft. DARPA scientists began the project in July 2013 and are working toward launching the first demonstration mission in two years or so.

Getting the mechanical cheetah up to this speed required researchers to improve the computer instructions that control its legs and back, whose flexible design are key to its speed, IEEE Spectrum reported.
