Animal-Like Robots Could Explore Planets

If the visionaries of today have their way tomorrow, NASA planners in the future could unleash an odd-looking menagerie of robots to explore planets and space in ways that humans never will. Researchers envision things like 3-foot- (1-meter-) long dragonfly-like robots to buzz high above Mars, mechanical eels and seahorses to swim deep beneath the ice on Jupiter’s moon Europa or “self-transforming” plastic explorers that can morph themselves into different shapes.
