Stanford University researchers are working with NASA to design a spiked space apparatus capable of maneuvering efficiently across asteroid and moon surfaces, on which low gravity and rough terrain would bog down a regular rover.

Scientists nicknamed the robots "hedgehogs" due to their round, spiky appearance. Those working on the project hope to eventually land the 'hogs on Phobos, a Martian moon.
