Robot Built for Climbing Alien Cliffs
An agile robot is being groomed to scale volcanic cliffs on Mars, climb down sheer crater walls on the moon, and traverse the craggy faces of asteroids.

This strange looking device is called a Lemur IIb robot. It is designed to one day climbing the steep terrain, such as the Valles Marineris, to retrieve rock samples. This will help scientists unlock clues about how the Mariner Valley was formed. It will also give scientists a better understanding of the different layers of sediment that might be on Mars.

Here is the homepage of Lemur bot where you can read more about the technology behind him. It is going to be challenging for scientists to figure out how to send data back that the Lemur bot collects, because Lemur does not seem large enough, nor should be, to be able to house the batteries and antenna large enough to send a signal back to earth. Then again this might be one of the several different types of robots that the folks at JPL want to use to do their sample return mission.
