What's amazing about this vehicle is that the living quarters being carried around by this lunar robot will weigh 15 tons. What's great about this concept is that the same technology could be used to construct a base on Mars in advance of human explorers reaching the planet:
Giant robots could carry lunar bases on their backs
"NASA engineers are testing out a giant, six-legged robot that could pick up and move a future Moon base thousands of kilometres across the lunar surface, allowing astronauts to explore much more than just the area around their landing site. In a 2005 report about its exploration plans, NASA said it wanted to set up a base at a fixed location on the Moon after initially returning humans there in 2020.
But a gargantuan robotic vehicle called ATHLETE (All-Terrain Hex-Legged Extra-Terrestrial Explorer) could change that. Measuring about 7.5 metres wide, with legs more than 6 metres long, the robot could act essentially like a turtle, carrying the astronauts' living quarters around on its back. It was designed by engineers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, US, who are now testing two small-scale prototypes of the robot."
