The All-Terrain Hex-Legged Extra-Terrestrial Explorer (ATHLETE) rover is a next-generation robotic lunar exploration vehicle.
ATHLETE is designed to load and transport heavy loads across the rough lunar surface. Each rover can carry half a ton and multiple rovers can work together to transport heavier loads.
ATHLETE can roll and walk across the lunar surface and can even use a grappling hook to rappel down steep slopes.
There are some amazing videos of ATHLETE in action at its JPL homepage.
