Students at the Delft University of Technology (TU Delft) in the Netherlands are developing the world’s smallest and lightest moon rover, called Lunar Zebro.
Named after the Dutch phrase for “six-legged,” Lunar Zebro will indeed have six legs instead of wheels, allowing it to climb taller obstacles on the moon than its wheeled counterparts can overcome. The rover will be the size of a standard sheet of paper and weigh about 5.5 pounds (2.5 kilograms).
“The most unique feature of the Zebro is its locomotion, of course, which is done using C-shaped legs based on the RHex project from the University of Pennsylvania,” Simon J. Stenger, the project’s chief engineer, said in a video about the project. “This enables the rover to traverse difficult terrains without getting stuck.”
