We have seen plenty of researchers working on perfecting lunar rovers. TU Delft’s Lunar Zebro aims to be the first Dutch and European rover to walk on the moon. It takes about the same size as an A4 sheet of paper and uses c-shape legs to move.
This 6-legged rover can climb over much taller obstacles than wheeled robots. The above video gives you a better idea what Lunar Zebro is all about.
