Researchers said on Monday they had designed the first robotic leg with “artificial muscles”—oil-filled bags allowing machines to move more like humans—that can jump nimbly across a range of surfaces.

The small, disembodied robot leg was shown hopping over grass, sand and rocks in a video released alongside a new study in Nature Communications
