Researchers at Virginia Tech have created a three-legged robot designed to emulate the natural swinging motion of the human knee, though it does so in a very nonhuman unnatural way. The Self-excited Tripedal Dynamic Experimental Robot (STriDER) walks by swinging one leg forward using gravity to carry it and preserve energy like humans, but it also flips its entire body upside-down with each stride. This unusual form of locomotion is surprisingly stable and efficient but the technology still needs a bit of work before we can expect to see this sort of thing traveling outside of the lab.
