Okay, so HUME is just a pair of legs right now, but what a pair of legs! Each knee features elastic actuators that let it perform deep knee bends, meaning it can climb over rocks and other tall obstacles. The company behind it, Meka Robotics, also has developed a pair of advanced arms with seven degrees of freedom and hands with a strong, responsive grip, plus pressure-sensitive “skin” that can detect even the slightest touch.
Pros: Not deterred by rubble in disaster areas.
Cons: Different components have never been combined, which makes for a very incomplete rescue bot.
