To power through more pushups, this robot breaks a sweat

Like humans, robots that are working hard generate a lot of heat, a byproduct that adds stress to their systems and limits the amount of time they can be active before they need to recharge. One of the things that makes humans such good distance runners is our ability to sweat, a liquid discharge that helps to cool our bodies as it evaporates. Researchers at the University of Tokyo's JSK lab decided to borrow from that behavior to try and improve robotic performance, building a metal frame that
