A Freaky Humanoid Robot That Sweats as It Does Push-Ups

Continuing their quest to make me feel even worse about being a lazy human, robots can now do sit-ups and push-ups and something called a back extension, which I had to look up because that’s how lazy I am. Your typical humanoid robot moves thanks to actuators—a fancy name for a motor combined with a gearbox—in its joints. Kengoro’s 116 actuators instead pull on wires that mimic the contraction of human muscles. That’s all thanks to those "muscles," in contrast to just a handful of motors powering the joints of a more traditional humanoid.
