The amazing sweating robot

At 5½ feet tall, its face fixed between a grin and a grimace, the humanoid robot Kengoro is something of a synthetic Arnold Schwarzenegger. That is not to say the machine, created by the University of Tokyo's JSK laboratory, is a recursive time-traveling assassin. Rather, Kengoro is a sweaty beefcake among metal bipeds. The average two-legged machine does not have Kengoro's stamina. For a svelte robot, Kengoro is strong, powered by 108 motors.
