The ability to sweat is allowing a humanoid robot to work harder.

Scientists at the University of Tokyo have developed a cooling system to reduce the heat pressures created by the 100 motors that power Kengoro. A team from the the university released their research on the humanoid at a robotics conference in South Korea this week.

Lead author Toyotaka Kozuki told the IEEE Spectrum science website: “Usually the frame of a robot is only used to support forces. Our concept was adding more functions to the frame, using it to transfer water, release heat, and at the same time support forces.”
