Japanese scientists build world's sweatiest robot

As we exercise, our bodies can produce a lot of heat as our muscles convert chemical energy into mechanical energy. To keep moving effectively during such conditions, we produce sweat to cool ourselves down. As the water in our sweat evaporates, it takes excess heat with it, allowing us to keep moving without overheating. A team from the University of Tokyo has created a robot that can exercise and cool off in a similar way, inspired by human sweat. The new robot is named Kengoro.
