Scientists in Japan have developed robots that can sweat.
The scientists built two robots, named Kengoro and Kenshiro, that look a lot like humans, with skeletons and everything.
They used aluminum, steel and plastic as a frame -- and designed synthetic joints and ligaments to enable the robots to move. They have rib cages. They have flexible spines. And, they have an artificial central nervous system that monitors balance and stability.
They programed the things to actually work out, doing sit ups and pushups. To keep them from overheating during their workouts, the scientists also programmed the robots to sweat. (Daily Mail)
