The ‘bot is 158 centimeters tall and weighs 50 kilograms, which makes it about the size of a 12-year-old Japanese boy, complete with an aluminum bone-structure. It’s accurately human, too: the individual bones and muscles are placed where they would be in a real person, and its limbs are proportional to the weight of a human’s. This video only shows the individual limbs, but put Kenshiro back together and team it up with this robot dad we recently saw, and you’ve got a biologically accurate robo-family. IEEE Spectrum
