We just found a new friend. Kojiro, a humanoid being built by the University of Tokyo's JSK Robotics Laboratory, has a detailed musculoskeletal system built to mimic the human body. It works on a system of artificial bones, muscles and tendons to create a robot that is theoretically more light and agile than your regular bot, and which moves in a more organic fashion to our untrained eyes. The bot has motors which pull cables that simulate the method which muscles and tendons interact, and has about 100 tendon-muscle structures, giving it 60 degrees of freedom -- more than an average rotary joint bot like Asimo (34 degrees, last time we checked). The robot shaves weight
