writes "Most human-like robots don't even attempt biological accuracy, because replicating every muscle in the body isn't necessary for a functional humanoid. Even biomimetic robots based on animals don't attempt to replicate every anatomical detail of the animals they imitate, because that would needlessly complicate things. That said, there is much to be learned from how muscle groups move and interact with the skeleton, which is why a team at Tokyo University's JSK Lab has developed what could be considered the world's most anatomically correct robot to date.
The robot, Kenshiro, was presented at the annual Humanoids conference this month. It models the average 12 year-old Japanese boy, standing 158 cm (5 feet, 2 inches) tall and weighing 50 kg (110 pounds). According to Yuto Nakanishi, the project leader, keeping the robot's weight down was a difficult balancing act. Nonetheless, the team managed to create muscles which reproduce nearly the same joint torque as real muscles, and that are roughly five times more powerful than Kojiro's."Link to Original Source
