"Kojiro is an advanced musculoskeletal humanoid robot under development at the University of Tokyo's JSK Robotics Laboratory. Kojiro's creators designed its body to mimic the way our skeleton, muscles, and tendons work to generate motion. The goal is to build robots that are light and agile, capable of moving around and interacting with the physical world in the same way our flesh bodies do."
