Overview
Kojiro is a humanoid robot with a musculoskeletal system that mimics how the human body works to generate motion. Developed at the University of Tokyo's JSK lab, the robot features artificial muscles and tendons, a flexible spine with cable-driven actuation, and 56 degrees of freedom. The goal is to build a robot that is light and agile, capable of moving much as people do.
