Kenshiro Robot Imitates Real Muscles and Bones

Kenshiro is a human-like musculoskeletal robot in development at the University of Tokyo. They have added more muscles and more motors to their Kojiro robot from 2010, making Kenshiro’s underlying structure the closest to a human’s form so far.


Kenshiro mimics the body of a 12-year-old male, standing at 158 centimeters tall and weighing 50 kilograms. Its body mirrors almost all the major muscles in a human, with 160 pulley-like “muscles”—50 in the legs, 76 in the trunk, 12 in the shoulder, and 22 in the neck. It has the most muscles of any other bio-inspired humanoid out there.
