Clone Robotics' Protoclone has a skeleton and 1,000 artificial muscles
Clone Robotics' Protoclone is built on a human-shaped synthetic skeleton driven by 1,000 Myofiber artificial muscles and integrated sensors, with over 200 degrees of freedom. Instead of motors at the joints, the muscles pull on bone attachment points the way biological muscles do. Protoclone V1 was shown running on pneumatic actuation, with the company saying future iterations would switch to hydraulics; Clone's more recent androids use a hydraulic vascular system to drive the muscles. The latest hardware shown is Torso 3, revealed in March 2026.
