Tuopu Group

Tuopu Group is a leading Chinese automotive lightweight-chassis and suspension-component manufacturer that has developed its own rotary actuator technology and is described as a Tesla rotary-actuator supplier for humanoid robots. Tesla accounts for a significant share of Tuopu's revenue.

Tuopu's core competency in lightweight structural engineering and precision manufacturing for automotive chassis systems has given it the tooling, materials expertise, and quality processes needed to develop high-performance rotary actuators for robotic joints. The company leveraged its deep Tesla automotive supply relationship to position itself in Tesla's Optimus humanoid program as a rotary-actuator supplier, a role that has drawn considerable attention from investors tracking the humanoid supply chain. Rotary actuators are among the most mechanically demanding components in a humanoid robot, requiring tight tolerances, high torque-to-weight ratios, and long operational life — engineering challenges that align with Tuopu's automotive heritage. The company's dual role as an automotive-volume manufacturer and an emerging robotics component supplier gives it cost structure advantages as humanoid production eventually scales.
