Tuopu Group

A Ningbo auto-parts giant transforming itself into a humanoid-robot actuator supplier.

Tuopu Group traces back to 1983, when founder Jianshu Wu started making auto parts in Ningbo; its predecessor, Ningbo Tuopu Brake Systems, was set up in 2004, and the company listed on the Shanghai Stock Exchange in 2015 (ticker 601689). Its core business covers damping systems, interior components, chassis, automotive electronics, and thermal management, and it is a major supplier to new-energy automakers including Tesla. It is applying its automotive supply-chain capability to enter humanoid robotics, starting with linear actuators — components that turn a motor's rotation into linear push-pull motion, commonly used in robot arms and legs — and expanding into rotary actuators, dexterous-hand motors, structural parts, and sensors, with a planned Ningbo robot-core-component base carrying roughly RMB 5 billion in total investment. The market widely views it as an actuator supplier for Tesla's Optimus, though the company has not confirmed this item by item. In December 2025 it announced plans for a Hong Kong listing, filing with the Hong Kong Stock Exchange in April 2026 to pursue a dual A+H listing.

ExampleA humanoid robot needs dozens of actuators per unit, and automotive-supply-chain vendors like Tuopu bring car-grade mass-production lines to bear on cutting the cost per unit.
