The race in industrial robotics is really a race in core components, and China is closing the gap fast. In 2026, localization of the three key parts — reducers, servo systems, and controllers — has accelerated across the supply chain.
Servo systems, the “muscles” of a robot, are the clearest success story. Industry data from gongkong.com show domestic servo motors and drives passed 40% localization in China this year, priced at 60–70% of imported units. Inovance Technology has overtaken Panasonic to become the country’s No.1 servo supplier — a shift few predicted five years ago, when Japanese brands led the market.
Reducers, the most expensive component and historically the biggest bottleneck, are also improving. Leader Harmonious Drive holds about 60% of the domestic harmonic reducer market in 2026, with service life up from 5,000 hours in early models to 8,000 hours, approaching Harmonic Drive’s 10,000-hour level. In RV reducers, where Nabtesco and Sumitomo still control roughly 80% globally, Chinese firms Shuanghuan Transmission and Qinchuan Machine Tool are gaining ground in automotive and battery applications.
System-level results are visible too. Unitree’s prospectus discloses over 80% self-developed core components and more than 90% localization of core technology for its robots, with motors, reducers, and controllers made in-house. The economics are clear: higher localization has helped compress costs while keeping margins healthy.
Policy is adding momentum. At an Oct. 20 press conference, Chinese officials confirmed next-generation intelligent manufacturing as the national priority and said MIIT is drafting policies to fuse AI with the whole manufacturing chain, widening the market for localized components.
The takeaway: Chinese industrial robots are being built not only cheaper but stronger and more self-reliant, from the joint to the system.
