Jiangsu Runtai Robot Technology Co., Ltd. - 江苏润泰机器人科技有限公司

Jiangsu Runtai Robot Technology Co., Ltd. is a robotics-components joint venture announced in 2025 between Jiangsu Rongtai Industry Co., Ltd. (Shanghai Stock Exchange: 605133), a publicly listed automotive aluminum die-casting and precision machining manufacturer headquartered in Yangzhou, Jiangsu, and Jiangsu Runfu Power Technology Co., Ltd., a company reported to hold patents in planetary roller screw design and based in Changzhou, Jiangsu. Under the joint-venture arrangement disclosed in Rongtai's investor communications, Rongtai holds a 45 percent equity stake and Runfu holds the remaining 55 percent, with the new entity capitalized at RMB 65 million in registered capital.

The joint venture was formed specifically to research, develop, and manufacture planetary roller screws and ball screws, precision linear-motion components that convert rotary motor output into linear force and displacement. According to Rongtai's own disclosures and subsequent industry press coverage, the venture's products are targeted at two end markets: actuation components for humanoid robot joints and limbs, and chassis systems for the automotive industry. Rongtai has publicly described the venture as opening a "second growth curve" alongside its existing automotive die-casting business, reflecting a broader trend of Chinese automotive-parts suppliers moving into humanoid-robot actuation components as that market scales. Related reporting also indicates the two partners are separately setting up a further joint venture focused on manufacturing the specialized equipment used to produce screws, underscoring an intent to build in-house manufacturing capability for this product line rather than outsourcing production.

As a newly formed joint venture, Jiangsu Runtai Robot Technology Co., Ltd. does not yet appear to maintain an independent, verifiable corporate website with published product literature; a candidate domain associated with the company name was registered only days before its appearance as a WRC 2026 exhibitor and could not be accessed to confirm ownership, so it has not been used as a source. Its business activity is instead documented through Rongtai's investor disclosures, financial-media coverage of the joint-venture announcement, and its listing as an exhibitor at the World Robot Conference 2026. Rongtai itself, founded in 2000 and headquartered in Yangzhou, Jiangsu, is an established automotive-industry supplier specializing in aluminum high-pressure die-casting, precision machining, and tooling development, and its corporate website is used here as the reference site for the joint venture, consistent with the venture's status as a majority-owned affiliate without its own confirmed web presence.

Because the venture is at an early operational stage, verifiable details such as its exact incorporation date, factory address, headcount, and specific product model numbers are not yet available through public, non-fabricated sources. Its documented relevance to the robotics supply chain rests on its explicit mandate, as disclosed by its publicly listed shareholder, to supply planetary roller screws and ball screws as core linear-actuation components for humanoid robots.
