Chinese robot company Unitree Robotics held an online investor meeting on Friday for its initial public offering (IPO) on the Shanghai Stock Exchange's STAR Market, with Unitree founder Wang Xingxing saying the firm will continue to advance key software and hardware technologies and explore a broader range of product forms and models.
The company is set to become China's first publicly listed humanoid robot maker, representing an important milestone not only for Unitree itself but also for China's booming robotics industry. Greater access to capital will further accelerate technological innovation and promote the high-quality development of the robotics industry, an expert noted.
Speaking at the online investor meeting, Unitree founder Wang Xingxing said the firm will continue to advance key software and hardware technologies, including embodied AI foundation models, scenario-based data collection and analysis, reinforcement learning, embodied robot models, in-house development of core components, and high-performance actuators.
Wang revealed that the company is also actively exploring a broader range of product forms and models, including humanoid robots, quadruped robots and mecha robots, with the aim of enabling robots to take on physically demanding and high-risk tasks, freeing up human creativity and advancing robotics technology for the benefit of society.
Talking about the potential for the robotics industry, Wang said multiple factors are driving market demand, including an aging population, rising labor costs and growing demand for higher productivity and a better quality of life.
Against this backdrop, high-performance general-purpose robots capable of assisting humans with a wide range of tasks are emerging as an important solution to labor shortages and productivity bottlenecks, pointing to vast market potential, Wang noted.
Since its establishment, Unitree has focused on the research, development, production and sales of high-performance general-purpose humanoid robots, quadruped robots, robotic components and embodied AI models.
Reviewing the company's performance, Wang said his company has recorded steady growth in recent years. In 2025, while its net profit excluding non-recurring items grew rapidly, the company also ranked first globally in humanoid robot shipments.
Ahead of the roadshow, Unitree unveiled the pricing of its IPO and the results of its strategic placement. The company announced on Thursday that its IPO on the STAR Market was priced at 150.80 yuan per share.
Unitree will issue about 40.45 million shares, accounting for 10 percent of its total shares after the offering. The IPO is expected to raise about 6.1 billion yuan, exceeding its previously planned fundraising target of 4.2 billion yuan.
Unitree has attracted significant market attention and is expected to become the first humanoid robot company listed on China's A-share market, Liu Dingding, a veteran industry analyst, told the Global Times on Friday, noting that the company's upcoming listing would mark an important milestone not only for the company but also for China's robotics industry, which is accelerating its commercialization and market-oriented development.
More importantly, for Unitree, tapping the capital market will provide stronger support for sustained R&D investment and capacity expansion, Liu said, adding that "greater access to capital could significantly shorten R&D and market validation cycles that might otherwise take three to five years, further enhancing the global competitiveness of China's robotics industry."
The company is well aware that its current achievements are only a starting point, said Wang at Friday's roadshow. The embodied AI industry is still at an early stage of development, similar to the early days of home appliances and personal computers, and further progress will require joint efforts across the industry, he said.
Founded in 2016, Unitree mainly produces humanoid robots and quadruped robots. According to its prospectus, the company shipped more than 5,500 humanoid robots in 2025, ranking first globally. From 2023 to 2025, Unitree sold more than 33,000 quadruped robots, cementing its leading position in the global quadruped robot market.
The rapid growth of China's robotics industry is underpinned by the country's complete industrial chain and production capabilities. China is now home to more than 140 humanoid robot manufacturers, with annual shipments reaching 14,400 units, accounting for 84.7 percent of the global total, CCTV News reported. In other words, roughly eight out of every 10 humanoid robots shipped worldwide come from China.
。大桥合龙后，设计时速350公里的广汕高铁建设将进入全线轨道铺设阶段。广汕高铁是广东省重点工程之一，起自广州新塘站，终至汕尾站。广汕高铁增江特大桥成功合龙，即将进入全线铺轨阶段。王建国摄由广铁集团广州工程建设指挥部建设管理、中国铁路广州工程局承建的增江特大桥为双塔双索面混凝土斜拉桥，为广汕高铁关键控制性工程。大桥位于广州市增城区石滩镇境内，全长2569.480米，桥梁主跨 260米跨越增江水道，主塔采用高100米H型桥塔。主桥在全世界高速铁路斜拉桥建设中首次采用混凝土梁节段预制胶拼法施工，利用混凝土梁体自重大的特点，克服一般斜拉桥受空气流动性影响产生涡振现象，同时采用大型剪力键，提高梁体拼接缝的抗剪力性能。节段梁拼装通过纵向粗预应力钢棒与粘结胶有效结合，将各节段梁串联成整体而成桥，加大了梁体的刚性，降低了斜拉桥柔性变化特点，提高了高速铁路行车舒适性和安全性。
