UBTECH Robotics Corp Ltd (Chinese: 优必选科技; stock code: 9880.HK) is a Chinese robotics company headquartered in the Nanshan District of Shenzhen, Guangdong, China. Founded in March 2012 by Zhou Jian (also known as James Zhou), the company specializes in humanoid robots, educational robots, and commercial service robots. [1] UBTECH became the first humanoid robot company to go public when it listed on the Hong Kong Stock Exchange (HKEX) on December 29, 2023. [2][3]
UBTECH develops full-stack humanoid robotics technology, from proprietary servo actuators and motion control systems to computer vision, natural language processing, and SLAM navigation. [1] The company has sold over 760,000 robots across more than 50 countries and holds over 2,790 robotics and artificial intelligence-related patents as of mid-2025. [1] Its product lineup spans consumer education robots, commercial service robots, and industrial-grade humanoid robots deployed in automotive manufacturing facilities operated by companies such as BYD, Audi, Geely, and Foxconn. [6]
Zhou Jian founded UBTECH in March 2012 with RMB 10 million in registered capital. [1] Originally from Shanghai, Zhou developed a passion for robotics during childhood, partly inspired by the Transformers animated series. Before founding UBTECH, Zhou had been working on robotics since 2008, initially focusing on developing servo motors as foundational components for robotic joints. These early efforts in servo technology laid the groundwork for the company's later humanoid robot systems. [1]
UBTECH's first major product was the Alpha 1S, a small programmable humanoid robot released in 2016 that targeted the consumer and education markets. The Alpha series showcased the company's proprietary servo motor technology and helped establish its brand in the educational robotics segment.
In July 2016, UBTECH secured US$100 million in financing from CDH Capital and iFlytek, achieving a post-investment valuation of US$1 billion and becoming a unicorn company.
In 2016, UBTECH launched the Jimu Robot line, an interactive robotic building block system aimed at children aged 8 and up. The Jimu series combined real servo motors with snap-together building blocks, allowing users to build, program, and share their robot creations through a companion app. The product line expanded to include themed kits such as BuilderBots, Astrobot, and the Competitive Series.
In January 2017, UBTECH introduced Cruzr, a cloud-based intelligent commercial service robot designed for retail stores, hotels, hospitals, airports, and corporate offices.

Later in 2017, UBTECH partnered with Disney to release the Star Wars First Order Stormtrooper Robot, a consumer product that combined facial recognition, augmented reality, and voice commands. The Stormtrooper robot was sold through Amazon, Best Buy, and Apple retail stores.
At CES 2018 in January, UBTECH unveiled Walker, its first full-sized bipedal humanoid robot targeted at consumers. [18] Standing approximately four feet tall, the original Walker demonstrated true bipedal motion, including the ability to walk, kick a soccer ball, and navigate stairs. UBTECH described it as a "complete home butler" designed for household and office assistance. [18]
In May 2018, UBTECH raised approximately US$820 million in a Series C funding round led by Tencent Holdings, valuing the company at around US$5 billion. [5] This was one of the largest funding rounds for a robotics company at the time and cemented UBTECH's position as a leading player in the Chinese robotics industry. [5]
In the years following its Series C raise, UBTECH increasingly shifted its focus toward industrial and commercial applications of humanoid robots. The company unveiled Walker X in 2021, a significantly upgraded humanoid with 41 high-torque servo joints, 7-degree-of-freedom arms, and 6-degree-of-freedom force-controlled hands capable of performing tasks such as opening bottles, pouring liquids, and handing objects to people. [15] Walker X also featured improved vision-based navigation and hand-eye coordination. [15]
In 2023, UBTECH introduced the Walker S, a humanoid robot designed specifically for industrial scenarios. Standing 1.7 meters tall and equipped with 41 servo joints with force feedback alongside multiple visual, audio, and distance sensors, Walker S was designed for deployment on automotive assembly lines. That year, UBTECH began collaborating with NIO, placing Walker S robots on the production line at NIO's advanced vehicle manufacturing center in Hefei, where the robots performed tasks including door lock inspection, headlight cover inspection, seat belt verification, and car badge application.
Two Walker X units were also exported to NEOM, the Saudi Arabian megaproject, and the commercial service robot Cruzr participated at Riyadh Season, Saudi Arabia's largest cultural festival, providing guidance services to visitors.
On December 29, 2023, UBTECH listed on the main board of the Hong Kong Stock Exchange under stock code 9880.HK, becoming the first humanoid robot company to complete an initial public offering. [2][3] The company sold 11.3 million new shares at HK$90 per share (the lower end of its HK$86-HK$116 target range), raising approximately HK$1 billion (roughly US$130 million). [2] The IPO gave UBTECH a market capitalization of approximately HK$37.6 billion (about US$4.8 billion). [4] In a notable moment, UBTECH's Walker S humanoid robot struck the listing gong alongside founder Zhou Jian, marking the first time a humanoid robot rang the opening bell at the HKEX in its 132-year history. [3]
In 2024, UBTECH launched the Walker S1, a next-generation industrial humanoid robot. [7] Standing 1.72 meters tall and weighing 76 kilograms, Walker S1 features 41 degrees of freedom with high-torque, high-speed electric actuators. [7] The robot integrates large language model-based general task planning and semantic VSLAM navigation. It can walk at speeds up to 1.5 m/s while carrying a 15-kilogram payload and is capable of performing quality inspections with accuracy rates exceeding 99 percent. [7] Walker S1 was deployed for pilot trials at the Audi-FAW production base in Changchun for air-conditioning leak detection and completed the world's first multi-robot, multi-task, multi-scenario collaborative training at a 5G smart factory operated by Zeekr (Geely's premium electric vehicle brand). [6]
In July 2025, UBTECH introduced the Walker S2, described as the world's first industrial humanoid robot capable of autonomously swapping its own batteries within three minutes. [8] Standing 1.76 meters tall with 52 degrees of freedom, the Walker S2 integrates Co-Agent, UBTECH's proprietary intelligent agent system that provides closed-loop operational capabilities including intention understanding, task planning, tool usage, and autonomous anomaly detection. [8] The S2 can lift a 15-kilogram payload and achieve a waist rotation angle of plus or minus 162 degrees. [8]
By November 2025, UBTECH began mass production and delivery of the first batch of several hundred Walker S2 units, making it one of the first large-scale deliveries of full-sized industrial humanoid robots globally. [9] The company reported more than 800 million yuan (approximately US$112 million) in Walker series orders since early 2025 and announced plans to scale production capacity to 5,000 units annually by 2026 and 10,000 units by 2027. [9]
In September 2025, UBTECH secured a credit line of up to US$1 billion from Infini Capital, a Hong Kong and Abu Dhabi-based investment firm. [10][11] The two companies announced plans to establish a joint venture to build a "superfactory," a research and development center, and regional headquarters in the Middle East. [11] Infini Capital planned to take a 5 percent stake in UBTECH and leverage its previous investments in AI and robotics supply chains to support development of more powerful and cost-effective humanoid robots. [19]
Zhou Jian (周剑), known internationally as James Zhou, serves as Chairman, CEO, and Executive Director of UBTECH Robotics. [1] Born in Shanghai around 1976, Zhou holds a Bachelor of Arts in International Business/Trade/Commerce from Tianjin Foreign Studies University and a Master of Business Administration from Concordia University-Wisconsin in the United States.
Zhou's interest in robotics began in childhood, and he started working on robotic systems in 2008, concentrating initially on the development of servo motors for robotic joints. After founding UBTECH in 2012 with a 78 percent shareholding, he built the company from a small servo motor operation into one of China's largest robotics firms. [1]
Following the December 2023 IPO, Zhou became a billionaire. His direct 24.8 percent stake in the company was valued at approximately US$1.2 billion based on the initial market capitalization. [4]
