Unitree Robotics

In 2013, Wang Xingxing developed quadrupeds during his postgraduate studies at Shanghai University. On 26 August 2016, Wang Xingxing registered and established "Hangzhou Unitree Technology Co., Ltd." in a 50-square-metre (540 sq ft) office in Binjiang District, Hangzhou. His first quadruped device, XDog, was developed in 2016 for his master's thesis. The robotic dog became an Internet sensation which attracted buyers and investors. After Wang started to work at the Chinese company DJI, he decided to resign and start his own company, Unitree.

In 2021, Unitree released Unitree Go1, a quadruped robot similar to Boston Dynamics' Spot. It is fitted with 12 motors; each can generate a maximum torque of 23.7 N⋅m (17.5 lbf⋅ft) and can spin at speeds of up to 30 rad/s (about 280 rpm). According to an article by The Wall Street Journal, the Unitree robotic dog can navigate in different surfaces including sand, rocks, and soil.

In April 2024, Unitree released a video showcasing the humanoid robot H1. In August 2024, Unitree released the G1, an upgraded version of the H1, for mass production at a price point of about US$16,000. The G1 utilizes a configuration of 23 to 43 permanent magnet synchronous motor (PMSM) rotary joint actuators capable of peak knee torque ratings between 90 N.m and 120 N.m depending on the variant. The machine was designed for users to participate in robotics research and optionally share data with a network allowing the robot to learn new automated services. The G1 has gained fame as the basis of robot's interacting with the public that are puppeted by remote operators, examples being the Polish “Edward Warchocki” and the American “Rizzbot”.

In January 2025, Unitree showcased its advanced robotics technology at the Consumer Electronics Show in Las Vegas. The exhibition featured their consumer-grade quadrupedal robot Go2, its wheeled-leg variant Go2-W, the industrial-grade wheeled-leg robot B2-W, and the general-purpose humanoid robots H1 and G1. This participation marked Unitree's commitment to expanding its presence in international markets.

In April 2025, the South China Morning Post reported that Unitree was exploring the possibility of holding an initial public offering (IPO) in Hong Kong. The company had previously received investment from venture capital funds such as HongShan, Matrix Partners, and Shunwei Capital. In July 2025, the company began its IPO tutoring process with CITIC Securities. In March 2026, it filed for an initial IPO to list on the Shanghai Stock Exchange. In August 2026, Unitree Robotics completed its IPO and began trading on the Shanghai Stock Exchange, with its shares surging nearly 500% on their first day of trading. Other major shareholders include the National Social Security Fund, CNPC Kunlun, DeepSeek, China Southern Power Grid, and Tianyi Capital, as well as affiliates of Tencent, Meituan, Alibaba and Ant Group.

In August 2026, the company demonstrated a humanoid robot dubbed "Superman" that could run up to 12.66 metres per second (28.3 miles per hour), faster than Jamaican sprinter Usain Bolt, and jump 2 m (6+1⁄2 feet) from a standing position.

Use by the military

In August 2022, Unitree denied allegations about reports of their Go1 robot being used by the Russian Armed Forces.

In September 2023, the United States Marine Corps used an M72 LAW anti-tank rocket launcher fixed to a Go1 robotic dog during tactical training at the Marine Corps Air Ground Combat Center Twentynine Palms in California.

In May 2024, The Guardian reported the Unitree Go2 robot has been used during China's joint military drills with Cambodia, with an automatic rifle on its back. According to the newspaper, this was based on footage broadcast by China Central Television. Unitree, in the same month, stated they do not sell their products to the People's Liberation Army.

In May 2025, the US House Select Committee on China requested the Federal Communications Commission, the US Department of Commerce, and the US Department of Defense to investigate Unitree regarding its alleged connections with the People's Liberation Army and its military-civil fusion programs. In June 2026, the US Department of Defense added Unitree to a list of Chinese military-linked companies.

Security

In April 2025, security researchers alleged Unitree had put backdoors into their products that allowed the company to remotely access Unitree devices and even other devices on the same network. Unitree responded by denying that it was an intentional backdoor, and claiming it was a vulnerability that has since been fixed.

In September 2025, security researchers revealed the Unitree G1 Humanoid robot collects data and reports multi-modal sensor data without notifying the operator and could be used in an offensive cyber attack given weaknesses in its security. Also in September 2025, the same security researchers published a wormable vulnerability that allows an attacker in close proximity to gain full control of Unitree's Go2 and B2 quadrupeds and G1 and H1 humanoids (over BLE). Infected robots would in turn be able to compromise other robots nearby. As of 29 September 2025, Unitree has declined to comment.
