Hangzhou Yushu Technology Co., Ltd., also known as Unitree Robotics, is a company that creates robots. It is located in Hangzhou, China. The company was started by Wang Xingxing in May 2016. At first, Unitree made robots with four legs for people to buy. In 2024, the company began making human-like robots. The newest model of these robots costs $16,000.
History
In 2013, Wang Xingxing created four-legged robots while studying for his master's degree at Shanghai University. On August 26, 2016, Wang Xingxing started a company called "Hangzhou Unitree Technology Co., Ltd." in a small office that was 50 square meters in size, located in Binjiang District, Hangzhou. His first four-legged robot, named XDog, was built in 2016 as part of his master's thesis. The robot became very popular online, drawing interest from buyers and investors. After working at a company called DJI in China, Wang decided to leave his job and start Unitree.
In 2021, Unitree released a robot called Unitree Go1, which is similar to a robot named Spot made by Boston Dynamics. This robot has twelve motors; each motor can produce a maximum torque of 23.7 N⋅m (17.5 lbf⋅ft) and can spin at speeds up to 30 rad/s (about 280 rpm). According to an article in The Wall Street Journal, the Unitree robot can move across different surfaces, such as sand, rocks, and soil.
In April 2024, Unitree shared a video showing a humanoid robot named H1. In August 2024, Unitree released an improved version of H1 called G1, which is now being produced for sale at a price of US$16,000. The robot is designed for users to use in robotics research and can optionally share data with a network, allowing the robot to learn new automated tasks.
In January 2025, Unitree displayed its advanced robotics technology at the Consumer Electronics Show (CES) in Las Vegas. The event featured their consumer-grade four-legged robot Go2, its wheeled-leg version Go2-W, the industrial-grade wheeled-leg robot B2-W, and the general-purpose humanoid robots H1 and G1. This event showed Unitree's effort to grow its business in international markets.
In April 2025, the South China Morning Post reported that Unitree was considering an initial public offering (IPO) in Hong Kong. In July 2025, the company began preparing for an IPO with CITIC Securities. In March 2026, Unitree submitted an application to list on the Shanghai Stock Exchange.

Controversies
In August 2022, Unitree said it was not true that their Go1 robot was being used by the Russian Armed Forces.
In September 2023, the United States Marine Corps used an M72 LAW anti-tank rocket launcher attached to a Go1 robotic dog during training exercises at the Marine Corps Air Ground Combat Center Twentynine Palms in California.
In May 2024, The Guardian reported that the Unitree Go2 robot was seen in China's joint military exercises with Cambodia, carrying an automatic rifle on its back. This information came from footage shown by China Central Television. Unitree stated in the same month that it does not sell its products to the People's Liberation Army.
In May 2025, the US House Select Committee on China asked the Federal Communications Commission, the US Department of Commerce, and the US Department of Defense to investigate Unitree about possible links to the People's Liberation Army and its military–civil fusion programs.
In April 2025, security researchers claimed that Unitree had included hidden access points in their products that allowed the company to remotely control Unitree devices and other devices on the same network. Unitree denied this, saying the issue was a weakness that had been fixed.
In September 2025, security researchers reported that the Unitree G1 Humanoid robot collects and shares sensor data without telling the user, and that its security flaws could be used in cyber attacks. At the same time, the researchers found a vulnerability that could let someone nearby take full control of Unitree's Go2 and B2 quadrupeds and G1 and H1 humanoids using Bluetooth. Infected robots could then spread the vulnerability to nearby robots. As of September 29, 2025, Unitree has not responded to these reports.
