Unitree’s newly unveiled H2-X humanoid robot stumbled and lost part of a leg during a kung fu demonstration at the 2026 World Physical AI Conference & Unitree Partner Ecosystem Summit in Hangzhou, East China’s Zhejiang Province, footage circulating online shows.
The incident occurred on Thursday, a day after Unitree unveiled the H2-X on Wednesday. Video of the event shows the robot failing a side flip and shedding part of a leg during the performance.
Unitree H2-X demo and reactions
A day earlier, Unitree released a video showing the H2-X kicking in a car door, lifting the front of a vehicle and performing a flip after jumping from a platform approximately 4 meters high. The company says the H2-X is intended for security and emergency rescue applications. Unitree had not publicly commented as of press time and did not respond to a request for comment on Sunday.
The mishap drew mixed reactions on the Chinese social media platform Sina Weibo. Some users said such errors should be reduced even if the robot is not yet mass-produced, while others described glitches as a natural part of technological progress. A netizen calling themselves “Nana” wrote that the incident should not be taken as a wholesale rejection of robotics but highlighted room for improvement in motion algorithms and mechanical design. Another user, “Qiuyezhiyin,” urged improvements to structural rigidity. A separate net user argued that engineering must account not only for speed but also for material strength and design redundancy, and that extensive testing is necessary to ensure product safety and quality.
On-site displays at the conference featured other Unitree technologies, including AI cluster demonstrations and intelligent guidance functions for humanoid robots such as the G1 and H2-X.
Context: founder remarks and market response
At the same conference, Unitree Robotics founder and CEO Wang Xingxing spoke about the challenges of moving robots from demonstrations into real-world applications. Wang said embodied intelligence could reach its ‘ChatGPT moment’ as early as next year, predicting that “Physical artificial intelligence is showing signs of a breakthrough, most likely within the next one to two years, or two to three years,” according to CCTV News.
Following the event, Unitree’s shares rose 20 percent on October 23, closing at 624 yuan ($93.55) per share and bringing the company’s market capitalization to approximately 252.38 billion yuan, according to the Beijing Daily.
