Unitree humanoid robot loses a leg during public demonstration
Unitree Robotics’ H2-X humanoid robot lost a lower leg after falling during a side flip at a conference in Hangzhou, China.
The robot had been unveiled the day before the demonstration and was performing martial arts-style movements on a cushioned mat.
Unitree markets the H2-X for security patrols and emergency rescue, as well as other protective work.
A forceful landing and problems with balance or the leg joint could cause such a failure, but the specific cause has not been confirmed.
The incident highlights the challenge of making robots perform dynamic movements reliably outside controlled settings.
Unitree has not announced an investigation result or improvement plan, and observers are awaiting the company’s response.
