## Summary

During a live kung fu demonstration at the "2026 World Physical AI Conference and Unitree Partner Ecosystem Conference," the Unitree H2-X humanoid robot lost balance on landing from a side flip and fell sideways, with one mechanical lower leg detaching from its joint. The robot was just released on October 21, officially named "H2-X Kung Fu Legend Guardian," and is positioned for security and emergency rescue scenarios with a maximum battery life of about 8 hours. Promotional videos show it kicking in car doors, lifting a car bare-handed, and performing a flip after jumping from a platform about 4 meters high. As of now, Unitree has not commented on the incident.
