## Summary

During a live demonstration at the "2026 World Physical AI Conference and Unitree Partner Ecosystem Conference," Unitree Technology's H2-X humanoid robot, just released on October 21, lost balance and fell sideways while attempting a side somersault landing, and one mechanical lower leg detached from its connection point. The robot is 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. Official promotional videos have shown it kicking in car doors, lifting vehicles, and performing a somersault after jumping down from a platform about 4 meters high. As of the time of reporting, Unitree Technology had not commented on the incident.
