What happened

A Unitree H1 humanoid robot being tested at a facility in China suddenly went berserk, wildly flailing its arms and legs and knocking over equipment including a computer. Two engineers had to scramble to avoid being hit before one regained control by pulling the robot's support stand back. Preliminary reports attributed the malfunction to a coding/algorithm error in the robot's balance-control software. Captured on CCTV, the video went viral.
