A humanoid robot performing a choreographed dance routine for a crowd at a shopping mall in Shaanxi province, China lurched toward spectators mid-spin and struck a young boy in the face with its arm. The robot’s perception system failed to detect the child’s presence and the unit continued its routine after impact. No protective barriers separated the audience from the robot during the performance. The incident, which went viral online, prompted safety experts to call for mandatory collision-avoidance systems on robots operating near the public.
