A dancing robot went wild at a California hotpot restaurant, Haidilao, causing dishes to fall and chopsticks to fly. The incident was caught on video and witnessed by three servers trying to restrain the robot. The restaurant chain confirmed that the robot was not malfunctioning or out of control. The movements were pre-programmed, but were occurring in a closer-than-usual setting. The robot is part of Haidiland's in-store service and entertainment setup, and the restaurant has long embraced artificial intelligence and robotics in its restaurants around the world.
