The incident happened on April 23 during the opening ceremony of a sports competition at Xi’an Eurasia University in Shaanxi Province, where a humanoid robot approached the student and suddenly wrapped its arms around her as she was leading a group of students dancing.

Staff responsible for operating the robot quickly stepped in and pulled the machine away, according to Chinese news site Shangyou News.

The robot’s unexpected behavior quickly triggered discussion on Chinese social media. Some netizens wondered whether the robot had developed "independent awareness," while others questioned whether the move was controlled by an operator or had been arranged in advance as part of the performance.

A university staff member denied that the action was pre-programmed, saying "based on what we understood at the time, the robot made a mistake," and attributed the incident to an AI program malfunction, according to Global Times.

The robot supplier later said the issue was caused by signal interference at the venue. According to the company, multiple drones were operating at the same time during the performance, disrupting the robot’s signal and causing abnormal behavior.

Gao Huan, deputy director of the Intelligent and Cognitive Laboratory at Chongqing Normal University, said the incident was likely caused by abnormalities in motion control, execution errors, or the lack of an on-site backup safety system.

Robots used in performances typically operate based on pre-programmed movement scripts. If positioning errors, posture recognition deviations, sequence failures, or unexpected movement by human performers occur, unintended collisions between robots and people can happen, he explained.

Gao added that in open scenarios such as human-robot collaborative dance, exhibition interactions, and campus performances, robots should not be treated merely as ordinary stage props, but as intelligent devices with inherent mechanical motion risks.

He said organizers, operators, and robot suppliers should conduct advance risk assessments before human-robot performances, including movement testing, on-site rehearsals, safety distance setup, emergency stop mechanisms, staff supervision, and contingency plans for unexpected situations.
