MACAU — A woman on an evening walk in Macau was briefly hospitalized after she was startled by a humanoid robot and felt unwell, according to a police statement. The incident occurred earlier this month.

The police received a call for assistance for the woman after she noticed a robot behind her while using her mobile phone, according to a police statement. The woman did not suffer any injuries and there was no physical contact with the robot, but she required hospital treatment, according to a police statement. Video footage captured the woman saying "With so many other things to do, why bother me? Are you crazy?" and "You're making my heart race!"

The robot was operated by a Macanese man in his 50s who said he was conducting a test and intended to use it for promoting his business, according to the robot operator. The robot belonged to an education center that was conducting promotional activities in the area. Social media videos showed officers leading the robot away.

The woman was discharged from the hospital and did not press charges related to the incident, according to a police statement. Police said they did not seize the robot, according to a police statement. Mak Kin Choi accompanied the woman to the hospital and escorted her home early the next day, according to Mak Kin Choi.

Police reminded the robot operator to stay vigilant while operating the robot to avoid causing danger or alarm to passersby, according to a police statement. Similar promotional activities with robots have been carried out recently in other areas and received positive feedback, according to Mak Kin Choi.

The robot in the images resembled a humanoid model made by the Chinese startup Unitree. Fully automated humanoid robots remain uncommon, with most displays pre-programmed or remotely operated.
