In a somewhat unusual incident in Macau, China, a humanoid robot model Unitree G1 was 'detained' by the local police for causing fear to an elderly woman. The incident took place around 9 PM local time on Rua Sul do Patane. The woman, while checking her phone, became startled when she sensed something behind her, which turned out to be the robot. The proximity of the robot to her appeared to be the cause of her fright, prompting an emotional reaction.

The woman was reported to have exclaimed, 'You are making my heart race!' reflecting her shock and frustration at encountering the robot unexpectedly. Fortunately, the police confirmed that there was no physical interaction between the robot and the woman; however, she did seek medical assistance due to the significant emotional discomfort she experienced from the ordeal. Such incidents raise questions about the impact of humanoid robots on public safety and emotional wellbeing, particularly for vulnerable populations.

Following the occurrence, the police intervened, ensuring the woman's safety by escorting the robot away from the area. This incident underlines the importance of considering the public's perception and reaction to advanced robotics, especially in urban settings where people may not be accustomed to such technology. It also opens up discussions on regulations that might be necessary to prevent similar occurrences in the future.
