Recently, eagle - eyed netizens have observed that humanoid robots have taken on the role of security guards at select Shenzhen Metro stations, setting off a flurry of public discussions. The images circulating online depict robots donning vests emblazoned with the words "Security Guard," standing steadfast at the security checkpoints.

According to a reply from Shenzhen Metro's customer service team, robot security guards have been in operation on Line 12 for more than six months. Their main function is to act as intelligent customer service representatives, tackling straightforward tasks. These robots are outfitted with advanced visual recognition technology. This enables them to inspect passengers' luggage, remind travelers about beverage restrictions during security checks, offer station navigation assistance, and even make heart - shaped hand gestures or strike poses for photos with passengers.

The metro authorities have clarified that the introduction of these robots has not resulted in any job cuts. Instead, their deployment is intended to boost operational efficiency and inject a touch of entertainment into the daily commute.
