There is a new cop at a railway station in China’s central Henan province, and don't expect him to show any mercy to perpetrators as he is a robot, China News Agency reported, according to Sputnik news.

The patrol robot, on duty at Zhengzhou East Railway Station since February 17, can scan passengers' faces and respond to questions, ria.ru reports.

Painted in black and white, the robotic patrolman moves around on wheels. Using a number of sensors it monitors air quality, temperature, guards the station during the night and can even set off the fire emergency alarm.

Even though this is the first police robot to patrol a railway station in China, robotic security guards were earlier deployed at one of the country’s airports.
