The robot police officer patrols one of Chinese railway stations

The machine took up its duties last week. It works at the Zhengzhou Railway Station in Henan analyzing the level of air pollution, temperature and humidity each day. But there are other responsibilities. For example, it also helps police in search of criminals.

For this purpose the robot has face recognition sensors. It is also programmed to inform fire departments in case of detecting fire areas. And, finally, the machine is able to cooperate with people, answer simple questions and provide helpful information.

Currently, the robot only works in departure lounge. According to Liu Shubin, director of the Zhengzhou Railway Station, the machine will be tested for a week. They are planning to use the robot mainly at night.
