In 2019, China began using robots to keep control of its roads. The Handan Public Security Bureau now employs three styles of robot that help their existing officers maintain order. The three robots are similar in design, but they each carry out very different functions.
One type, the road patrol robot, seeks out and documents any criminal behavior on the roads. Its designers have even given it a uniform and hat to look more like a human officer. Another, the accident warning robot, informs nearby drivers that the police are dealing with an incident. The third type is the advice traffic robot, which helps direct drivers at vehicle management stations, whilst also keeping an eye out for security risks.
People in China are no strangers to robot police officers. In 2016, authorities started to use a security robot in Shenzhen Airport, and in 2017 an E-Patrol Sheriff was introduced in Henan.
