From fast food cooks to doormen at restaurants and hotels, robots are slowly entering the workforce in nearly every industry. Most recently, the world welcomed its first operational robot policeman.

“Robocop”, the newest member of the Dubai police force, made the first public appearance on Sunday at the Fourth Gulf Information Security Expo and Conference, where it greeted guests. At about 70 inches tall and weighing nearly 220 pounds, Robocop seeks to engage with residents and tourists. Featuring an “emotion detector (探测器)”, the robot can recognize a person’s gestures and body language from about 5 feet away.

Robocop’s skills don’t stop there—the emotionally intelligent bot can detect if a person is happy, sad and even angry by studying his or her facial expression. And just like your human friends would do, if Robocop sees you’re unhappy, it will try to lift your spirits. More importantly, when it comes to fighting crime, the robot uses the Internet, artificial intelligence and other smart technologies to spot offenders using facial recognition. Its navigation (导航) skills grant it the ability to map out areas and travel on its own. Equipped with a built-in tablet, Robocop can communicate with people, speak six languages, respond to public inquiries, shake hands and even make military salutes.

“With the aim to assist people on the streets,” said Brigadier-General Khalid Nasser A1 Razzouqi, director-general of smart services at Dubai Police, “the Robocop is the latest smart addition to the force and has been designed to help us fight crime recently, keep the city safe and improve happiness levels.”
