9. Dubai

Robot Dubai cop

The Dubai Police Force has an unusual worker on its police force: a robot. Its face is human-like in appearance -- with two cameras for eyes. It wears a police hat on its head and has two arms. A touchscreen on its chest allows pedestrians to report crime in the area or pay for traffic tickets.

The police force hopes 25% of its officers will be Robocops by 2030. The robot doesn't carry a gun or make arrests.

Other cities also use security robots, but they're not as humanlike in appearance as Dubai's robot.

Knightscope, a Silicon Valley company, sells its own security robot that resembles an oversized R2D2. The robots record video of their surroundings and have thermal imaging abilities to sense potential intruders. One of the robots accidentally fell into a pool in Washington, D.C. earlier this summer.
