Robots are starting to replace human security guards in Singapore

It's no RoboCop, but this autonomous patrol bot is going to be seen more and more often around Singapore. Ademco, a local security services company, recently launched a rent-a-robot service, in response to fewer people signing up to work as security guards. The 1.6m-tall robots are less like China's egg-shaped robot police, but more like a submarine, with five cameras on its long neck, two front cameras, and four wheels. The robot can also record licence plates, as well as a 360-degree view of surrounding activities from up to 10 meters (32 feet) away. It'll also send alerts to a 24-hour manned command center if it detects abnormalities like fire or loud sounds.
