The K5 robots don’t come with any weapons onboard—thankfully—but they use a suite of alarms, sirens, and cameras to monitor and patrol the grounds of Microsoft’s campus. If one spots trouble, it’ll either sound an alarm or dispatch a human security guard to its location.

Dubbed the K5, Microsoft’s Silicon Valley campus was being policed last week by five of these roughly human-sized 300-pound (136 kg) robots, each equipped with enough cameras, sensors, artificial intelligence, and alarms that they can replace most human security patrols. Fortunately, despite looking like uncomfortably like a Dalek from the Doctor Who universe, the K5 is not (yet) equipped with a ray gun or any other method for harming or detaining humans.

Positive opinion
The K5 costs only $6.25 an hour and $36,000 a year. It can work over 24-hour period on a single charge.[20] Also, the K5 can effectively help prevent crimes in neighborhoods where there are not enough police forces.[21]
