Microsoft Rolls Out Robot Security Guards

An anonymous reader writes: Microsoft is testing a group of five robot security guards. They contain a sophisticated sensor suite that includes 360-degree HD video, thermal imaging, night vision, LIDAR, and audio recorders. They can also detect various chemicals and radiation signatures, and do some rudimentary behavioral analysis on people they see. (And they look a bit like Daleks.) The robots are unarmed, so we don't have to worry about a revolt just yet, but they can sound an alarm and call for human officers. They weigh about 300 lbs each, can last roughly a day on a battery charge, and know to head to the charging station when they're low on power.
