Robots are on the loose in Russia—or one was on Wednesday, causing mayhem and a traffic jam. Officials say a robot trained to move around on its own made an escape from a science lab in the city of Perm. The robot, or Promobot—created to market products to humans at events, per Quartz—went through a gate that a scientist had apparently left open, then traveled 164 feet before its battery died, leaving it frozen in the middle of a busy street, per the BBC. Forty minutes after its escape, it was wheeled back to the lab uninjured. (More Russia stories.)
