“Everything stopped,” Oleg Kivokurtsev, Promobot’s co-founder, tells Digital Trends. “It’s not every day that people meet a robot, I guess. There was a small traffic jam and one person called the police.”

Fortunately (or unfortunately, depending on your perspective), Promobot’s quest for freedom was short-lived since, upon crossing the road, it promptly ran out of batteries. Its escape wasn’t exactly the stuff of prison break movies either, but the fault of an engineer who was putting the bot through its paces.
