An automated security robot in Washington D.C. took a dip yesterday, helping secure a solid 5 extra years before human security guards are replaced.

The robot, a Knightscope K5, rolled into a fountain at an office building it was guarding. It seems to have taken a tumble down some stairs, landing on its side and half-submerged in the fountain.

As many tweeters noted, the robot could have been fed up with the daily slog, deciding to end it all rather than spend another day wandering around the office plaza. The K5, which stands about 5 feet tall and weighs 300 pounds, monitors for unauthorized movement, records security footage and can sound an alarm in normal operation.

This isn’t the first time a K5 has showed some un-robot-like fallibility. Earlier this year, a similar model was tipped over by a drunk man in Silicon Valley. If this is the beginning of the robot revolution, the goals of these mechanical usurpers may be a long sway off.
