A high tech security robot on patrol near a Georgetown office and retail complex in Washington D.C. drowned Monday after it tried to get in a bit of summer fun by taking a dip in a mall fountain. Photos of the robot toppled over and floating on its side in a fountain flooded Twitter after the incident.

The Knightscope K5 robot is typically used to monitor malls, office buildings, sporting arenas and other crowded areas. It’s equipped with 360-degree video streaming, forensic capabilities, autonomous presence and more, according to the Knightscope website.

Knightscope itself tweeted a joke about the incident.

The company was just getting in on the fun other Twitter users were having with the story.

One Twitter user even tweeted a photo of himself with the robot, taken a few days prior to Monday’s incident. He joked that the robot had seemed “happy” and “healthy” then.

Some saw the accidental drowning as a win for humans, who are at risk of losing their jobs to robots, as Elon Musk has warned previously.

Other users had suggestions about how to prevent this from happening in the future.

The responses the photos of the drowned bot brought on were mostly lighthearted. Many Twitter users made connections between the robot called Marvin in the book and film, The Hitchhiker's Guide to the Galaxy. Other users responded to the tweets of the incident with references to the show Doctor Who, and of course R2-D2 from Star Wars.

It’s currently unclear why the robot took the plunge and the incident is under investigation. Knightscope is sending a new robot this week, as their agreement with Washington Harbour states, at no extra cost, Stacy Dean Stephens, VP President Marketing & Sales at Knightscope told International Business Times. The robot, that stands at about five feet tall and weighs about 300 lbs, is equipped with several sensors to prevent it from running into any walls, water hazards or other areas of obstruction.

The size of the robot made it a bit difficult to retrieve from the water even though it wasn’t very deep. The photos of human security and maintenance workers trying to lift it up the steps into the fountain show what a difficult time they were having.

Knightscope called Monday's incident "isolated," so hopefully the next robot assigned to Harbour won't face the same fate.
