There's now no way to hide from the robot apocalypse.
Robotics design firm Boston Dynamics has shown off its advanced technology in a chilling new video.
The clip, posted to YouTube, shows off a new feature on its dog-like robot, SpotMini.
One yellow dogbot approaches the door - only to be stumped by the closed door.
Fortunately, it has a friend. Another yellow SpotMini marches up and uses a claw mount on its head to reach out and open the handle. It then holds the door open for its friend to enter.
The video has drawn comparisons with an episode from hit sci-fi TV show Black Mirror, which features robotic dogs hunting down humanity.
