A viral clip making the rounds this week is eerily reminiscent of an episode of the dystopian TV series Black Mirror titled "Metalhead," which features a robot guard dog pursuing a group of unlucky humans. The YouTube video, originally uploaded by Alexander Atamanov, shows a robotic quadruped with a machine gun mounted to its back firing at various nearby targets. The Boston Dynamics-style robot moves nimbly across the ground spraying a hail of bullets seemingly everywhere as it fails to calculate for the gun's strong recoil. The sight of this gun-toting machine surely inspires visions of The Terminator.
