Boston Dynamics has taught its fleet of SpotMini robot dogs a new trick: The robotics company posted a new video featuring ten of the mechanical canines hauling a cargo truck up a slightly inclined hill like a team of sled dogs. The video was shared to the company's popular YouTube page on Tuesday. In the above video, two lines of SpotMini's are tethered together and marched in unison to inch a semi-truck in neutral gear forward. As with pretty much every video Boston Dynamics publishes, it elicited a flurry of Black Mirror, Terminator, and robot overlord-themed references across social media. But Boston Dynamics promises that its famous SpotMinis are here to help humans, not to rule them.
