Don't believe him, just watch. Spot the robo-dog has another trick up his sleeve in a new video where he can be seen twerking to Bruno Mars' dance-worthy hit'Uptown Funk.' Boston Dynamics, the secretive firm behind the four-legged droid, released the video on Tuesday. If you thought humans were safe from the impending robot takeover on the dance floor, you might want to think again. In the minute-long clip, Spot can be seen stepping and moving almost perfectly in time with the music. And in a testament to Spot's precise motor control, the robot performs his own version of the popular Running Man dance.
