Boston Dynamics, the advanced robotics company known for displaying its machines engaged in mildly terrifying dance routines, is back at it again for the holidays. This year, the company released a brief video clip that shows its four-legged "Spot" robot tiptoeing across an icy, winter-themed warehouse floor with Christmas music softly playing in the background. The scene then cuts to its new, more slender Atlas humanoid robot draped in a Santa Claus outfit, white beard and all. A low-humming mechanical sound can be heard moments before Atlas suddenly hurls itself into the sky for a backflip. It sticks the landing perfectly.
