Late last night Boston Dynamics dropped a new video of its robot dog, SpotMini, in action. It walks up some stairs (no big deal--it's done that before) and then through some corridors, periodically extending its camera-equipped arm to survey bits of a construction site. This is where--given the theatrics of pretty much every other Boston Dynamics video that's come before it--Spot should have done something righteous. Perhaps fighting a human to open a door. But no, just a nice fade to black.
