Human v robot dog: Boston Dynamics takes on its door-opening SpotMini - video

Boston Dynamics' four-legged machine SpotMini has already proved that it can easily open a door and walk through unchallenged, but now the robotics firm is teaching its robo-canines to fight back.

This video shows SpotMini approaching the door as before, but this time it's joined by a human with an ice hockey stick. Unperturbed by his distractions, SpotMini continues to grab the handle and turn it.
