Could this four-legged robotic canine become a man's best friend or ultimate foe?
The Spot Mini quadruped robot , developed by Boston Dynamics, moves just like a dog.
And a new redesigned version has the added feature of an arm that can extend out if its head.
This robot is so dexterous that it can open doors on its own.
It put this arm to good use in the video when it expertly and smoothly opened the door and even held it open for its robot friend to pass through.
