It's not the fact that this four-legged robot can open a door, it's more about how he does it that makes it so cool.

Boston Dynamics' SpotMini is a nimble robot that handles objects, climbs stairs, and will operate in offices, homes and outdoors.

In the above video, you'll see one SpotMini walk up to a door and then realizes he can't open the door so he waits for his robot buddy to walk over and open it for him. He not only opens it but he also holds the door open for the other robot to walk through. So freakin' cool!
