I’m very skeptical of the video. It looks like toy stuff, lacking the heft and power of a drone sized to carry a payload that heavy. And then it cuts to a different view/zoom level when Fido-matic comes to life. Barely a step above Godzilla movies, IMO...
“I’m very skeptical of the video.”
You probably should be. Even the Boston Dynamics videos are all hype. Their actual “robot dogs” are not controlled by AI; all their motions need to be hard-coded and the robot is normally connected to a controlling computer by a whole bunch of cables. They just disconnect it for their short PR videos, but you can still see the metal gantry that the cables run along in most of the videos.
