OK, you've probably seen this video by now. I'm going to go out on a limb and say this looks fake as f**k to me. It just looks like mediocre CGI. I'm not seeing any compelling evidence that this thing exists as a complex machine in three-dimensional space with this alleged robot, and certainly not as it comes onscreen.
It's not even that it looks like someone in a suit, it just looks like the most talented kid in your local high school computer animation lab showing off to that girl he's sweet on.
