It's a "You Send It" file so, you know, get it while it's hot.
Apparently, however, this has already been shot down as a fake. Although, studios can lie and aren't shy from it.
It's not a dancing robot by any means but notice the detail during transformation. The way the car panels seem to shake and move. The way the robot tries to remain balanced as it gets its footing. Little things like that. But yeah, it's fake, right?
