Does that feel unnerving to you? I haven't noticed anything abnormal about it. It doesn't trigger anything like the Uncanny Valley for me. A robot is a robot.
Absolutely. Those legs look like something out of an 80s horror movie, with the jerky movements of a stop-motion special effect. Honestly, I don't think I've ever seen anything deeper into the uncanny valley than that unholy abomination. The first time I saw it, I started imagining it walking towards me and accidentally ripping off one of my limbs or something. I am however still impressed by the technology.
Interesting. Are you sure it's the Uncanny Valley and not your preconception of an Evil Robot Out There to Murder You?
Who knows, really, but I don't walk around with fantasies of murderous robots, so I'm siding with the Uncanny Valley theory.
