I think it's still the same "uncanny valley" phenomenon: because the body looks more like a human, we are more creeped when we discover how it moves its joints because we were expecting something more human. We wouldn't be creeped by a car/robot moving its wheels in weird directions, but we are with a humanoid robot moving its legs that way.

In particular, the sections of the demo video where it does something anatomically impossible for humans -- rotating legs in the hip joints, rotating its torso to switch front and back -- are absolutely uncanny valley stuff.

It looks like its possessed.

Something straight out of Exorcist.

The head at least needs to be changed and made to look more friendly, or at least not like an emotionless alien eyeing you up for paperclip conversion.

It's a bit odd to follow the human form factor (I get the logic - for a human-designed world), but then not at least also give it a human-looking head, or maybe better a dumb/cute looking head.

Wouldn't a more friendly looking face push us further into the uncanny valley and make it more creepy, not less?

I wouldn't have thought so, but it's hard to predict how people are going to viscerally react!

I wouldn't have anticipated people finding the rotation/double-jointedness creepy, but it does seem to be a fairly widespread reaction.
