Also when it is said that the prinscess is kept in the by maschines powered by BLOOD and FEAR

Now why would the robots run on blood and fear

Well if we take a guess that the robots used to be human even before the start of the episode and that in some way they failed to or refused against retrieving gwen for some hypothetical reson and that they were meant to be replaced by robots however in a hypothetical that olivia's mother was put in to gwen

(gwen being very maternal, oli having a portret of her family above her bed that portrays her dad, her mom that has blond hair(like oli does in the present) with oli herself having dark hair like her father, so in the present she oli dyes her hair blond so it reminds her of her mom which most probably died, specifically to something related to the blue goop most probably blue lung or some factory disaster after which they put her into a robot that oli had fir herself, which would also explain why this gwen is so much more human. It also explains why she has a humanoid intestines)

Most probably Oli wanted to put those two people into the robots because she was attached to them.

And fear because if they were to fail or rebel again they would have to relive pain or recieve abuse because as we see the sir Arthur robot has a scar on it's face
