If she's hiding it, she's not hiding it well enough. Because I already thought she was a robot when she didn't stand up. Then she Slendermans in front of Weiss.

A non-robot theory is that Penny grew up with little to no human contact, so she's worse than even Jaune and Ruby in terms of social skills. One possible evidence is when she explodes into a ball of happiness after Ruby became 'friends' with her.

(Also, please tell me 'wired' was intentional...)

Most "Trying to not act like a robot" characters (usually female) are not obvious to the in-universe characters. From a meta perspective, however, she's basically trying too hard that it warps right back into 'I AM A ROBOT'.
