None of these are robots, they are all cyborg's or androids. Why make a thread about sexy robots if they are all gonna look like beautiful women?
Technically speaking, there isn't a single android here, as an android is specifically a robot with a male appearance.
A robot with a female appearance is a gynoid.
It is worth noting, however, that the word "android" is an expression that is acceptable in common parlance to refer to both gender appearances.
