A gynoid (or fembot) is a humanoid robot that is gendered feminine.
Gynoids appear widely in science fiction film and art.
The first gynoid in film, the maschinenmensch ("machine-human"), also called "Parody", "Futura", "Robotrix", or the "Maria impersonator", in Fritz Lang's Metropolis is also an example: a femininely shaped robot is given skin so that she is not known to be a robot and successfully impersonates the imprisoned Maria and works convincingly as an exotic dancer.
They fought in two multi-part episodes of the series: "Kill Oscar" and "Fembots in Las Vegas", and despite the feminine prefix, there were also male versions, including some designed to impersonate particular individuals for the purpose of infiltration.
Not only did the servo motor and platform have to be ‘interiorized’ (naizosuru), but the body [of the fembot] needed to be slender, both extremely difficult undertakings.
Researchers have noted the connection between the design of feminine robots and roboticists' assumptions about gendered appearance and labor.
While not truly artificially intelligent, the fembots still had extremely sophisticated programming that allowed them to pass for human in most situations.
