The concept of a "robot sex doll" in science fiction can be traced back to the early 20th century, but the first notable instance often cited is in the 1927 silent film Metropolis by Fritz Lang, based on the novel by Thea von Harbou. In Metropolis, a scientist creates a humanoid robot, Maria, which is designed to seduce and manipulate people. While this robot isn&39;t explicitly a "sex doll," it introduces the idea of an artificial being used for human pleasure and manipulation.
In terms of literature, Philip K. Dick&39;s Do Androids Dream of Electric Sheep? (1968), which inspired Blade Runner, features androids (called "replicants") that are indistinguishable from humans and can engage in intimate relationships, touching on the themes of humanandroid interactions, including sexuality.
These works paved the way for later explorations of robots designed for intimate and sexual purposes in scifi literature and media.
