Robot fetishism is the name popularly used to describe a fetishistic attraction to humanoid or non-humanoid robots or people dressed in robot costumes. A related fetish is agalmatophilia, which involves attraction to mannequins or statues. A common fantasy related to these fetishes involves transformation into a robot, mannequin, or statue.
It is sometimes referred to by the initials ASFR, from the alt.sex.fetish.robotsnewsgroup.
The gynoid in Fritz Lang's film Metropolis can be viewed as an early example of the robot as fetish object. Frank Zappa's classic concept album Joe's Garage dealt with robot fetishism as a sort of perversion where the protagonist, "Joe", sinks into a life of sexual confusion and meaningless experimentation. In Star Trek: The Next Generation, the android, Data, was the object of sexual desire more than once up to acutal sex and he was extensively programmed with numerous sexual techniques.
Although Capek's robots were organic artificial humans, the word robot is nearly always used to refer to mechanical humans.
In the general sense of automaton, the biggest robot in the world is said to be the Maeslantkering, a storm surge barrier in the Nieuwe Waterweg waterway near Hoek van Holland, Netherlands, which automatically closes when needed.
Robots are being used today to do the tasks that are either too dirty, dangerous, or dull for humans.
Sexual fetishism, first described as such by Sigmund Freud though the concept and certainly the activity is quite ancient, is a form of paraphilia where the object of affection is a specific inanimate object or part of a person's body.
Although Freud's theory on fetishes may seem peculiar and was based on anecdotal evidence rather than empirical, he had discovered a critical aspect of human sexuality: the relationship between human orgasms and conditioning.
Some clothing materials are fetishized by a small number of people, perhaps on the basis that the material forms a "second skin" that acts as a fetishistic surrogate for the wearer's own skin.
