Robot fetishism (also ASFR, robosexuality, and robophilia) is a fetishistic attraction to humanoid robots; also to people acting like robots or people dressed in robot costumes. A less common fantasy involves transformation into a robot. In these ways, it is similar to agalmatophilia, which involves attraction to or transformation into statues or mannequins.
ASFR
By its enthusiasts, robot fetishism is more commonly referred to by the initials "ASFR". This initialism stems from the now-defunct Usenet newsgroup alt.sex.fetish.robots. Many devotees of this fetish refer to themselves as technosexual, or as "ASFRians".

The first of these is simply a desire to have a ready-made android partner. This partner can be desired for sex, companionship, or any combination of the two. The main distinguishing feature of this fantasy is that the android is a completely artificial construct, often manufactured solely to fulfil the wishes of its owner. This type of fantasy or situation is referred to as "built".
The second type of fantasy prevalent within ASFR is referred to as "transformation". This involves a human who has been either willingly or unwillingly turned into an android. That person can be either oneself or one's partner, or both. It is usually the process of transformation (through whatever means it is achieved) that is the focus of this fantasy.
The aspects of this fetish that are most appreciated by members of the ASFR community are greatly varied. For some, things like robotic appearance, motion, or sound are important for arousal. television shows, novels, short stories, illustrations, manipulated photographs, songs and even television commercials. Such works are sought after by technosexuals since economically viable androids are not yet available. Realistic sex dolls such as the RealDoll may provide a way to explore this fetish with existing technology. Recent developments in robotics and artificial intelligence, such as those seen in the Actroid or EveR-1 may lead to the production of more advanced synthetic partners.
