Reiko is a pleasure bot, designed to go out and collect sexual experiences for her corporate masters to sell as virtual reality recordings, in the cyber-porn movie I.K.U. She goes to sex raves and transforms from android to human form. Or she hangs out in a glowing pink web, spangled with dildos. Some of the coolest robots in science fiction are designed only for carnal pleasure. We have a roundup, with sexy but work-safe images and one clip, after the jump.

Malice@Doll. (2000) Maybe the only philosophical tentacle porn anime movie ever. All the humans are dead, just like in that Conchords song, and the humanoid robots still go about their tasks. Malice@Doll is a sex robot, who wanders the streets looking in vain for human customers. One day, she follows a vision of a girl who seems to be human, and winds up getting captured by a tentacle monster, which penetrates her. A lot. And then she becomes human. She finds that her kiss can turn other robots organic too, but eventually discovers that some of the results are grotesque and horrifying. Sadly, it's not a very sexy movie, but Malice is sorta cute. Here's a still:Cherry 2000 (1987). She's the ultimate sex droid — as long as you don't get her wet. Businessman Sam Treadwell ignores this important lesson and short-circuits his sexbot. So he has to hire E. Johnson (Melanie Griffith), a tracker, to get a replacement memory chip for her. As he travels with E., Treadwell learns (bah) that flesh-and-blood lovers are better than robo-babes.

I.K.U. (2000) Japan's most famous cyberpunk porn movie. Reiko is a shape-changing sex droid from the Genom Corp., who goes around collecting "sexual experiences" by having sex with various people. The corporation collects Reiko's experiences and sells them (in vending machines) as virtual reality chips. But a rival corporation has created its own sex droids to infect Genom's sex droids with a virus, so as to steal their proprietary sexperiences. Dood!

Blade Runner (1982). Daryl Hannah plays Pris, a "basic pleasure model" born on Valentine's Day. She's designed for sex-work in the off-world colonies. She gets retrained as an assassin and uses her amazing acrobatic moves to kick Harrison Ford's ass.

A.I. (2001). Jude Law plays Gigolo Joe, a sex robot who gets framed for the murder of a client. Joe befriends the boy robot David (Haley Joel Osment) and takes him to the ultra-decadent Rouge City in search of the Blue Fairy. And no, that doesn't sound obscene at all. Here's a clip of Jude taking Haley to the decadent metropolis: Circuitry Man (1989). Danner is yet another e-gigolo, a "romeo droid" programmed to provide love and companionship and maybe a little nookie on the side. Danner's programmed to think he's in love, so his female boss can manipulate him into doing her bidding.

Weird Science (1985). This is sort of an edge case. Kelly LeBrock is a sex-bot who manages never to put out. Anthony Michael Hall (playing his usual teenage nerd role) and his friend program a government computer to create a simulation of the perfect woman, and an electrical storm miraculously turns her into a three-dimensional artifact. And then she teaches the boys about life and stuff.

Buffy The Vampire Slayer (1997-2002). When psycho-nerd Warren makes himself a robotic girlfriend, Spike the naughty vampire wants one of his own... except he wants it to be just like Buffy. The resulting bot gets Spike into trouble, but then becomes one of the most valuable members of the Scooby gang. Yet another example of a sex bot who turns into a deadly operative.

Heavy Metal 2000 (2000). A sex robot is programmed to make loud and exaggerated sounds of excitement and climax. She teams up with our heroes to stop the sex lizards. Or something.

Millennium (1989). The John Varley short story and novel include Sherman, a robot who attends to Louise's needs, including her frequent sexual urges. In the 1989 movie, Sherman mostly just provides emotional support to Louise (Cheryl Ladd). (Bah.)
