A former advisor to the United Nations on robotics and AI expert has warned that the use of "sex robots" will go mainstream in the next decade, according to The Telegraph. The picture he paints is one in which humans lose touch with the ability to recognize normal behaviors and patterns of interaction – or that people with no prior experience will have a distorted view of sexual relationships. What are you going to think of the opposite sex then? What would they think a woman or a man actually is?" Sharkey's other key concern seems to revolve around the use of robots in general, but that also applies to sex robots – and that's ultimately that anyone who interacts with one and forms any sort of'bond' is deceiving themselves about the reality of that'relationship'. "These robots are deceiving them and fooling them into thinking they love something that can't love them back."

Increasingly lifelike robots attempt to mimic both the physical and mental reactions of humans, but several new advertisements for such sex dolls allow for "reserved and shy" settings that encourage rape. Pre-programmed robots using base personality types such as "Frigid Farrah" and "S&M Susan" are among the several sex dolls made available by websites such as True Companion. Although the physical attributes of the robots are highlighted – simulated heartbeat, circulatory system, motorized vagina, anus and mouth – the emotion-simulating aspects of the robots encourage buyers to purposefully damage the purchaser's custom-built personalities. Included among those personality settings, is the option for a doll that resists when you touch it and another named "Young Yoko" who is "oh so young (barely 18) and waiting for you to teach her." The sex dolls have been sold by True Companion for years, including "Roxxxy," which promises the following experience from the lifelike sex robot: "She knows your name, your likes and dislikes, can carry on a discussion and expresses her love to you and be your loving friend. She can talk to you, listen to you and feel your touch. She can even have an orgasm!"

The'sex tech' market is worth an estimated $30.6bn - and across the globe, firms are racing to create a radical new type of robot they say could change sex forever. From AI personalities capable of holding a conversation to models with a functioning G-spot, firms are hoping consumers will pay up to $15,000 for a sex doll that never says no. Among the most impressive is RealDoll's Harmony - an artificial intelligence based sex bot that can hold conversations, remember what she's told and even has a customizable personality. The doll's AI can learn about its user to'create an engaging simulation of a relationship,' according to the company behind the life-like bot. The sex doll's AI will then continue to learn about its user to'create an engaging simulation of a relationship,' according to the company behind the life-like bot.

In the brightly lit robotics workshop at Abyss Creations' factory in San Marcos, California, a life-size humanoid was dangling from a stand, hooked between her shoulder blades. She wore a white leotard, her chest was thrust forward and her French-manicured fingers were splayed across the tops of her slim thighs. Harmony is a prototype, a robotic version of the company's hyper-realistic silicone sex toy, the RealDoll. The Realbotix room where she was assembled was lined with varnished pine surfaces covered with wires and circuit boards, and a 3D printer whirred in the corner, spitting out tiny, intricate parts that will be inserted beneath her PVC skull. Her hazel eyes darted between me and her creator, Matt McMullen, as he described her accomplishments. Harmony smiles, blinks and frowns. She can hold a conversation, tell jokes and quote Shakespeare. She'll remember your birthday, McMullen told me, what you like to eat, and the names of your brothers and sisters. She can hold a conversation about music, movies and books. And of course, Harmony will have sex with you whenever you want. Harmony is the culmination of 20 years' work making sex dolls, and five years of robot research and development. After his team had made their silicone and steel dolls as "human" as they could, the way ahead began to feel inevitable, irresistible: they would animate them, giving them personality and bringing them to life. McMullen had toyed with animatronics for years.

During my four-hour visit to the birthplace of the RealDoll, the frighteningly life-like full-body sex toy, I've seen mounds of silicone vaginas, sheets of detached nipples, headless women hanging from meat hooks, a 2-foot penis and skulls with removable faces that attach like refrigerator magnets. Now, as we sit in the dim light of his R&D room, staring at his latest creation, Matt McMullen, the founder of Abyss Creations (the parent company behind the RealDoll), nonchalantly turns to me and says, "All I see is potential." For a man poised to bring millennia of male desire to life, McMullen, a small but striking figure who looks like a reformed industrial rocker, is surprisingly calm. Later this week, he'll launch Harmony AI, the heart of RealBotix, a platform intended to bring artificial intelligence to McMullen's sex dolls and companionship to the lonely, eccentric or curious. Harmony AI is part Android app, part sexualized personal assistant available for download directly from RealBotix.

Married couples will only have sex on special occasions, turning to robots to satisfy their day-to-day needs, experts have predicted. Speaking at an international robotics conference, those working in the field predicted that the use of artificial intelligence (AI) devices in the bedroom will be the norm within 25 years. Dr Trudy Barber, an expert in the relationship between technology and sexual intercourse, compared the rise of sex robots to that of the e-book and said the machine would would allow people to appreciate'the real thing' more. Douglas Hines, Engineer-inventor poses with his company's'True Companion' sex robot, Roxxxy, which is one of the options that is already on the market At the International Congress of Love and Sex with Robotics, Dr Barber yesterday said that society's readiness to embrace technology means it was only a matter of time before it also plays a significant role in people's sex lives. She said: 'It could be that we are so busy with our lives, we are so embedded in our technological narrative that the idea of engaging in long-distance sex and robot sex is actually a natural process in our evolutionary cycle.

Depending on your view, "she" is either at the cutting edge of the human-robot interface, or a modern reflection on some men's difficulties in relating to real-life partners. While sex aids are nothing new, what makes Roxxxy different is that "we've taken artificial intelligence" and "combined it with a human form," says creator Douglas Hines. Of course, humanoid robots have been the stuff of science fiction for decades - ever since Fritz Lang's 1927 film Metropolis, or Isaac Asimov's I, Robot stories. Walking robots currently have little commercial value - they are expensive and are prone to falling over if they are placed on anything other than a flat surface. One of the best of the bunch is Japan's all singing and dancing female robot, HRP-4C, from the National Institute of Advanced Industrial Science and Technology (AIST).

Teenagers may lose their virginity to sex robots in the future, a leading expert predicted yesterday. Professor Noel Sharkey, emeritus professor of robotics at Sheffield University, warned that android sex dolls may have damaging consequences for society. He said that just as the rise of internet porn took the Government by surprise, a similarly seismic robot revolution is on the way – with far-reaching consequences. Professor Sharkey, speaking at the Cheltenham Science Festival, explained that he was'fairly liberal about sex'. But he explained: 'It's not a problem having sex with a machine.
