Sex dolls are nothing new, but there is rising interest in robots that can be used for sexual purposes, with electronics and robotic companies hastily trying to get them to market.
For instance, Californian company RealDoll plans to sell an "artificially intelligent" rubber sex doll able to talk by 2017.
Then there's True Companion that has been designing what it claims is the world's first sex robot—called Roxxxy—for years. Male sex robots are also in development. Her price starts at $6,995.00 but approaches $75,000.00 for custom designs, the company told CNBC.
Roxxxy "knows your likes and dislikes, carries on a discussion and expresses her love to you and (can) be your loving friend. She can talk to you, listen to you and feel your touch. She can even have an orgasm," True Companion says on its website.
Asked whether sex robots like Roxxxy could have a detrimental effect on society, founder of True Companion and inventor or Roxxxy, Douglas Hines, defended his creation, telling CNBC that she has a useful role to play in society.
"Roxxxy provides physical and sexual pleasure but also provides social interaction and engagement," he said. "It's customizing technology to provide a perfect partner - she's not meant to replace a real partner but is meant as a supplement," he said.
He said the sex robot was a useful addition to society and could have therapeutic uses, such as sex therapy. He believed that, contrary to Dr Richardson's concerns, robots like Roxxxy help to reduce sex trafficking, sexual and domestic abuse. "As long as we're not hurting anyone, there's no problem with it," he said.
