One expert thinks robotics can help people fulfill their sexual fantasies with their favourite celebrities.

London-based Dr David Levy, author of Love and Sex with Robots, sees a future where it will be common to find sex robots modelled on celebrities.

Speaking to the Daily Star Online, Dr Levy said there is a demand for celebrity sex robots.

"You can imagine people saying, 'I've got a sex robot who looks like Angelina Jolie and she's fabulous in bed!'"he said.

He also said celebrities could be set to make a lot of money out of the venture, by consenting to commercialise their image this way.

"If you're Angelina Jolie and there's a company manufacturing a high-quality product, and you're getting a royalty of £1,000-2,000 for each one, you could make even more millions than you've got just by licensing your appearance," he said.

The Daily Mail reported that earlier this year, a graphic designer created a life-like replica of actress Scarlett Johansson, which is not a sex robot but winks and giggles when someone tells her she's cute.

Dr Levy will be speaking at the international conference on sex with robots- hosted by Goldsmiths University- on Dec 19 and 20.

The sessions will focus on a variety of topics, from humanoid robots and teledildonics, which means cybersex toys, to intelligent electronic sex hardware.
