The robotic researchers, Erik Billing from Sweden's University of Skövde and Kathleen Richardson from the UK's De Montfort University, have called for a ban on sex robots.
Speaking with Radio Sweden, Billing says he's not opposed to sex toys but rather how these dolls are being developed into human-like objects. He says there is also a danger that the robots could stunt relationship.
"These machines represent sort of an extreme objectification of mainly the female sex and women in general," he says. "Think about what a full-blown doll or robot gives you in comparison to any other sex toy."
He says a greater debate on the topic is needed to examine their effect on society. Billing adds that right now he sees two positions shaping up each time the issue is raised: one is shocked that the machines even exist and the other thinking it's ridiculous that the machines could ever be harmful.
"Maybe, at least, it's not a bad thing that we get these two opinions to meet," he says.
