The University of Maastricht in the Netherlands is awarding a doctorate to a researcher who wrote a paper on marriages between humans and robots.

David Levy, a British artificial intelligence researcher at the college, wrote in his thesis, "Intimate Relationships with Artificial Partners," that trends in robotics and shifting attitudes on marriage are likely to result in sophisticated robots that will eventually be seen as suitable marriage partners.

Levy's conclusion was based on about 450 publications in the fields of psychology, sexology, sociology, robotics, materials science, artificial intelligence, gender studies and computer-human interaction.

The thesis examines human attitudes toward affection, love and sexuality and concluded that the findings are just as applicable to human interaction with robots of the future as they are to the relationships between humans of today.
