An expert has warned sex robots present moral and legal dilemmas.

Professor Robin MacKenzie, of Kent Law School, believes ethics has completely changed due to the increasing developments in artificial intelligence especially with the life-like sex bots.

Speaking to the Mirror Online, Robin said: ''Sex, law and ethics will never be the same.

''Sooner than we think, technologists will create sentient, self-aware sexbots, capable of emotional/sexual intimacy.

''Under existing legal and ethical standards, sex between consenting adult humans is permissible, as is sex between humans and things.

''Humans having sex with other humans who are unable to consent to sex, like children and adults lacking decision-making capacity, is seen as unlawful and unethical.

''Such groups are recognised as sentient beings who cannot consent to sex with interests in need of protection.''

Sexbots are reportedly able to help with erectile dysfunction in the elderly.
