Male sex robots with bionic penises will be rolled out this year according to the pioneer of pleasure behind the popular female versions that dropped last year.

Matt McMullen, founder of Realbotix, is the man who created Harmony, an artificial intelligence app that syncs up with a robotic head system.

The application enables users to match an AI personality with a humanoid robot head, to create the most realistic sex doll imaginable.

Harmony allowed the android companions to talk, learn and satisfy a customer's sexual desires.

Currently there are only female versions of Harmony avatars and robotic heads - and they cost around £11,000 (NZ$20,810), but Matt thinks there is a demand for male versions.

"We're working on a male version of the robot AI,' Matt told Daily Star Online.

"We'll eventually have a male and a female platform available."

Matt, whose firm is based in San Diego, California, previously revealed he had blueprints to create a male sex robot with a bionic penis.

He said customers will be able to plug the robot in so that it can go as long as the user wants.

On the size of its manhood, Matt said the male sex robots will come in all shapes and sizes.

"There's rebuilding that needs to happen on both fronts to create a male platform.

"We're working hard on that and that's one of the next big things we're looking to get up and running."

World leading AI researcher Dr David Levy told the Daily Star Online that male erotic cyborgs could be more popular than sex toys such as vibrators.

He said: "I'm sure women will find robots equally appealing as men.

"If women are that interested in getting satisfaction from a vibrator, imagine how the same women will feel having a robot they can put their arms round them and having the robot squeeze them."

Matt was scrutinised for objectifying women after he created a female sex robot with 'big breasts' and 'pornstar features'.

But the CEO said he considers his creations more than sex dolls, and refers to them as companions.
