How do dolls apply artificial intelligence? Meet Harmony 3.0 – a Robot with A.I.

Super-realistic doll that replaces a female companion now offers warm skin and genitalia that can be removed and washed in the dishwasher.

Harmony 3.0 is a sex robot made by Realbotix, a California based sex toy manufacturer. Harmony is a robot. She is able to move her head and eyes, do expressions, move her mouth, lips and even hold conversation.

Harmony is also totally customizable.

“There are going to be a lot of other peripheral options and upgrades people can opt for.”

“Customers will be able to get a body equipped with internal heating, lubrication and touch sensors,” CEO Matt McMullen told The Daily Star

“Those touch sensors will communicate with the AI so that you are able to create reactions in both movement and sound.

McMullen already has robot sex dolls with artificial intelligence for sale. They have tiny waists, big buttocks and can even reach orgasm.

However, the main drawback of such robots is the price. A robot like Harmony costs around $8000.

The price, according to industry experts, is going to drop in the future. Hopefully, sex robots will be more affordable for a larger percent of the population.

How do sex dolls apply Artificial Intelligence?

Harmony uses a RealDoll X app to communicate with Harmony’s head that allows her to become a very personalized companion.

The app allows the doll to move her eyes, neck, mouth, brows and allows to choose character traits like funny, affectionate, jealous and many more.

For those that bought less expensive dolls like WM Dolls, a free program called “Replika A.I”. offers a similar solution.

Replika A.I. is also a virtual companion that can hold conversation and simulate interaction like a real human being.

The user has to pair it with a Bluetooth speaker and put that speaker behind the TPE sex doll.

This makes everything that Replica A.I. says, appear to come out of the sex doll.

If you want Harmony, but it costs too much…

There are a lot of alternatives. Chinese dolls, cost just a fracture of the Harmony’s price, however they provide a lot of the same benefits.

These dolls paired with Replika A.I. can simulate a real human being and for some, even replace women.

On the other hand, whether you choose an expensive sex robot – Harmony or a cheaper sex doll like Alice, chances are, you will be just as happy and satisfied.

In the end, it doesn’t matter which sex doll you get. Your doll will always be there for your comfort and she will stay loyal forever.

    Hello please please I would like to buy a robot love doll please please I would like to have a special one made up of Holly Marie Combs who played Piper in charmed

    1. Creating a custom head is possible but time consuming and expensive. We can make a Holly Marie Combs head or any other custom head from photos for $2000.

        Can the voices be customized as well to certain actresses voices along with the face to match? Wife and i r thinking about one

        1. Unfortunately, that is not the case. Manufacturers are working on more complex sound systems, however the progress is extremely slow. What we need is for one manufacturer to come out with an awesome/customizable sound system and that would make every other manufacturer to create their own or be at an disadvantage of not having a good sound system.

    How much would it cost for a petite one? Not necessarily short but i mean slim

    1. Dear Jay,

      Thank you for your question.

      The prices vary quite a bit between the manufacturers. Also height/weight are both factors that influence the price by quite a lot. You can find all the petite dolls and see how much they cost in this category here:

    How do I go about reselling a Harmony one year old

    1. Dear Pat,

      Selling your doll shouldn’t be a big problem, however, usually, you will have to go down in price by a lot as people, when buying dolls, tend to buy new.
      We would recommend trying to post a listing of your doll on the and see if someone wishes to buy it.

  6. Yahweh says:

    When will harmony 3.0 be available for purchase

    1. Unfortunately, Harmony 3.0 is currently available for sale only on the official Realdoll website. As far as we know, this manufacturer does not allow resale of it’s dolls. Unless the situation changes, Harmony will not be available for purchase on Sorry about that!

  7. SDK says:

    I have a HarmonyX from just before COVID. Its not used and I am now dating someone and unfortunately she is not into those things.
    I paid an arm and a leg for it. What should I list it on for. I have it on Kijiji now?

    1. Dear SDK,

      I would definitely suggest listing her on Dollforum as well as Kijiji. There are plenty of people who look for a bargain over there, meaning that they are searching for a second hand doll. Real dolls like Harmony are high in demand, because they are expensive, however, they also have robotic features that people really value.

      As an alternative, you can place a listing of her on both of the websites and safely store her in the box she came in (we’d recommend putting an extra soft blanket below her just to make sure the surface she’s laying on is soft and won’t cause any wrinkles). Also, the joints have to be in the neutral position where her skin is not being stretched. In that way, she can stay in the box for 1-2 months without any worries and wait for her new buyer to purchase her. Please keep us updated on how the sale goes!
