For the last few decades, Hollywood has been imagining and showing sex bots. Sex robots in movies date back to Westworld (1973), where Blade Runner (1982) and Ex Machina (2014) evolved more in concept and execution. The design and implementation has advanced to the modification of a Robot who has an eerie similarity to the deceased husband of the character in terms of voice, appearance and certain artificial intelligence of the husband's consciousness.

Sex doll makers have focused on this for several years, but there are just a handful of sex dolls available on the market. Sex dolls are often advertised as a lover to have a chat, a hug and a touch, and to replace the need for a real human intimate partner.

This is a difficult problem to solve and thus a lot of designs are still under production. Most dolls are not fully grown, but they attempt to interact like humans through speech and eye gestures and a few facial expressions. They do tend to be anatomically correct with skeleton and certain circulatory systems like Roxxxy.

Among those available on the market, the Harmony Sex Robot is the one that can conduct conversations, has an orgasm of its own, has adjustable eyes and a skin color. Another similar to Harmony is Samantha, which can communicate with the owner, engage in conversation, and is still under development.
