There is a young, naive personality along with a Mature Martha that Mr Hines described as having a "matriarchal kind of caring". S & M Susan is geared for more adventurous types.
Aspiring partners can customise Roxxxy features, including race, hair colour and breast size. A male sex robot named Rocky is in development.
People ordering the robots online detail their tastes and interests much like online dating sites but here, the information is used to get the mechanical girlfriend in synch with her mate.
"She knows exactly what you like," Mr Hines said of Roxxxy, noting that Rocky will also come with personalities.
"If you like Porsches, she likes Porsches. If you like soccer, she likes soccer."

Roxxxy will chat with her flesh-and-blood mate, and touching her elicits comments varying according to personalities.
She is wirelessly linked to the Internet for software updates, technical support and to send her man email messages.
People can customise "true companion" personalities and then share the programs with others online on the company's website, according to Mr Hines.
