Roxxxy, the world's first sex robot

My girlfriend's hot, but she has a built-in cooling system:

n what is billed as a world first, a life-size robotic girlfriend complete with artificial intelligence and flesh-like synthetic skin was introduced to adoring fans at the AVN Adult Entertainment Expo in Las Vegas on Saturday.

"She can't vacuum, she can't cook, but she can do almost anything else if you know what I mean," said her inventor, Douglas Hines, of the company TrueCompanion.

"She's a companion. She has a personality. She hears you. She listens to you. She speaks. She feels your touch. She goes to sleep. We are trying to replicate a personality of a person."

At 170-centimetres tall and 54.43 kilograms, Roxxxy "has a full C cup and is ready for action", said Hines, who was an artificial intelligence engineer at Bell Laboratories before he started up TrueCompanion.

Roxxxy comes with five personalities. Wild Wendy is outgoing and adventurous. Frigid Farrah is reserved and shy. There is a young and naive personality and a Mature Martha that Hines describes as having a "matriarchal kind of caring". S&M Susan is geared for more adventurous types.

Roxxxy costs between $US7000 ($7634) and $US9000 depending on features.
