Today, the space shuttle Atlantis flew its last mission, after 25 years and 120 million miles. NASA is retiring the craft that recently completed a near-flawless mission to help assemble the Mir Space Station. During its service, Atlantis also flew five military missions and launched robotic probes to Venus and Jupiter.

More humans and robots might be probing space after Atlantis’ retirement, as Japan plans on creating a robot-built moon base in the next five years. It makes sense, as robots are becoming more and more a fixture in the Japanese lifestyle—such as, in the case of the couple who elected to have the “i-Fairy” robot officiate their wedding.

And, recently, Japanese engineers introduced robot teddy bears that giggle when their stomachs are rubbed. The technology behind the bears is said to be similar to the TrueCompanion “Roxxy,” the world’s first robotic sex doll.

An awesome feat of engineering, Roxxy the sex doll speaks four languages, is capable of flirting, and can be programmed with different personalities—she might even be able to help build that moon base. We’re wondering if she giggles when something else is rubbed.
