Robonaut R2 tweets from outer space

The first human-like astronaut robot - Robonaut 2 or R2 - has awakened at the International Space Station - and already started tweeting.

"Those electrons feel GOOD! One small step for man, one giant leap for tinman kind," said the robot's first tweet.
R2 was brought to the ISS in February 2011 on board of space shuttle Discovery.
It has been designed to work alongside humans, helping them both inside and outside the station.
Although there were tweets sent from R2′s account (@astrorobonaut) before it "woke up", now its nearly 40,000 followers can rest assured the robot is indeed actively "tweeting" as its circuits are operational.
It is even responding to questions and sending birthday greetings.
R2 weighs 136kg (300 pounds), has a torso, two human-like arms and hands, and wears a golden helmet with a visor on its head.

The "tinman" has yet to get its legs, but for now it will stay attached to a fixed base.

At some point though NASA will supply it with one leg - for climbing through the station's corridors.Eventually, the torso may be mounted on a four-wheeled rover called Centaur 2 for possible explorations of Lunar and Martian surfaces.
