HOUSTON — NASA’s Robonaut 2 has no voice but is ready to tell you its story — in 140 characters or less. The prototype robot will travel to space this fall to give NASA a deeper understanding of human-robotic interaction.

Called R2, the robot has started sending updates about its upcoming mission from its new Twitter account, @AstroRobonaut. With the help of its supporting team, R2 will document its preparations for launch and, eventually, its work aboard the International Space Station.

“Hello World! My name is Robonaut 2 — R2 for short,” R2 and the team tweeted this week. “Follow my adventures here as I prepare for space!”

Reporters are invited to NASA’s Johnson Space Center in Houston at 1 p.m. CDT on Aug. 4 to see demonstrations of R2 in action. They can speak with members of the STS-133 space shuttle crew, who will deliver the robot to the station, and engineers who created R2. Interested news media representatives should e-mail Brandi Dean at brandi.k.dean@nasa.gov by noon on Aug. 3.

The public will get the first chance to interview the robot when R2 and its team answer questions submitted via Twitter at 10 a.m. on Aug. 4. Twitter followers can submit their questions to R2 in real time by including the hashtag #4R2 in their questions tweeted to @AstroRobonaut.

R2 will be shipped next month from Johnson, where it was created, to NASA’s Kennedy Space Center in Florida for final testing and packing. It will launch aboard space shuttle Discovery as part of the STS-133 mission, targeted to lift off in November.

Robonaut 2 was created through a joint project between NASA and General Motors that began in 2007. R2 originally was intended to be an Earth-bound prototype, but engineers wanted to see how it fared in microgravity so the robot is being sent to space in Discovery’s cargo bay.

R2 is already the most advanced dexterous humanoid robot in existence. Once in space, it will become the first humanoid robot to reach orbit and the first American-built robot at the space station. Over time, as its creators learn more about operating R2 in space, upgrades and modifications could be made that would allow the robot to assist astronauts inside and outside of the station with routine tasks or those too dangerous for humans.
