Humanoid Robot hitching space ride on Shuttle Discovery

HOUSTON — To call NASA's Robonaut 2 the silent type would be an understatement.

The first humanoid robot headed for space is no chatty C-3PO. In fact, when two red-shirted NASA handlers rolled R2 — short for Robonaut 2 (not R2D2) — into the press area here at Johnson Space Center, the process was so quiet I didn't even notice.

Which made looking up from my notes a bit of a shock. At 330 pounds (almost 150 kg), Robonaut 2 is a big piece of machinery, and he (it's almost impossible not to think of it as a "he") looked rather intimidating looming across the room like a boxing dummy in a spacesuit.

The robot's "tucked and ready for launch" position only exacerbated the effect. With his bulky arms pulled into his chest, R2 seemed ready to throw a punch.

But Robonaut 2 isn't a fighter. The robot, developed by NASA in partnership with General Motors, is designed to help astronauts with chores and repairs aboard the International Space Station. NASA plans to launch R2 to the space station next week aboard the space shuttle Discovery, along with six flesh-and-blood astronauts and a cargo pod that eventually will be used as a closet on the orbiting lab.

This Robonaut graphics gives you a glimpse of what the robot is expected to do.

According to developer Rob Ambrose, the acting chief of the Automaton, Robotics and Simulation Division at Johnson Space Center, making sure Robonaut 2 can't hurt anyone was the primary goal of the development team.

"When a person steps in the way and interferes with it, nothing dangerous is going to happen," Ambrose told reporters Oct. 21. "The robot will just pause. And if you hit it really hard, it will turn itself off."

Okay, so I didn't have to worry about R2's left jab.

In fact, the model I met was a prototype, Robonaut 2A. He is mechanically identical to Robonaut 2B, the version that's packed and ready for the launch. The only things different, his handlers told me, are the materials he's made of.

Materials are important aboard the space station. They can't be flammable, for one thing, so Robonaut 2A's soft Lycra and neoprene covering was replaced by fire-resistant spacesuit material for the ISS-bound model. Some of the R2B unit's electronic components are space-friendly, as well.
