Robonaut 2: The basics
Robonaut 2, which will become the first humanoid robot in space, looks a bit like a boxer's training aid.
The $2.5 million space bot consists of a head and torso, along with a pair of dexterous arms that pack down into a puncher's pose. R2 stands 3 feet, 4 inches (1.01 meter) tall and weighs about 330 pounds (150 kilograms).
R2 is a joint project of NASA and carmaker General Motors. It's the product of a cooperative agreement to develop a robotic assistant that can work alongside humans, whether they're astronauts in space or workers at GM plants here on Earth, NASA officials have said.
The bot is made primarily of aluminum and steel. Its head houses five cameras including one infrared camera in the mouth to provide stereo vision and depth perception. The torso contains 38 PowerPC processors, and R2 carries a backpack that can be filled with batteries or a power conversion system. [Infographic: Meet Robonaut 2]
Each of R2's arms can carry about 20 pounds (9.1 kg), and its hands have articulating fingers and thumbs. The robot, which builds on NASA's work with its first Robonaut project, should be able to use the same tools astronauts on the space station use, agency officials said.
