How the dexterous humanoid astronaut helper Robonaut R2 can be of service while in space.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, Ron Diftler, NASA Robonaut project manager explains to the audience how the dexterous humanoid astronaut helper, Robonaut (R2) can be of service while in space.

R2 will fly to the International Space Station aboard space shuttle Discovery on the STS-133 mission. Although it will initially only participate in operational tests, upgrades could eventually allow the robot to realize its true purpose -- helping spacewalking astronauts with tasks outside the space station.
