Robonaut 2: The legless android who is to become the first human-like robot in space

With his gold, metallic head and powerful white torso, he looks either like a creation from Star Wars or a member of an American Football team.
But Robonaut 2, or R2 as he is known, is about to become the seventh crew member on board the next Discovery shuttle launch.
NASA will send R2 to become a permanent resident of the International Space Station later this year where he will become the first humanoid robot in space.
R2 was developed jointly by NASA and General Motors in a joint bid to develop a robotic assistant that can work alongside human astronaut in space.
The 21-stone robot consists of a head and a torso with two, strangely muscly, arms.

Members of the media listen as R2 is introduced. It will be used for microgravity experiments in fluid physics, materials science, biology and biotechnology

Its powerful arms are two feet eight inches long and are powerful enough to carry 20 pounds each in Earth’s gravity
But the robot’s fingers are also extremely sensitive and allow R2 to operate machinery with almost the same skill as a human astronaut.
R2 will launch on space shuttle Discovery as part of a mission planned for 1st November. Once aboard the station, engineers will monitor how the robot operates in weightlessness.
The dexterous robot not only looks like a human but also is designed to work like one.
With  human-like hands and arms, R2 is able to use the same tools station crew members use.
It will also keep people back on Earth up to date with its adventures with its very own Twitter account.
For the time being, R2 will be confined to operations in the station's Destiny laboratory.

R2'S SPECIFICATIONS

Materials: Primarily aluminium with steel, and other nonmetallics
Weight: 23 1/2 stone
Height: 3 feet, 4 inches (from waist to head)
Shoulder width: 2 feet, 7 inches
Sensors: 350+, total
Processors: 38 Power PC Processors
Degrees of freedom: 42, total
Speed: Up to 7 feet per sec

But Nasa hopes that modifications in the future may allow it to move more freely around the station's interior or outside the complex.
However it is never expected to return to Earth.
Nasa and GM have both refused to say how much the robot cost to develop.
‘This project exemplifies the promise that a future generation of robots can have both in space and on Earth, not as replacements for humans but as companions that can carry out key supporting roles,’ said John Olson, director of NASA's Exploration Systems Integration Office.
‘The combined potential of humans and robots is a perfect example of the sum equaling more than the parts. It will allow us to go farther and achieve more than we can probably even imagine today.’
Humanoid robots in space may be as assistants or stand-in for astronauts during spacewalks or for tasks too difficult or dangerous for humans.
For now, R2 is still a prototype and does not have adequate protection needed to exist outside the space station in the extreme temperatures of space.
Testing the robot inside the station will provide an important intermediate environment. R2 will be tested in microgravity and subjected to the station's radiation and electromagnetic interference environments.
Although Space Station crew members will be able to operate R2, the robot does not need constant supervision. It is designed to be set tasks and then carry them through autonomously.

The robot is packed full of processing power and is bristling with sensors

The interior operations will provide performance data about how a robot may work side-by-side with astronauts. As development activities progress on the ground, station crews may be provided hardware and software to update R2 to enable it to do new tasks.
R2 is undergoing extensive testing in preparation for its flight.
Vibration, vacuum and radiation testing along with other procedures being conducted on R2 also benefit the team at GM. The car giant plans to use technologies from R2 in future advanced vehicle safety systems and manufacturing plant applications.
Alan Taub, vice president of GM's global research and development, said: ‘The work done by GM and NASA engineers also will help us validate manufacturing technologies that will improve the health and safety of our GM team members at our manufacturing plants throughout the world.
‘Partnerships between organizations such as GM and NASA help ensure space exploration, road travel and manufacturing can become even safer in the future.’ (mailonline)
