Robonaut 2, or R2, in 2011 became the first humanoid robot in space. Robonaut 2 was initially deployed as a torso-only humanoid restricted to a stanchion.

A Robonaut is a dexterous humanoid robot built and designed at NASA Johnson Space Center in Houston, Texas. The challenge is to build machines that can help humans work and explore in space. Working side by side with humans, or going where the risks are too great for people, Robonauts expanded NASA’s ability for construction and discovery. The ability to use one’s hands to perform tasks is what we refer to as dexterous manipulation, and the challenge has been to create machines with dexterity that exceeds that of an astronaut in a suit.

The Dexterous Robotics Laboratory at NASA’s Lyndon B. Johnson Space Center (JSC) in Houston, Texas, is working on a development project that includes humanoid robots called “robonauts.” Robonaut differs from other current space-faring robots in that, while most current space robotic systems (such as robotic arms, cranes and exploration rovers) are designed to move large objects, Robonaut’s tasks require more dexterity.

The latest Robonaut version, R2, was delivered to the International Space Station (ISS) by STS-133 in February 2011. The first US-built robot on the ISS, R2 is a robotic torso designed to assist with crew EVAs and can hold tools used by the crew. However, Robonaut 2 does not have adequate protection needed to exist outside the space station and enhancements and modifications would be required to allow it to move around the station’s interior.
