NASA Johnson Space Center's Robonaut has taken its first steps, using a single "spaceleg" to move around outside a simulated space station. The trial confirmed that the Robonaut, operated by a human teleoperator, could climb around the outside of a spacecraft using handholds and plant its foot at a worksite to make repairs or install parts. The Robonaut has also used a set of wheels as an alternative mobile aid, as NASA continues its research into a system that could possibly be used on a robotic Hubble Space Telescope repair mission.

The "leg" test proved the Robonaut's capability for climbing, stabilising and handling extravehicular activity tools and interfaces in space.
