Robonaut 2 (R2) is a humanoid robot torso with arms designed and built by the NASA Johnson Space Center Texas. The hardware helpmate has been in low-Earth orbit since 2011, helping astronauts deal with problems both inside and outside the ISS. Now, after its legs are fitted, the robot will be able to take on more responsibilities.




Hurrah, I'm no longer legless

Robonaut's legs aren't as limited as our human limbs; each has seven joints and the "feet" are manipulators that enable the machine to anchor itself while using both hands on complex jobs, and cameras to ensure it gets a solid grip on walkways and safety handles.

Once the legs have been delivered to the ISS, the crew will affix them to Robonaut's torso and begin running through series of software upgrades to its operating system that will allow the robot to be either programmed for day-to-day functions or to act under remote control from one of the astronauts.

R2 has already distinguished itself in both fields. The upper part of the robot has been designed along humanoid lines so that it can use the same tools and instrument controls as its human counterparts, but the new legs will give R2 a much wider range. ®
