ISS038-E-013710 (9 Dec. 2013) --- In the International Space Station's Destiny laboratory, NASA astronaut Rick Mastracchio, Expedition 38 flight engineer, prepares Robonaut 2 for an upcoming ground-commanded firmware update that will support the installation of a pair of legs for the humanoid robot. R2 was designed to test out the capability of a robot to perform tasks deemed too dangerous or mundane for astronauts. Robonaut's legs are scheduled to arrive to the station aboard the SpaceX-3 commercial cargo mission in February 2014.
