The Robonaut is a humanoid robot, so it’s a robot that looks very much like a person. It has two arms, similar degrees of freedom, and some complex dexterous hands. The hands are also very similar to what we have on our arms. The goal is for the Robonaut to be able to interface with the same interfaces that the crew uses now, and be able to handle the same tools that they use in orbit. Currently we have an (intra-vehicular activity) IVA version of the Robonaut, so it’s inside the space station mounted to a stanchion that the crew’s been working with. Looking forward to the future, we are currently working on a battery-based power system, as well as a pair of legs. Not so much legs like you and I have, but similar to the arms, with specialized end effectors for grabbing on to fixtures, tracks, and hand rails available on the station. This will set the stage for eventually having a robot that goes EVA [extra-vehicular activity].
