What could be better than a real human looking robot in space with the initials R2!! I am sure that there was a genuine technical reason for the name, but if you had the chance then you know that you would too! Although it does look a bit more like C-3PO :-)
NASA: "Robonaut not only looks like a human, but it also is designed to work like one. With human-like hands and arms, Robonaut is able to use the same tools station crew members use. In the future, the greatest benefits of humanoid robots in space may be as assistants for astronauts during spacewalks".
