NASA and General Motors have developed a humanoid robot called Robonaut2. It is more dexterous and human-like than its predecessor and other, similar robots. NASA hopes to use it for precursor missions to the moon or Mars, or to work side-by-side with astronauts on the space station. GM says the technology could be used in its manufacturing plants or put into its products. In the video engineers discuss the robots importance and demonstrate how it works.
