One of the early episodes, they encountered a damaged robot, looked like something from an Asimov novel cover, shiny metal face with almost no features, anyway they repaired it and it befriended Torres and took her to it's 'people', all of em robots, they wanted her to make a power module to power them because they could make everything else they couldn't make new modules so when one of em died they couldn't replace it. She helped em out but then they found out they had wiped out their creators and that there was another identical race of robots who did the same and they were both fighting the war their creators had tried to stop, their ships were very lame though.
