This was inspired by the "Robot Tournament" over in Polls, but that seems to be more of a "which robot would beat up all the others?" thing. I'm more interested in discussion. What were your favorite robots from books, TV or movies? R. Daneel Olivaw (Foundation series) It would be a crime if an Asimov robot didn't top the list. I mean without Asimov we wouldn't be having this discussion. Asimov didn't invent the robot (an Eastern European playwright gets that credit), but robots in sci-fi wouldn't be the same were it not for Asimov's works. Naomi Armitage (Armitage series) Armitage is far from great science fiction, but at least it asks a few questions you don't normally get in robot stories, questions like "what are man's responsibilities to its creations if we choose to play God?" Plus Naomi gets a few good lines like "If you don't want us why did you make us?" (I think she was commenting on an anti-robot demonstration.) Marvin the paranoid android (Hitchhiker's Guide to the Galaxy series) This character doesn't say much about human nature, but offers plenty of humorous criticism of the A.I. effort. I can't remember its name, but the A.I. program that makes the "art in a box" sculptures from the Neuromancer series deserves a mention here somewhere. David (A.I.) I only mildly liked A.I., but at least David explores new territory (love). Just about all the robots in Do Androids Dream of Electric Sheep or Blade Runner. The irony is that the robots' torment arises from mankind trying to avoid playing God (and failing). Project 2501 a.k.a. Puppet Master (Ghost in the Shell) Rather than asking what it means to be self aware, 2501 asks what it means to be a living species with a decent chance of survival. It is interesting that he considers death as important as reproduction. Yeah, I know. I didn't mention the robots from Star Trek nor Star Wars. To me the purpose of robots in science fiction is to ask questions about human nature. "How do we define self awareness?" "What are the moral and philosophical ramifications of playing God? Should we play God and create a sentient species?" "How do you construct an adequate moral system? What is an adequate moral system?" Although I love Star Wars and Star Trek, I don't feel that the robots in those stories offers anything new to the discussion. So who do you like? More importantly, why?
