This is a 4-way tie, though I don't think one of these really counts as a robot. Bender from the TV show Futurama, Jenny XJ-9 from My Life as a Teenage Robot, Marvin the Paranoid Android from The Hitchhiker's Guide to the Galaxy series, and HAL 9000 from the film 2001: A Space Odyssey. I'm not sure if HAL can be considered a robot, since he was the computer system running the space ship, but I threw him in there anyway because he is artificial intelligence. Especially since Futurama did an homage to HAL in one of their episodes. x3

I'm really having fun with these Writer's Block things. Three of my last four journal entries have been answers to these.
