8 of the Best Science Fiction Books About Robots

I mean, C-3PO and R2D2 were on my radar before I could even read. And ever since I learned to read, I've loved any book with robots in it. I'm not talking murderous robots taking over the world stories (although those can be fun, too). Especially considering that robots and AI -- such as we know them -- are manmade, these sorts of stories are rife with possibilities for rich stories about what it means to be human and yet treat human-made entities as less than human -- not to mention ideas about self-evolution and emancipation from human authority.
