As I start a new novel project that involves robots, I'm just curious about how the rest of you feel about the concept of the robot: Concept born of the Industrial Revolution; evolution ranging the gamut from simple mechanical toys, to sophisticated simulacrums, to human-looking substitutes; techno-social analogue to indentured servitude; psychological measure of consciousness and sentience; physiological symbol of mortality, evolution and of life itself.

Any opinions as to the handling of robots in literature... what you'd like to have seen, or wish you hadn't... areas that you feel were largely missed... etc?
