Yes. Many moons ago as a young'in, I remember reading some short sci-fi story about some human astronaut/space explore landing/returning on/to some planet (possibly a future earth)where the machines/robots had taken over. A native (robot hunter gather)had discovered him and his colleague, and promptly proceeded to grab his colleague and dismember him, much as a kid would pull an insect apart. It then put him in his robot backpack and brought him home, possibly as a pet,item of interest, or food. At any rate, our intrepid voyager chronicled what followed after arriving at the robot's home, including an interaction between the robot and his wife where there was some kind of exchange of electricity. I remember our protagonist described it as "sex." If their intercourse produced anything (and why not, it is sci-fi),it would undoubtedly and undeniably be called a robotot.
