Robots, in the popular sense of the term, have been serving as marketing devices for the best part of a thousand years. Though simple and semi-automated domestic machines hail back at least to the first century, the earliest known anthropomorphic robots enter history in the twelfth-century Arabia, when a precocious robotics genius developed an ingenious floating bandstand featuring programmable automata. These metallic musicians would apparently perform music at royal parties.
As manufacturing processes became more sophisticated over the following 800 years, synthetic humans and animals appeared more frequently, from Leonardo Da Vinci's robotic knight to Marvin Minsky's octopus arm, the University of Edinburgh's Freddy research robot and Carnegie Mellon's volcano-climbing robot crab, among many others.
