There are many different kinds of robots: factory automation systems that weld and assemble car engines; machines that place chocolates into boxes; medical devices that support surgeons in operations requiring high-precision manipulation; cars that drive automatically over long distances; vehicles for planetary exploration; mechanisms for powerline or oil platform inspection; toys and educational toolkits for schools and universities; service robots that deliver meals, clean floors, or mow lawns; and "companion robots" that are real partners for humans and share our daily lives. In a sense, all these robots are inspired by biological systems; it's just a matter of degree. A driverless vehicle imitates animals moving autonomously in the world, a factory automation system is intended to replace humans in tasks that are dull, dirty, or dangerous. The term "robot" itself is anthropomorphic as it is derived from the Czech word "robota," which is generally translated as "drudgery" or "hard work," suggesting the analogy to people.
