"In China, King-his Tse, invented in the 500 b. C. a flying magpie of wood and bam-boo, and a wooden horse able to jump. Around year 200 B.C., Philo of Byzantium, inventor of the repetitive catapult, constructed an aquatic robot. In 206 B.C., the first Han Emperor found the Chin Shih Hueng Ti's treasure. It included a mechanical toy orchestra that moved independently. In old Greece, Archytas of Tarento (referenced in [English]] as Archytas of Tarentum, and in some references in Spanish as Architas de Tarento), philosopher, mathematician and contemporary politician of Plato, considered the father of mechanical engineering and precursory of the robotics, in-vented the [w:Screw|screw]] and the pulley, among other many devices. The materials used for the construction of robots were wood (parts with form), iron (fixed structure, supports, hinges), copper (which is mouldable and allowed the construction of thinner parts), leather (cables, footwear) and fabrics. The first models used the application of direct force to make movements, facilitated with sets of pulleys, gears and handles. In this phase the robots were replicas of the human being that made a series of simple movements. The machines began assuming tasks of aid to the man and ended up repelling their conception of the world and animated beings. The mechanics affected the study of nature, spreading to the anatomy science; of which agreed models with that conception were elaborated, such as “De Humani Corporis Fabrica” (On the workings of the human body) from Andreas Vesalius (1514–1564) who conceived the man as a complex mechanical structure."
