Since the beginnings of civilisation man has had a fascination for a human-like creation that would assist him. Man had discovered mechanics and the means of creating complex mechanisms which would perform repetitive functions. Technological advances were slow but there were more complex machines, generally limited to a very small number, which performed more grandiose functions such as those invented by Hero of Alexandria. We are interested in achievement associated with the construction of military robots, space robots, medical robots, etc.
