2. Introduction In the past, the human labor and the aid of domesticated animals, both gave the efforts to build the earliest societies. When the machines were invented to perform repetitive tasks, like “lifting water and grinding grain”, and mechanics and complex mechanisms were developed, human labor became less important. As a result, more technological advances developed slightly and widely spread. Electronics was a major technological advance that led to the creation of the “autonomous robots” by William Grey in 1948. In 1954, George Devol invented a digital and programmable robot and called it “Unimate”, that later on was used to move hot metal objects by General Motors in 1960.
