Mechatronics (MCT) is a multidisciplinary field of engineering that includes a combination of  systems engineering, mechanical engineering, electrical engineering, telecommunications engineering, control engineering and computer engineering. As technology advances, the subfields of engineering multiply and adapt. Mechatronics' aim is a design process that unifies these subfields. Originally, mechatronics just included the combination of mechanics and electronics, hence the word is a combination of mechanics and electronics; however, as technical systems have become more and more complex the word has been broadened to include more technical areas.
