Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Robotics is the interdisciplinary branch of engineering and science that includes mechanical engineering, electrical engineering, computer science, and others. Robotics deals with the design, construction, operation, and use of robots, as well as computer systems for their control, sensory feedback, and information processing. These technologies are used to develop machines that can substitute for humans.
