Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Robots are used to perform tasks too dangerous or dirty for humans to perform. Robotics engineers use computer-aided design and drafting (CADD) and computer-aided manufacturing (CAM) systems to perform their tasks. Robotics research engineers design robotic systems and research methods to manufacture them economically.
