Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Undergraduate degree programs in robotics engineering are offered at some schools where students learn about applying mechanics and math to develop automated machines. Robotics engineers seeking more advanced employment opportunities, such as in management, research or teaching, are required to have a graduate degree.
