Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Mechanical engineers are typically involved with the generation, distribution, and use of energy; the processing of materials; the control and automation of manufacturing systems; the design and development of machines; and the solutions to environmental problems.echanical engineers work on teams responsible for developing a wide range of products and systems including, for example, space shuttle vehicles, aircraft of all sizes and shapes, automobiles, turbines, pumps, power plants, and factories.
