Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
They provide technical support and make sure robotic programs are working correctly. Robotics engineers also review robotic designs, including cost estimates. This job may can involve supervision of other technicians and engineers. Take a look at the following chart for an overview of how to enter this field.
