Robotics engineers are engineering technologists who apply principles from mechanical, manufacturing and electrical engineering to design and test robots, automated systems and new applications.
Some computer and information research scientists study how to improve robots. Robotics explores how a machine can interact with the physical world. Computer and information research scientists create the programs that control the robots. They work closely with engineers who focus on the hardware design of robots. Together, these workers test how well the robots do the tasks they were created to do, such as assemble cars and collect data on other planets.
