For example , robotic space pods can be sent into locations where humans cannot safely go in order to test for air and ground qualities or to take samples or photographs for future study . Controlling these robotic inventions is a matter of mathematics , and trigonometry plays a large role in this . A simple example is that of the robotic arm . If an astronaut controlling a robotic arm knows the length of the arm and the height of the base that is supporting it , then the study of trigonometry can tell him exactly how to maneuver the arm – in a circular or triangular motion
