Nowadays, the FAA is discussing about open the low area for registered flight, so the Drone for Amazon will be the possible. In addition, Amazon is developing its own drone for future delivery method. In this project, we implement automatic piloting system for AR. Drone by tracking a line with on-board camera. This project uses AR. Drone for our implementation of the line tracker because there exist several available SDKs based on Wi-Fi network and two HD quality cameras. For the SDK, YA. Drone from University in Hamburg, Germany is employed and it is combined with Image Processing Technology in order for a drone to track the line. The preliminary results show that a drone can successfully track various types of lines behind a drone, such as straight, 90 degree, crank, circle and arbitrary lines. Using the automatic piloting system in this project, a drone can send something from one room to other room, and eventually deliver an item outdoor
