Project Demonstration1. An ability to determine the position of the

quadcopter using GPS2. An ability to control the copter using an Android

device over a Bluetooth interface3. An ability to automatically take-off and land4. An ability to fly-by-waypoint using GPS

coordinates5. An ability to monitor the state of battery charge

and relay back to user
