Arctic UAVs: FPV VIDEO-sort of

FPV VIDEO-sort of

I still have not downloaded a program that can record the video while showing it in the GCS and a screen recorder (would be nice because it would also record instruments) drops the frame rate of the the video, so that's out. My dad took this on his iPhone and while its not a full recorder it shows what I see when I'm flying.

I am disappointed with the resolution of the camera and after putting it on a regular TV I think the converter is hurting the quality. I am going to keep an eye out on craigslist for a cheap flat screen TV about 20" that has inputs and outputs so I can hook up a recorder to save the flights, or run it back to the computer and record it that way.

Its looking a little cobbed together... I think its time to put it on the CNC machine and hide some cables

Camera

Transmitter

I put the camera and transmitter on velcro so they can be moved forward and backwards to balance the plane.

Acronyms and Terms

· APM- Ardupilot Mega board, commonly includes the IMU shield (also refers to the firmware loaded on the board)

· IMU- Internal Measuring Unit, Blue sensor board on top of the APM that contains a pressure sensor, 3axis accelerometer, a x-y gyro, and a z gyro.

· RTL- Return To Launch, a auto mode where the plane will fly to its take off location and loiter.

· Loiter- A mode where the plane will lock onto its current point and circle around it even in wind conditions.

· GCS- Ground Control Station, a program that runs on a computer to display readouts sent from the plane.

· AMP/APMP- Ardupilot Mega Planner, program that is responsible for loading firmware, flight plans, interfacing with Xplane simulator, and has a simple ground station.

· HIL- Hardware In Loop (simulator), a mode where a flight simulator inputs data to the APM which sends outputs to control the plane in the simulator, used for testing autopilot function.
