best way to just get pitch data from arduimu
i would just like to send only pitch angle data from arduimu to another arduino
my understanding of code is poor
i would like to know which of the following pieces of code i need to load onto the imu board to achieve this task?
which piece of code do

I uploaded Ardupilot_2_6 to my ardupilot wich has ArduShield and ArduIMU board, but I can get the GPS LED to lock in,
The BLUE LEDs on the Ardupilot, Ardushield keeps blinking, the IMU board only has the GREEN LED Steady and the YELLOW LED Steady, no
Read more…Transmitter Advice
I am just starting out (in the planning stage) with UAV and FPV flying. I have been looking around at the equipment I would need and I have run into one conundrum: I need a transmitter/receiver pair for control, telemetry, and video. From what I have
Read more…What other common frequencies are offered for FPV Video?
I have 2.4Ghz RC and 900Mhz Xbee. I'm looking for something below the 1000Mhz range to allow more distance, sacrificing quality.
Read more…This is the future.......
Hi guys,
I always knew that rapid prototyping has a big role to play in the future of next generation UAV,s . Here is a link to a company using Stratasys FDM technology to make gimbal mounted video cameras......I can't wait to see the first complete
Read more…Z sensor schematic
I've decided to build a UAV from scratch using thermopiles to determine attitude. I already have an xy sensor from FMA, but I don't have a z sensor. I do have two thermopiles to use. I'd rather not calibrate every time I want to fly or risk weathe

hello, i need help on arduino pro mini microcontroller- 3.3v/ 8 Mhz.
can anyone please help me to tell me the function, detail of the microcontroller.
tell me about the analog to digital function.
thanks
Problem maintaining pitch when accelerating / decelerating.
I just finished up some initial flight tests using the ArduIMU+ V2 in my Skywalker airframe.
This was my first flight tests using IMU stabilization insteed of thermopile sensors. After some PID adjustment I have nice and stable stabilization of the ai
PARKZONE Radian
Ok I have been working on a design for an airframe for my UAV. But, I have an opprtunity to purchase a Parkzone Radian RTF.
Any opinions on if that would be suitable for a UAV? I know the prop is up front, but I think for my use, I can work around tha
no sat fix with UBLOX and 2.6 code
hello, i need a little help for this problem....
i use ardu, shield V2, ublox gps, xy and z senosor.D13 is disconected.airframe is motorglider with v-tail ! (libelle A380)
i make my first fly today in stabilize-mode.the airspeed i set to 0 for testing
question on the ublox gps and adapter
I've got maybe a stupid question...
if I'm getting a ardupilot mega and a ublox gps do i need the ublox adapter for the gps to work with the shield? I know the shield has a EM406 connection, but what about a backup battery and other feature that this

coupling control
Dear all,
I am researching flight dynamic for coupling control(lateral and longitudinal control) using AeroSim software.
I can handle decoupling control for UAV.I u need I can help u.Ready .
May I know how to consider the inertia effect for UAV airpla
Calibrate mode
IDEA: add a mode in Ardupilot 2.6 that will automatically tune PID gains and trim the servos while in flight. (Calibration)
Is there enough attitude and position information to do this? In theory, we want a relationship between servo positions and a

I was just reading the code to try understand how auto landing and takeoff works and just wanted to check if i understood it correctly?
Auto Takeoff
You set the desired take off alt (say 200m), and servo pitch (say 20deg), and autopilot will stick to t

FAA and UAV vs FPV
First off i want to say i am not looking for a loop hole i am just trying to figure out what the rules are.
from what i read the FAA as set some guide lines for UAV to fly without a COA
they are
1) Stay below 400ft.
2) Maintain a "pilot in control", wh
UAV Flight Model Validation, Trim and Linearization using Matlab
In case anyone here is using Matlab and Simulink to test or develop UAVs and UAV autopilots I am posting a link to a new flight dynamic model SFunction for use with Simulink- http://jsbsim.sf.net/JSBSimSFunction.zip
The project enables any JSBSim fli
Read more…Shield or no Shield??
Hello All,
I've seen several posts lately with comments regarding the use of the shield, or rather the lack of the shield in conjunction with the IMU. It would seem most of the Beta testers are not using the shield. I have aslo read comments that the
Worth a try?
I'm really fascinated by the idea of having my own UAV in the air. But I'm not only wondering where I should start but if it's worth a try.
Aims:
- Building a quadcopter
- Equip it with a camera
