"On the DIYDrone store, I followed the Arduino link because the docs all say things are based on Arduino, you need the Arduino IDE, etc. That link takes you to the Arduino Mega 2560 card - nice blue card, matching the color in the picture of the…"

"I Heart Robotics: appreciate the links. I don't speak Windows, but I'll see what can be done with Mac and Linux. I'm a little leery of taking on a project of such broad scope as you describe, though - may be I should pass on this one, but I'll see…"

"Ken: no code posted yet. Need to get the board mismatch solved first, figure out where this MAVLink code sits (since I can't find anything obviously labeled that in APM).

Once I do get going, I'll post the link to the code."

"Well, I've hit a snag - maybe one of you folks can help with a suggestion. I have my Mega 2560 board, and just received my "ArduPilotMega IMU Shield/OilPan Rev-H" - and the pins don't come close to matching. Board sizes are different as well, so I…"

"Ralph: I can't speak to the ubuntu board - sounds like Garry is familiar with options.
 
I'm still puzzled why there isn't a uSD card socket on the system. A Class 10, 8GByte card would resolve most size issues and consume very little power. It's…"

"I Heart Robotics: I've wandered thru those links before, plus some others that are relevant. I agree that ROS isn't really setup for UAVs, but the interface might provide access to some useful plug-ins.

My only real concern has been to find the…"

"This is indeed the WillowGarage ROS. I'll take a look at these use-cases and get back to you on degree of difficulty. Sending heading, speed, and other sensor-related data from APM to ROS is pretty easy. I haven't studied going the reverse direction…"

Per a suggestion from Chris, I'm working on integrating APM with ROS so that APM looks like an ROS node. I'm a newbie with APM and Arduino, but experienced with robotics in general.I've done the basics, getting the various IDE's running and proving…
