ArduRocket - integration into Mission Planner

I have been coding on the ArduRocket rocket stabilization code, and it's nearing the point at which I need to upload it to the APM unit for testing.  I would like to be able to integrate it into the…Continue

"Stew, I’m not sure that for a guided rocket device you want to be using fins to totally control the attitude. A gimbal device on the main thrusters should allow for stabilisation on vertical flights. If the wind is strong then you might want…"

"Stew, I am curious why you choose to use canards rather than the tail fins for the control surfaces, I recall reading somewhere so I may be remembering it wrong, that another group doing a similar thing found that canards caused a larger change in…"

ArduRocket - integration into Mission Planner

I have been coding on the ArduRocket rocket stabilization code, and it's nearing the point at which I need to upload it to the APM unit for testing.  I would like to be able to integrate it into the mission planner options, but it's not obvious how to do this.  Any suggestions on where to start?Thanks,StewSee More

"OK, here's today's progress.  I chopped even more code out of the build and started adding new code in places.  The big item for us will be the roll/pitch/yaw stabilization routines, so I dove into that.  I removed pretty…"

"We'll do better than that how about LIVE video on Livestream! The Ardusat launch coming up in September (22nd) will be broadcasted LIVE from Team Prometheus Mission Control! :)"

"Tridge  I believe the accelerometers and the gyros all have 3 different settings up to 2000/s and 16G's on the accells. Now I don't know how in the code that can be set but that is something we will have to look into.  Further…"

"There are a few other rocket guy's on DIY Drones. I wont mention names but yes rocket guidance is NOT illegal in the US. I don't know about any other country because it's enough for me to keep up with the legalities in my country.…"

"In some places at least, adding guidance to an amateur rocket is illegal. ( as it goes from legally being a hobby device, to legally being a guided missile ) ... you don't need to have on-board explosives ( or any other deadly nasties) for it…"

"Randy, Yes, now that I'm at least somewhat familiar with the ArduPlane code I need to spend some time comparing to ArduCopter, so that I can understand what's different.  As you say, separating the output mixing would be a good…"

"Tridge, Very good points you bring up, these are exactly the things I need to know about.  What is the G range for the accelerometers?  We have both APM1 and APM2 units to test with.  The orientation of the APM in the vehicle is more…"

"Hi Stewart, What are you going to do about the accelerometers during the initial takeoff? I suspect the rocket will saturate them. That will throw off the attitude estimate from DCM. You'll also need quite different code for the speed. I…"

"You could also base your stuff on ArduCopter instead of ArduPlane...that's what I would do although it's mostly because i'm more familiar with the ArduCopter code.  One small advantage is that it's got the AP_Motors class…"

Hello to everyone on here!  You guys can thank Monroe for getting me involved with this project, he and I have been friends for quite a while now and we think a lot alike.  To make a long story short, we are working on a guided rocket project and the option that made the most sense was to use the APM hardware as the main flight controller since it was essentially usable as-is off the shelf.  However, the code leaves something to be desired.I have only been working with it for about a week, but…See More
