Some of you might have read my blog posts about ny autonomous sailboat. It is now time to implement my control algorithms on the APM.
My plan is to start with the APMrover code and replace some parts with my code. There are a few changes that i need
Read more…Hi,
I need to build a wind vane to measure wind angle on a autonomous sailing boat. To do that i need a way to measure the angle of a rotating shaft with very little friction. I just got a continuously rotating potentiometer but the friction in it is
I have an APM1 With some logfiles on it that i really want to keep. With Arduplane 2.5 on it i can't enter cli mode regardless of slider position it just boots even if i press enter three times.
In the attached screen dump you can see what the termin

I have also attached my waypoint file.

Can I use my spare APM with mo additional hardware for X-plane simulations? Or do I need to connect the oilpan and a receiver?Magnus
Read more…First my problem:
When running Mission Planner 1.0.54 (Windown Vista) Nothing is drawn on the maps. Not in the Planning tab or the Flight data tab. I can create WPs etc. but no waypoints shows up on the map. In the Flight data tab the plane symbol and

Stabilizing mode and FBW works great after som tuning of Roll PID. Waypoint navigation was not that successful. The

After a break for a couple of months i downloaded the latest mission planner code and updated the firmware on my APM. Everything works like it should except that i don't get any servo output to the control surfaces in autopilot modes (Stabil

My question is how this could hap
I have run into some problems with the PPM encoder on my APM. The trouble begun when iinstalled the APM in my Twinstar II.
After installation i could not switch autopilot modes reliable and afterinstallation of all servos i the yellow LED started to
In which direction should the APM be installed to get correct imu readings. Servo connectors pointing forward or backward?
I think this information should be added in the manual. (If it's not already in there)

When looking agt the plane from behind and rolling it clockwise, should the rollangle values be positive or negative? I have some problem setting up the plane to turn in the right direction...

Today i made my first testflights with my Ardupilot setup. It almost worked...
The setup:
* The plane is a high wing aileron trainer with a 160 cm span and lots of wing area. Very stable.
* Ardupilot running ver. 25_04.
* No shield.
* x,y and Z sensor f
I just want to get you input on the following idea. Until i have a airspeed pressure sensor i have decided to not attempt to control speed using SOG from the GPS. Instead my idea is do define a fixed "cruising power" that gives my plane a safe cruisi
