ArduCopterMega FBW mode

Posted by Jason Short on February 6, 2011 at 9:30pm

It still needs some work, but I thought I'd share this new flight mode. It's intended to simulate position hold using the stick input to generate a GPS offset from home. The really fun side affect is you don't need to be pointing a certain way to fly in that direction. You just point north and it flies north. To demonstrate that here is a video of ACM flying around with full right yaw. I was able to fully control it in a 5-10 mph wind even though it was spinning. The wind got the best of it for a moment there, but it recovered well. Still a little more work to do before alpha.

    The current version is quite stable. If you downloaded it from the SVN and followed the Readme you could fly it.

    Just treat it as pre-alpha and don't trust it. There seems to be a problem in the RC libraries that causes Motors to spin up briefly in the CLI mode. I rarely connect the battery in this mode, so I've never run across it.

    I was also surprised at how stable it was with the gusty wind...  Great day for flying though!

    Basically pretty similar to the "Care free" mode from Mikrokopter? If so, well done! This thing is just getting better and better!

    Really neat!  I think i'm going to be sick after watching all the spinning in the video though!

    There are still some things about it that are a hack. For instance, the D term had to be 0 because of the stick movement looking like rapid acceleration. I will sort that out but for now I'm flying with on P for Nav.

     

    And yes, with GPS on, your stick defines a 45 x 45 meter space to fly the copter in, centered on home. Release the sticks and it will come home.

    So basically wherever you point the stick, thats where the copter will fly?
