FBW idea

Posted by charlie Soppelsa on May 22, 2011 at 3:08am

Hi all

I'm still using NG and looking forward to changing to ACM 2 when it's more debugged.

ACM 2 has various flight modes including stable and position hold like NG, and I see some people are working on a FBW system. I was wondering if it may be possible to have a position hold system were the quad will stay in the same place when there are no stick inputs, and will move in pitch, roll, yaw and altitude when instructed and then stop and stay in the new place when the sticks are released.

Would this make the quad very easy to fly, even for inexperienced pilots like me.

     Would I not be alot easier to add gps  and  a baro sensor to the groundstation for the quad to use a referrence for loiter?

    This would be super easy to do. 2 lines of code in fact.

    Add this to your APM_Config.h to test it.

     

    #define AUTO_RESET_LOITER    1

    Well we have that already in AC code. But as it might sound easy, its not. Position hold is done by relying on GPS and GPS is not so accurate after all. It still moves 2-4 meters. Even those mikrokopters and rest have same thing. Also wind etc turbulence affects on results.

    One special flight mode calles Simple helps a lot of new pilots to steer their ArduCopters. Whe flying on simple, it does not matter which way nose point. If you pull pitch stick down, ArduCopter will "reverse", stick to left and it goes to left and so on. . . So you dont need to care about its orientation.

    Microdrones have this feature as well (and this is a >10k$ system)

    would be nice to see this on arducopter!
