ArduCopterMega on a Guai 330s



ArduCopterMega, the next version of the official ArduCopter code, is flying well and will bring full UAV navigation to ArduPilot by syncing it up with the APM codebase. Right now Jason Short is testing it on different airframes. The video above is it running on a stock Gaui 330s frame, with default settings. Late in the video Jason tries some different PID gains, but you'll see there's a bit of oscillation and they're not as good as the default. Awesome to see that the code can handle quads of such different size (the Gaui 330 is about 60% the size of ArduCopter) with the same standard settings.

    Some ESCs have a minimum low threshold for arming. If your low throttle PWM is not low enough they will not arm. Try trimming down your throttle and try again. You will need to setup your radio in the CLI again.

    This is an ESC problem. Either your battery is low or your throttle output may not be low enough to trigger the ESCs. Try trimming the throttle down, re-set up the radio and try again.

    I got Chri's Gaui up and running with just a minor change in the PID. Im not sure you even need to change the PID now. Maybe just up or down the kD term.

  • in answer to his question, yes it is possible to cut someones finger off with a quad...

     

    we almost had a casualty on our 3rd year uni project

    First pictures of ArduCopter Hexa (Bigger). Landing gears will change in future frames. This is still beta frame and after few more finetunes has been done, we can start make them more publically available.

    @eduardo, 

    What part are you talking about? The first half or the second half?

  • wooble ... wooble ... and more wooble.

    the code continue with same OLD problem.

    i dont know how many people are flying this poor stable code.

    We're getting close to a public alpha. We need to get more flights under our belt and better documentation. I'll also have better support for changing the PIDs in the CLI soon. I set up an issues list on google code, but the support wiki is not quite there.

     

    I think we could offer a public alpha soon once these things are done, but I dread the support issues! I guess it comes with the territory. 

     

    Long term, my plan is to have it fully in sync with APM as soon as the trunk stabilizes to inherit GCS and Mavlink functionality.

    Jack, we don't recommend that anyone other than the dev team use ACM at the moment. It changes by the hour and is not fully documented. The dev team can't answer any questions about how to use it until it's released in beta.

    Sarawuth: we use a 3s 2200 battery. But remember we're using the alpha ACM code, not ArduCopter RC2. It's got a totally new control method.
