ArduPilot code now in beta!

Jordi's finished the first beta of ArduPilot, in anticipation of the board's commercial release. Changes and improvements include:
  • The code is now hosted in a proper code repository (Google Code) for version control and to allow others to contribute to the project. You can find it here.
  • RTL (return to launch) and waypoint modes are user selectable
  • Waypoints have altitude as well as lat/lon
  • GPS parser now returned to ASCII NMEA, for compatibility with any GPS module, 1Hz or 5Hz. Very efficient code will allow it to run at any baud speed the module can support.
  • PID loops used in all control functions
  • Lots of bug fixes and error-trapping inserted

  • Nice way to appoach doubts.
    I would do the same but i'm brand new in this field!!
    I've just bought the transimitter, still waiting to receive it, thinking about first plane and then, at that time, probably the PRO version will be available !!!
    Anyhow maybe it's reated to the fact that "lift force" is proportional to speed, so increasing the speed and keeping the same attitude, the bigger force pulls up the plane.. should work! maybe slowly comared to the horizontal speed, but still...

    All properly trimmed aircraft should rise when thrust is increased and descend with thrust is reduced. The FMA just keeps it level during that process.
  • I asked the same on some other post, and I got an answer, yet I still don't understand it.
    But I've bought Ardupilot just now, so I'm going to play with it :)
  • Hi Chris,
    There's something i didn't understand:
    How can the system control and set the altitude, just acting on propeller and motor speed?
    It's ok if you need to reduce it, but what happend if you have to rise up?
    Is the propeller supposed to be mounted in direction that pulls up te plane nose?
    How are you planning to implement this function in ArduPilotPro?
    Just conceptual curiosity !
    You're doing a really good job !
    Thanks for sharing it !
    Bye fro Italy,
    Enrico
