Hi,

 

Open source autopilots are widely used in the RC toys. I tried 3DR's pixhawk. It seems to be quite okay. There are also other open source autopilots.

The commercial autopilots are always used in commercial unmanned aircraft. They are somehow much more expensive than open source. I’m wondering what are commercial autopilots’ typical advantages compared with the best open source autopilots for conventional fixed wing usage. Could anyone give any hint on that?

 

Best,

Anna

  • The KMZ flight path files failed to load on this forum so I created a screen capture of the flight-path the intrepid FX61 used to create the point cloud. Take note how I glide into the waypoints to minimize motor vibration.

      • So awesome.

  • Cala,

    A few more things. I don't use the built in camera trigger to trigger the photo-bursting but I do use it to test the position of the servo arm vs. PWM value the APM sees. What I do is change "set camera trigger" in the configuration screen of MP and write it to the APM board while servo is hooked up with a 5V power source. I hook up the trigger to output channel 7 (or whatever channel trigger is set for)As soon as I write the new parameter, the trigger changes state. I then write and save the parameter value to other positions with different values for finding the sweet spot for triggering, focus etc. After testing I disconnect the camera trigger and manual activate it with the sequence described prior. You must use opto-isolated outputs 5,6,7 or 8. 1-4 are reserved for output control to the UAV. The APM digital outputs do not have enough power to driver the servo and may cause a reboot to the APM I you try it.
    • Thank's Forest, my Lumix doesn't have a retract lens and focus very fast it's a sport camera but the time lapse is very slow so I'm going to try like you explain, thank's for so detailed explanation.
