  • Gage, you can find the info here:


  • does anyone know how to setup the telemetry kit sold by 3drobotics?? help

  • We are working on quad with collective pitch control. Is the ACM output compatible for servo control? We have mini digital servos installed.


  • I used todays download from GIT.

    The loiter mode is very good.

    Agreed that when a code change occurs it is important to be careful.

    I fly into a change as if the copter could have different control and reactions.

    Once confident learning its characteristics it is flown a little more wild:-)

    Even weather can change how a copter flies.

    For those who are that eager and bold, the GIT repository is open to all.

    Think of the knowledge barrier of using GIT to download and the Arduino IDE to upload as a safety feature for the unwary...

  • Great Jason.

    Take your time testing as much as you wish.

    Don't feel the pressure of us eager to test the new code ;)

    Thanks again for your time.

    Those are WP's 

    This is mission2.txt in the tools/autotest/  in the Git tree. The format is QGroundControl's mavlink format.

  • Cool! 

    What where those yellow pins, seen in the video?

    Looking forward to the release. I appreciate the efforts made by you and the team.

    Most of what we're doing is testing everything in the SIM. I've got a test now that runs every WP type in a script and I just got it to fly the most complex mission I could come up with. 

    Here's a video:



    What you can see is the Yaw control. There are a few commands that do things like Yaw 720° or point to home or next wp that were tested as well. You'll also notice that the order of execution has changed so conditional commands wait until the prior WP has been reached, not just loaded. This makes mission scripting much more user friendly.


    Another feature that was tested heavily is the dynamic writing of WP's to the copter in flight. You can fly your pattern and click CH7 to save the WP. Then, enter Auto mode to fly the pattern automatically!


    Alt hold has also been improved, and may require some PID Tweaks for users. Hopefully not, but we'll see.


    The rest of the flight controllers are all the same so current PIDs will not need to be changed.


    I'm planning on releasing it tonight or tomorrow morning.




  • switch loiter mode is only the way for the quad stay on the gps position, or before we must define loiter point with a another switch like channel 7 ?

Hi,Im working on a autonomous drones and im using JETSON NANO and flight controller PIXHAWK .Im able to control my drone by giving rc commands on the MAVLINK terminal itself by connecting it with PIXHAWK but now i want a python code from which i can do some operations like:takeoff,left ,right,forward,backward…and i am not using GPS…Can anyone please help me…

Will AHRS_ORIENTATION=8 for Arducopter 3.2.1 on APM 2.5 using a traditional Heli

I have been Reading Chris Olsen posts and watching his videos on Arducopter with traditional Helis using a Pixhawk.I have inherited an older Trex 450 heli with the old Align 3G FBL hardware.  The FBL controller appears to be bad.  So I have an old APM 2.5 without a compass or GPS on board.  I just want to replace the failed Align 3G FBL system with the APM.Now I have to mount the APM under the skids on the heli so the APM will be upside down.I have Two questions.1)  Is the AHRS_ORIENTATION=8…

Maximum number of Lidar for Object Avoidance

Hi all,I'm setting up my PX4-based quad with ST VL53L0X Lidar sensors (I currently have three) and I noticed that line #24 of the current Rangefinder library (here: https://github.com/ArduPilot/ardupilot/blob/master/libraries/AP_RangeFinder/RangeFinder.h#L24) has the maximum number of sensors set to 10 (ten). Am I understanding this correctly? And has anyone ever tried to setup this many rangefinders (or anything close) with any measure of success?Any input/advice will be greatly appreciated.
