    Hello,

    I am trying to run GPS denied navigation using VIO. My hardware setup is

    Flight Controller: CubeOrange
    PX4 version: v1.14.3 (Stable)
    Companion Computer: VOXL 2

    I am trying to use offbaord mode and do navigation, but the problem I am facing is, whenever I switch to offboard, the drone crashes, and it is always in only one direction. It always tilts to the rear left of the drone and falls down.

    Initially I used an optical flow sensor for position hold, later I tried position hold only with external vision and position hold is very good, I can navigate seamlessly around using RC in position hold only with external vision, I tried fusing both EV and OF, position hold was good, but the offboard problem is there even with both EV and OF fused together.

    I have attached the logs below for your reference.

    https://review.px4.io/plot_app?log=e4c9f0f3-df81-4d49-94f0-a9d5b06037c1

    I have switched to offboard mode twice, one is near 6:54:00 and another time is around 7:11:00 for the above log.

    For this log, I have switched to offboard at 1:30:00

    @Eric-Katzfey @James-Strawson Can you please help me with this? Thank you.

    I have already asked in the PX4 forum, and they said that the setpoint is set to 0,0,0. How do I change it so that the setpoint updates with current position and is not 0,0,0?

    When I do listener for setpoint in mavlink console this is what I get

    nsh> listener vehicle_local_position_setpoint

      @Jetson-Nano What is figure_eight_move_home set to in your configuration file for voxl-vision-hub (/etc/modalai/voxl-vision-hub.conf)?

        @Eric-Katzfey It is set to true.

        I have a starling and have verified the parameter with that system also.

          @Jetson-Nano So the figure eight works fine on the Starling? But not on the drone with the Cube Orange using VOXL 2 as a companion computer? What if you takeoff straight up, hover at about 7 or 8 feet altitude, then go into offboard mode. Does it still do the same thing? Is the drone with the Cube Orange much larger than the Starling?

            @Eric-Katzfey The test I'll do and let you know, but the drone with cube orange is bigger than Starling and the extrinsics for the drone has been changed with respect to the modified build's CG.

              Hey @Eric-Katzfey , I tested it in all directions and the drone is going towards the home, but not to 0,0,1.5 but it's going down to 0,0,0. Wherever I take off and navigate and then switch to offboard, it'll try to go to 0,0,0. I tested it with 1m and 2m altitude and still the same. I also tested it right above the origin, it went straight down.

                @Jetson-Nano I'm not sure why it would do that on Cube Orange. It almost seems like it is doing RTL instead of starting the figure eight. The Starling is running our fork of PX4, not standard PX4. You could build our fork and try it on the Cube Orange to see if that makes a difference.

                    @Jetson-Nano No, you would need to download the source and build it yourself.

                      @Eric-Katzfey I tried using the modalai forked repo in the cube and this is the outcome, when I switch to offboard it is still going to home but not like crashing how it was previously, but goes near home and hovers very close to the ground, and I get autopilot disengaged and switches to land mode and lands.

                            @Jetson-Nano I'm guessing that you don't have an odometry mavlink stream setup so the Cube Orange isn't sending out vehicle odometry mavlink packets that the offboard mode needs.

                                @Jetson-Nano I would recommend reading through the PX4 documentataion on Mavlink messaging. It discusses how to enable streams. https://docs.px4.io/v1.14/en/middleware/mavlink.html

                                    @Jetson-Nano The command would be something like mavlink stream -r 30 -s ODOMETRY -u 14556 and would be added to one of the startup files.

                                      @Eric-Katzfey The documentation explains how to send custom mavlink messages, but odometry is not a custom message and isn't it streamed by default in your forked PX4?

                                        @Jetson-Nano The command is the same regardless of whether the message is custom or not. Another thing you can do is enable some of the debug flags available with voxl-vision-hub to see things like which mavlink messages it is receiving and which mavlink messages it is sending out. There are a variety of flags to choose from and that would help to figure out what is going wrong.
