    • RE: m500 cannot hovering with VIO algorithm

      Yes, after adding some foam, The UAV now are stable than a bit. Do you think the battery should be problem? Our 3S battery are quite old.

    • RE: m500 cannot hovering with VIO algorithm

      Thank for answer, I've checked the test data above. Here is the list of the /etc/snav# diectory and i checked the calibration.downward.xml and calibration.stereo.xml but both of them are similar as the test data from you.

      • For the camera matrix i've checked in the ~/.ros/root/camera_info folder and they also non change

      Thank for reply,
      I'll try it in the tomorrow. We're in middle of night (GMT +7).

      Also,

      • We never try to flight in the manual mode, only use the position and offboard mode.
      • I don't think the external material was the reason for this issue because we had attached the component in the bottom of the frame closed as much as possible.
        Thank you.

    • RE: m500 cannot hovering with VIO algorithm

      Thank for reply,
      @Chad-Sweet when the first time our test flight with M500 everything is work properly. you can take a look in this link by the video named before reset.
      here

      • But after I reset the drone into the factory set up. It's seem the VIO is work with many vibrations, some time it be acceptable.
      • In the link above I was captured 3 videos and log file of each, for testing manual with VIO.
      • Do I needed to recalibration the camera? I see the data from VIO is quite good when we move the UAV by hand.
      • We were revert the UAV to the original state after that but the result is same.

      actually the test frame is only attach in left and right side of UAV. The purpose of test frame is limits UAV in an area so we can avoid the damage when UAV loss control.
      @modaltb do you have any idea?

      Hi. This is the base floor of us. Pls take a look.

    • m500 cannot hovering with VIO algorithm

      Hello, after I reset the VOXL m500 to the factory setup, i ran to take-off in the position mode but the quality of VIO algorithm is quite bad, the M500 take off then drift so much and cannot hovering, I had tested so many time but the result was still remained.

      I was confirmed the data from local position is quite good by voxl-vision-px4 --debug_odometry. Then I go ahead to check the parameter of EKF2_, there is nothing strange. The radio signal is still good. what's more, in the base floor I used the a big chess board plate for enhance the UAV Vision algorithm when takeoff but it's not work.
      We have attached UAV in a test frame so UAV cannot be damaged in some emergency case.
      How can i solve this issue?
      Thank you

    • About camera configuration for M500 frame.

      Hello, i want to ask about camera configuration. After reset m500 by voxl-configure-modalai-vl and setup again follow the guide. I also re-config voxl-vision-px4 to the factory set-up because it's look like when reset modalai-vl the NED position also lost. When i tried with position mode it seem the UAV flies is not good as well as the first time flight.

      • for voxl-configure-cameras i choose the option 3.

      • Here is some information. i think the config is not same as the manual document.

        -> Did i was wrong? M500 driff so much when tried to flies in position mode.
