    • RE: voxl 2 rebooting when tflite server is ran

      @Alex-Kushleyev
      the voxl 2 boots, when i click on the voxl-portal to see the tflite detection,that point of time the board reboots.
      at the same time i am getting the hires camera data. and all other camera feeds.
      this is the first time i am facing this kind of error.

      I dont think it is a cable issue, since everything else is working. The same time, I am using VOXL 2 to FC v2 to ESC.

    • tflite server multi modal

      Re: TFLite multiple model execution

      @nickk14 Hey, I wanted to know whether you are running the same tflite server with changes , or you created a custom tflite server and running it parallely. I would like to know whether the changes you have made are open source or not, if yes, could help me out here.

    • offboard- error with voxl2 and FC v2

      Re: Drone losing position / crashing in Offboard mode
      @Eric-Katzfey @Alex-Kushleyev @Zachary-Lowell-0
      Even though earlier I was able to solve the error with help from you, now i am facing the same errors. the odometry is not published on the terminal and the drone is coming down.
      VOXL 2 with FC V2 is used, SDK 1.4.0 and PX4 firmware is 1.14.0dev

      @Alex-Kushleyev @Eric-Katzfey

      The temperature rise is when i run the voxl-camera-server. I tried with turning off and on individual server and as soon as i turn on the camera server temperature rises up by 30 to 40 degree celsius, that is upto 88-90 degree celsius. this affects the performance

      @Alex-Kushleyev Thank you for reverting, I didnt change anything with respect to the fc or ESC, the firmware is the same.
      could you help me with understanding why it was working earlier , it is not now.
      The firmware of the FC is voxl-fpv-dev version, and when i tried to build again it is giving error, and not building.
      I still dont know whether the issue is with respect to FC firmware or ESC

      @zauberflote1 @Alex-Kushleyev @Cliff-Wong Thank you for reverting, I have setted up the openvins server now, the major cause of drift was improper extrinsic value, now the drone is much stable, but still drifting with in a small area, the vio data is fed into fc v2 . can that be an issue for the drifting

    • temperature issue with voxl 2

      Hey @Alex-Kushleyev @Eric-Katzfey

      I am facing an issue of over heating and servers or wifi not working properly. Even with out any flight , a drone that is kept open, causes the voxl 2 board to reach 60 degree Celsius very fast, with in a matter 2 - 3 minutes.
      What could be the reason for the sudden temperature rise.

      I am running with 2 tracking, 1 hires, 1 TOF connected to Voxl2 . along with camera, mapper, openvins, and vision servers.
      The px4 is running on the external flight controller.
      Also while booting itself the flight controller is showing random height as reference in QGC, after rebooting it settles, what could be the reason for this error too.
      please clarify my doubts

      hey @Alex-Kushleyev
      I am facing the same issue again, the ESC is not initialising when connected through fc v2 , i have followed all the suggestions you mentioned earlier. the FC as well as VOXL 2 is powered through ESC.

      @Alex-Kushleyev can you help me with this

      also which is the preferred imu for the extrinsic when I am using voxl 2 + fc v2 + M1073

    • RE: voxl-open-vins-server

      @zauberflote1 I will the imu temp file and remove it for test.
      The ov overlay and map created by mapper, shows that the drone is not drifting in ground test, but in actual test the drone is jumping up and down. i would like to know why this is happening, this is only when when i use tracking camera data, when i use an optical flow that is directly connected to fc v2 the drone is very stable, and collision prevention is also working.

      All the camera where calibrated before the tests and calibration was successful. I have already checked out the obvious issues, and they all are fine, am i missing out something. help me out to get a better position hold and autonomy without drifting of the system

      @zauberflote1 @Alex-Kushleyev @Eric-Katzfey @tom
      I am providing my config file here for your reference.
      the drone contains a voxl 2 board, M1073 camera coax board with 2 tracking camera and 1 tof and 1 hires camers along with one flight core v2 as external fc.

      The drone is losing position very easily. within the few seconds of take off

      @Alex-Kushleyev @tom @Vinny @zauberflote1 @Eric-Katzfey

      My drone is drifting off when i fly VOXL 2 with 2 tracking camera using voxl-open-vins-server.

      I am getting the following warnings on the terminal and i would to get some help get my drone flying without any errors and drift.

      The major drift is when the drone is yawing, it is drifting both is ground test and flight test

    • RE: Sendor suit getting stalled

      @Alex-Kushleyev I had checked the with the command and it did not recognize the hires camera at all and the tracking camera in certain and totally independent conditions. which makes me able to understand what is the cause of error.

    • Sendor suit getting stalled

      Re: CAM_MISSING_STALLED

      @Alex-Kushleyev @tom @modaltb @Eric-Katzfey

      I would like to reopen the query , which i was never able to solve .
      I am still facing the same error. this time i am using the new PMD TOF LIOW , with old tracking camer and old hires.
      The TOF is working perfect but tracking camera is getting stalled. Also this time hires is not at all starting.
