      Hi @Jose-Alfredo-Rosas-Cordova ,

      Sorry for the confusion, "native" meaning nothin special "extra" should be needed when compared to desktop Ubuntu, e.g. --> you should be able to follow this: https://docs.docker.com/engine/install/ubuntu/

      For VOXL1, we needed to do some special sauce for Docker, but VOXL2 it should work like you're used to on desktop (from my experience).

      Hi @Nishkala ,

      With the warning that I've not yet tried in python but I'm sure it will work 😉

      This is the source code for our voxl-inspect-qvio tool, and from there we can see it's looking for a pipe QVIO_EXTENDED_LOCATION
      https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/blob/master/clients/voxl-inspect-qvio.c#L51

      That's defined here:
      https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/blob/master/common/voxl_qvio_server.h#L64

      The other place to look for defines is in libmodal-pipe:
      https://gitlab.com/voxl-public/voxl-sdk/core-libs/libmodal-pipe/-/blob/master/library/include

      This is where the inspect tool consumes data:
      https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/blob/master/clients/voxl-inspect-qvio.c#L259

      Here's where we parse and print the info:
      https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/blob/master/clients/voxl-inspect-qvio.c#L184

      We can specify which stereo camera should be calibrated using,
      'voxl-calibrate-camera stereo_front -s 6x8 -l 0.038'

      @Chad-Sweet

      Hi, I was able to specify front stereo camera using the below command,
      'voxl-calibrate-camera stereo_front -s 7x9 -l 0.02'

      Thank you!

      Hi,

      There are two answers to your question:

      You can pipe depth input from voxl-dfs-server (if you're running stereo cameras) to voxl-mapper, or any other service that you may create that produces depth estimates (i.e. if you had a depth from motion project).

      We absolutely plan to support the tof camera on voxl2, we're working on this right now internally and hope to support it in the next month or two.

      @Nishkala,

      This looks like a version mismatch between the voxl-voxblox you built against and the version you have on your VOXL.

      To ensure the versions match, you need to install the build dependencies from the last release in voxl-cross before deploying to voxl. This can be done by running:

      ./install_build_deps.sh apq8096 sdk-0.8

      instead of

      ./install_build_deps.sh apq8096 stable
