      Hello everyone.
      I'm configuring a Starling 2, which I can't get to be able to detect obstacles. When I activate the voxl-dfs-server service I see that it is active but not running.

      When I access the service, I see this:
      695d48ea-0f4e-4376-9a96-7667c861f7ea-imagen.png

      When running the voxl-configure-mpa command I get this:
      6417abaf-fc90-431d-948c-93957cdd51ac-imagen.png

      And the list of available pipes are:
      c86d1aad-0865-4f1b-ab8a-72427e97fc22-imagen.png

      I understand that the voxl-dfs-server is looking for the stereo_rear and stereo_front cameras, but the Starling does not have them - the ones I understand it has are Tracking_front, rear and down.
      How can I change that setting? How can I make Starling 2 avoid obstacles?

      Thank you so much

        @valvarez Is there a way to change it manually in code?

          @valvarez Starling 2 uses the TOF sensor, not stereo cameras, for depth information.

            @Eric-Katzfey I'm having the same issue on the VOXL Starling, the /etc/modalai/voxl-dfs-server.conf file is set to use the rear and front stereo intrinsics.yml and extrinstics.yml which don't exist due to what you just mentioned. Is there a specific setup/files we should set the voxl-dfs-server.conf to use ?

              @JoeAR_21 DFS is Depth from Stereo. Starling 2 does not have stereo cameras so cannot use DFS. Starling 2 uses TOF for depth information instead.

                @Eric-Katzfey Is there an existing service/configuration for collision avoidance on these platforms or do we have to implement our own using the TOF sensor data?

                  @JoeAR_21 voxl-vision-hub handles VOA, not voxl-dfs-server

                  You can see the tof callback function in voa_manager here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-vision-hub/-/blob/master/src/voa_manager.c?ref_type=heads#L380
