      @AP123 In portal you aren't seeing anything when you select "Stereo Front Disparity" for example?

          @AP123 What about the "stereo" one itself?

                @AP123 might be worth trying this to see if the voxl-vision-px4 is handling the avoidance data correctly: https://docs.modalai.com/voxl-vision-px4-collision-prevention-0_9/#debugging-collision-prevention

                            @AP123 It's possible, I would take a look here as well for some relevant info: https://docs.modalai.com/configure-extrinsics/

                                        @AP123 Hey there. Are you running VOA against a stereo camera pair or via a ToF sensor?

                                        If you run voxl-inspect-points voa_pc_out and see data, then the voxl2 SDK services are good and generating the correct mavlink obstacle distance points to PX4. If not then there's a configuration issue.

                                        If that is good, then you need to make sure PX4 has
                                        MPC_POS_MODE = Simple pos control or smooth pos control, COM_OBS_AVOID is enabled, CP_DIST > 0 (e.g. 2) and you must have an established home position (or good position from qvio if that is the case). Typically an "obstacle system not ready" is due to the MPC_POS_MODE (I think we default to acceleration-based input).

                                        If all those check out, then it's likely missing a home position requirement in PX4 & not voxl, and we'll need to look that up.
