      Can you put some pieces of duct tape on the floor or something to make it more interesting to the VIO system? Especially since it looks like that floor might be reflective. Random small pieces of tape, like electrical or duct tape, would likely help.

      You can monitor the VIO stability on QGC. Those numbers should stabilize after takeoff, but obviously you want them stable on the ground too.

            thanks for sending, I will pass along to someone more familiar. Was this all working before? Do you know what has changed?

              last week it used to work normally. i did't changed any strange thing, just re-configuration the drone to the factory state. by "voxl-configure-vision-px4 -f" to take again the NED position cuz before that i had config vision lib by "voxl-configure-modalai-vl" and the local poistion is lost.

                  Does this behavior only occur in PX4 position mode? Does it fly in PX4 manual mode?

                    @James-Strawson yes,we only test uav in position mode. we didn't use manual for testing.

                      Please try manual mode. it seems there might be a PX4 parameter mismatch. It would be good to see if the m500 flies properly without VIO.

                      @modaltb Do you have a pointer to the Flight Core factory parmeters?

                      The VIO indoor EKF parameters are here

                        There's a few files (as we use DRY even on params 😉 The procedure to do this is here

                        When you reload the airframe (via these parameters) you'll end up losing calibration and having to go through the calibration process. This is documented here

                        You'll end up loading these, in this order:

                        • configures core airframe for m500 with 4S battery (standard):
                          https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/raw/master/platforms/v1.10/m500_4s_config.params

                        • VIO indoor EKF
                          https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/raw/master/helpers/ekf2_indoor_vio.params

                        • Serial params (to be safe, these should be set by default)
                          https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/mavlink_serial_ports.params

                        • If needed and applicable, radio
