Problem solved,
Thanks anyway

@Alex-Kushleyev

I have an RB5 drone that I plan to fly indoors, but I require very accurate localization. For this purpose, I need a fixed reference coordinate system. For example, I want to designate point A (associated with Apriltag0) as (X=0, Y=0, Z=0). This means that even if the drone flies away and later returns to point A, once it detects the AprilTag, its coordinates should reset exactly to (0, 0, 0) without any error.
Since I plan to fly the drone multiple times along a route from point A to point B and back to point A, I need the system to reliably reset the drone’s position to (0, 0, 0) whenever it sees Apriltag0—even if there are slight changes in the tag's position.
How can I achieve this using the AprilTag as a reference coordinate?
I want to reset T_imu_wrt_vio to 0,0,0, when the drone detect the Apriltag.

@Amin-Bassiri could you please someone answering my question.

Hello

We have 7 drones. By mistake, I changed the PID parameter, and then I used auto-tune PID via QGC. I guess these steps changed the shipping conditions of the drone. But still the drones are fully not stable; how can I get back to the original condition of stability?

Hello,

I would like to use apriltag as a reference (0, 0, 0). I mean, for example, when the drone detects the tag, show it in the "T_imu_wrt_vio (m)" (0, 0, 0) coordinate.
How can I do that?

Hello,

Can I use obstacle avoidance for Drone Model: RB5?

I would like to run the SLAM and create a map on my drone; I tried to follow the guideline on this page https://docs.modalai.com/voxl-mapper/#voxl-mapper but I couldn't run it. I'm using RB5 5G. As I understand, you used Starling 2 for mapping. Is it compatible with RB5 5G? Is there any other document I need to follow?

Hello,
We are interested in purchasing a 3D Lidar scanner and would appreciate any recommendations you may have that are compatible with our drones.

@Eric-Katzfey ok, Thanks, we tested GPS M10 and the problem solved.

@Eric-Katzfey

@Eric-Katzfey i got this error
rb5:~$ px4-qshell ist8310 start -R 10 -X -b 1
INFO [qshell] Send cmd: 'ist8310 start -R 10 -X -b 1'

rb5:~$ px4-qshell ist8310 start

also qshell ist8310 start -R 10 -X -b 1. same error

@Eric-Katzfey I changed, but it seems the problem is the GPS device, because when we change the GPS drone can go to position mode, but we still have a problem with MAG, we have to turn off the MAG, The drone can not go to position mode, and also we have too much drift.

when we set EKF2_GPS_CHECK to 1:

@Eric-Katzfey We tested all seven drones and only two of them are working. However, when we swapped the GPS devices, the working drones also failed to work. This suggests that the issue might be with the GPS devices themselves.
Specifically, two GPS devices work with different drones, but the remaining five GPS devices do not work with any of the drones.
Also when we set the SYS_HAS_MAG to 1, the drones can not fly, so we set it to 0 (all the drones)
it seems we have the hardware problem
What we should do now?

@Eric-Katzfey Yesterday I tested seven drones with outdoor parameters. One of them could fly in position mode, and another could fly in position mode but was drifting. The remaining five drones couldn't enter position mode.

The same drones, the same parameters, and the same environment, but different behaviour.

@Eric-Katzfey Yes, manual and altitude modes work well,

1. I started with GPS+Mag+baro but drones couldn't find the mag, sometimes finding the mag but suddenly losing it.
2. I used VIO but sometimes lost the figures and lost the position.
3. Yes, I loaded the specific parameters file for outdoor, and indoor, I tested all of them and checked all the scenarios, but drones outdoors can't fly in position mode without VIO, and with VIO is not stable.

When I turned on the Mag, I had an error: No valid data from Compass 0

@Amin-Bassiri here is the log file:

Hello,

We are from THI University and currently have seven drones that we intend to fly outdoors. However, we've encountered issues with drifting despite adjusting the parameters for outdoor conditions. The drones are unable to switch to position mode and only operate in altitude mode.

We are facing several problems:

1. The magnetometer (Mag) is not valid.
2. When using VIO (Visual Inertial Odometry), we lose the VIO during yaw movements, and it cannot be reset.
3. If we rely solely on outdoor parameters, the drones cannot fly because they do not switch to position mode.
4. The drones vibrate; we have tuned the PID (Proportional Integral Derivative) settings, but the issue persists.

Please assist us in resolving these issues. We are uncertain why all seven drones are unable to operate effectively outdoors.

Drone Model: RB5
Hardware Version: M0052
VOXL-Suite Version: 1.1.2
PX4 Version: 1.14.0dev

Thank you!
