@Zachary-Lowell-0 well it work now!
I found these lines on another thread of the forum:

sudo apt-get install voxl-ros2-foxy
sudo apt-get install voxl-mpa-to-ros2
voxl-configure-mpa-to-ros2
source /opt/ros/foxy/mpa_to_ros2/install/setup.bash
export ROS_HOME=/opt/foxy
ros2 run voxl_mpa_to_ros2 voxl_mpa_to_ros2_node

And everything worked first time ! So please put these line directly on the documentation cause I lost so much time with this install !

@Alex-Kushleyev @wilkinsaf Thanks for your answers! Actually, I've done something similar with docker, but I still have a few problems with the data format that mpa_to_ros sends. To address this, I did the following:

I don't know if this is the right way to do it, but it seems to work. Do you have any suggestions for implementing this directly on the Voxl2?

Also, I have a few problems with camera calibrations and the drone model. Do you have any files that contain all the data for the cameras (ToF, tracking, and high-resolution) and a model of the drone that I can use in RViz and Gazebo? This could really help me.

For more context, I'm trying to implement this project for Autonomous SLAM with ROS. Has anyone already used RTAB-Map on this drone? Do you have any advice to solve this problem?

Thank you for your help

@Jeremy-Schmidt Hi,
It's resolved now, in the mean time I had a response from the support.
Have a good day
Julien

@Alex-Kushleyev I sent an email to the modal ai support for the RMA process and after a first response telling me that they'll check it, I still got no news from them and it has been 3 weeks. Do you know some other way to get in touch with the support. My starling is stuck to the ground since and I can't test anything.
Thanks
Julien

@Judoor-0 after that i did an apt autoremove and it deleted almost all my drone... is it possible to get back from it?

here is my voxl-inspect-services

And command like voxl-configure-mpa are not available anymore.

If I flash a new sdk on the starling, does it delete everything that's in /home/root ?

Julien

HI,
I'm trying to upgrade a starlin2 but when I do

apt-update && apt-upgrade

i'm left whith this error and I don't know how to rsolve it :

@tom
Here is a picture of my services :


It happened only the other day, multiple time.
But I've tested the drone again today and ram seems good, never going above 3590MB/7671MB.

Maybe one of my code was running in the back, I don't really know. If it happen again i'll tell you. And send you more precise information on what's running

Thanks for your help.

Hello,
I have the Starling 2 development kit, and during long-term testing, I've noticed that RAM usage increases very quickly (to the point of crashing the drone), even though the drone is on the bench and I’m only connected via SSH without running any external programs. I'm using SDK version 1.3.5. Has this happened before, and how can I clear the RAM to prevent the drone from crashing?

Julien

Setup : Starling 2 , SDK 1.3.5,

@Alex-Kushleyev it was an original screw, I don't know why but when comparing to another it's slightly longer. I'll request an RMA.

Julien

Hi,
I want to test the vio waypoint functionnality, but when starting a mission I get the error : no global position.
How can i give a global position to qgc, knowing i only use VIO.
Julien

@Cliff-Wong Hi,
I'm trying to implement the vio navigation without gps. i'm on sdk 1.3.2 with a starling 2.
When uploading the waypoint to the drone, the global position of the drone isn't reference to the take off point. in fact it doesn't appear at all on the map.
What can I do to fix that ?
Julien

Hi,
I've got a starling 2 with the black motor and today while testing one of the motor started to stop spinning randomly. I checked the wires and everything seems good. I swapped the motor with another functional one on my drone and the same motor didn't worked, so the ESC is good.
So, I swapped the defective motor with another one that i had in stock and put the props on it and this motor didn't work either!
Well, the problem came frome one of the propeller's screw which is slightly longer than usual and come scratching on top of the motor wire and prevent the motor to turn.

So, I need a new motor for my starling.
