Hi,
I am trying use VIO to fly my drone outdoors without gps, I am using voxl cam and have connected Pixhawk cube externally. I have followed all the steps, but in Mavlink inspector I am getting x&y odometry values as zero ,whereas it shows z value.What am I missing out? Can someone help please.

@Matthew-Booker
This is the output on voxl cross.but on voxl2 we couldn't run the command for opkg.
Can you please tell the equivalent command for voxl 2 ?

@Matthew-Booker
Sorry for being late, we were trying to build the package again on voxl cross,
We got the following error,
https://docs.google.com/document/d/1C1fZl-i5CzY3OUXER0KUOl3I6TGEhlw1XSsiebbMCr4/edit?usp=drivesdk
After analysis we felt that ceres server package was missing hence we installed it using the instructions provided on the ceres server page. https://ceres-solver.org/installation.html
We even customised the build by using tye command

cmake -DCMAKE_CXX_FLAGS="-march=native" /home/root/ceres-solver

After running make install as seen in above link
We noticed that the libceres.a file was in /usr/local/bin and not in /usr/lib64
Hence we copied libceres.a file to usr/lib64 but we ended up getting the following error, '/usr/lib64/libceres.a: error adding symbols: file in wrong format'
The scenario can be seen in the below document.

Please help us in solving the error
Thanks!

Hello team,
We wanted to modify the source code of voxl-mapper to send z coordinate. We have changed the code and now we would like to build it. We tried building it using voxl-cross but we got the following error

CMakeFiles/Makefile2:340: recipe for target 'server/voxblox_loco_planner/CMakeFiles/voxblox_loco_planner.dir/all' failed
make[1]: *** [server/voxblox_loco_planner/CMakeFiles/voxblox_loco_planner.dir/all] Error 2
Makefile:135: recipe for target 'all' failed
make: *** [all] Error 2

Do we need to use voxl-emulator or something?can you please help us with this.
thank you

Hey, Thank you , that worked really well.

1. Where can we find the 'voxl_mapper.cc' script in the filesystem of voxl?
2. We are interested to provide a 3d goal point rather than only providing goal x,y coordinates with z fixed. Will point to point navigation work if a 3d goal point is provided (i.e. providing x,y and z coordinates rather than only giving x and y coordinates with a constant z) with the current package?

@Matthew-Booker sure, will do that. Can you please elaborate a little on loco_scale_time parameter ? what does that parameter do?
Thank you

@Matthew-Booker No , I have changed it to trajectory

Hey,
So today I tried sending x and y coordinates as mentioned above, we could see the path on voxl portal and the trajectory was sent to voxl vison px4 , however when we switched to offboard mode and pressed follow button, the vehicle didn't follow the path instead it yawed by some angle and went a little forward. What could be the issue?
Thanks!!

Oh okay, That was helpful ,Thank you

@Matthew-Booker will do that, thank you!!

Hello,
I would like to send the coordinates for PLAN TO POINT in Voxl-Mapper rather than selecting in the map. While going through the codes I found this line where the goal_pose is being updated.
So can I use a python script to send goal_pose and when I click PLAN TO POINT, it plans a path to that point?
For this where should I place the python file? How can I find the voxl-mapper package inside voxl?
