    @Matthew-Booker Screenshot_20220811-222954_WhatsApp.png
    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 ?

  • modifying voxl-mapper

    @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.

  • modifying voxl-mapper
    H howard

    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

  • Change home position in Voxl-mapper
    H howard

    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?

  • Change home position in Voxl-mapper
    H howard

    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!!

  • Change home position in Voxl-mapper
    H howard

    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?

    Currently I am not in the office, but I remember that the version of voxl mapper was 0.0.5. What could possibly be causing this error? Do I need to update anything?
