Hello @17146275,

The issue here seems to be that move_bb8_pkg is not a ROS package in your case, but a regular folder. Therefore, you can’t use rosrun in order to execute its scripts. I suspect this is the issue because I cannot see the CMakeLists.txt or package.xml files inside it in the image you shared. You can see here the original contents of the package: https://bitbucket.org/theconstructcore/linux_course_files/src/master/move_bb8_pkg/

Best,
