[ros-users] cannot find state publisher error

[Yeon Grace Lee]

In attempts to relocate the package to another directory, I have created a
new rospackage and copied over the state_publisher.cpp file, my urdf file
called model.xml, my launch file and the meshes folder that holds stl files.
Launch file has been edited to reflect the path change. Copying over these
files have created an error when a launch my launch file. It cannot locate
the node of the type "robot state publisher". The error is copied below:
