At first, I cloned sicktim files in kinetic version in my laptop(using ubuntu 16.0.4) from github and changed some parameters in those files according to my lidar. I am using TIM561-2050101S01 lidar. Later, I realized I need to use PC in lab to work with Lidar for long term, I cloned again in melodic version (as my PC is using ROS melodic) and replaced the files with kinetic files that I have changed according to my Lidar configuration.

My catkin_make is successful. But when I use:

roslaunch sick_tim sick_tim551_2050001.launch model:=urdf/sick_tim.urdf.xacro

to launch the urdf file I am getting the following error:

RLException: [sick_tim551_2050001.launch] is neither a launch file in package [sick_tim] nor is [sick_tim] a launch file name
The traceback for the exception was written to the log file

I also removed model in launch command above, but same error persists.

I also used:

roslaunch sick_tim sick_tim551_2050001.launch

same error exists

I also did this:

roslaunch sick_tim sick_tim551_2050001.launch:='$(find sick_tim)/urdf/sick_tim.urdf.xacro'

the error:

RLException: [sick_tim] is not a launch file name
The traceback for the exception was written to the log file

Even, though I am able to find the sick_tim launch file in my PC. I am unable to launch it.

Can anyone answer this question? What is this error means? What should I do to remove this error?

I also tried sourcing the files.

Did you source the setup.bash for your workspace? For instance if your workspace is "~/melodic" did you run "source ~/melodic/devel/setup.bash"?

A quick check would also be, can you "roscd sick_tim"? If not, the package you built is still not on your ROS_PACKAGE_PATH (in which case, you probably haven't sourced the workspace yet).
