I'm trying to run


within a .launch file and I don't know how to specify the path

I tried something like the following but it didn't run.

<node pkg= "ORB_SLAM2" type= "RGBD" args= "<path1> <path2>">

My example:

    <include file="/home/mesa/catkin_ws/src/mavros/mavros/launch/px4.launch"/>
    <include file="/opt/ros/kinetic/share/freenect_launch/launch/freenect.launch"/> 
    <node pkg= "ORB_SLAM2" type= "RGBD" args= "/home/mesa/cavedrone/ORB_SLAM2/Vocabulary/ORBvoc.txt /home/mesa/cavedrone/ORB_SLAM2/tcp_rgbd/bin/kinect.yaml" >


The error I get

Invalid roslaunch XML syntax: mismatched tag: line 6, column 2

Something like that should work. Please edit your question to include the exact launch file and the error message that you get when you try to run it.

The error tells you the problem

Invalid roslaunch XML syntax: mismatched tag: line 6, column 2

Take a look at your node tag, it's missing the / at the end. Change it to

<node pkg= "ORB_SLAM2" type= "RGBD" args= "/home/mesa/cavedrone/ORB_SLAM2/Vocabulary/ORBvoc.txt /home/mesa/cavedrone/ORB_SLAM2/tcp_rgbd/bin/kinect.yaml" />

Note how I added the / at the end of the node tag.

Thank you! Also as a note for others I needed to add a name so I had something like name = "foo" into the line for the launch file to run.
