I start the launch file with the node from the pyhton file, but I do not get back the informations on the terminal. For example when I have the order "print 5", shouldn’t I see the number 5 on the terminal after I launch the file?

Must I only make nodes executable which I create by myself (for example like this: http://www.ros.org/wiki/ROS/Tutorials/WritingPublisherSubscriber%28c%2B%2B%29), or also the nodes which I have downloaded in a package from ROS? Or should the last one are automatically executable?

I tried rosrun map_server map_server testmap.yaml and get the message `[rosrun] Couldn't find executable named map_server below /opt/ros/electric/stacks/navigation/map_server [rosrun] Found the following, but they're either not files, [rosrun] or not executable: [rosrun] /opt/ros/electric/stacks/navigation/map_server [rosrun] /opt/ros/electric/stacks/navigation/map_server/include/map_server` Why it does not work? Do I have anything to do after the installation, before i can start it? Thanks for help! The rosmake map_server does not work right: (The bin folder is empty.)

2015-08-12 14:04:08 -0500	marked best answer	Cannot launch node Hello! I have a problem when I launch the ar_kinect.launch file. I programmed a Phyton code an wrote this line into the ar_kinect.launch: <node name="kinect" pkg="ar_kinect" type="ar_kinect.py"/> The ar_kinect.py file is stored in the bin file. When I execute the launch file I get the following error message: Error: cannot launch node of type [ar_kinect/ar_kinect.py]: Cannot locate node of type [ar_kinect.py] in package [ar_kinect] What can I do? Thanks for help.
2015-08-03 03:09:44 -0500	marked best answer	static transform publisher - launch file Hi. I have different frames which I create with the static transform publisher in a launch file, for example: <launch> <node pkg="tf" type="static_transform_publisher" name="kinect_base_link5" args="0 0 0 0 1.57 0 /frame1 /frame2 100"/> </launch> I work with a kinect and get from the kinect_aux node the actuel angle from the tilted position from the kinect back. (cur_tilt_angle) So my question is, is it possible that instead I write a fixed value like 1.57, I get this cur_tilt_angle in the launch file? Thank you for help. (I use ROS electric.)
