Hi.

So I use the openrobotino catkin package and if I do:

roslaunch robotino_node robotino_node.launch hostname:=172.26.1.1

I get:

... logging to /home/robotino/.ros/log/14d5aee0-0b63-11e4-a7b5-001377acf23d/roslaunch-tracking-R560-3803.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt

Now I have looked in the launch file:

<launch>
  <arg name="hostname" default="172.26.1.1" />

    <node name="robotino_node" pkg="robotino_node" type="robotino_node" output="screen">

        <param name="max_linear_vel" value="0.5" />
        <param name="min_linear_vel" value="0.05" />
        <param name="max_angular_vel" value="3.0" />
        <param name="min_angular_vel" value="0.1" />
<!--        <param name="downsample_kinect" value="true" />
        <param name="leaf_size_kinect" value="0.04" />  entfernt da KinectNode nicht aktualisiert-->
        <remap from="robotino_joint_states" to="joint_states" />
        <!--remap from="image_raw" to="image"/-->
    </node>

<!--

  </node>
-->

<!--

    <param name="hostname" value="$(arg hostname)" />
    <param name="cameraNumber" value="0" />
  </node>
-->

    <node pkg="robot_state_publisher" type="robot_state_publisher" name="robot_state_publisher" output="screen">
        <param name="publish_frequency" type="double" value="20.0" />
      </node>

<!--
  <node name="robotino_mapping_node" pkg="robotino_node" type="robotino_mapping_node" output="screen">

  </node>

-->

    <!--node pkg="tf" type="static_transform_publisher" name="laser_link_broadcaster" args="0.12 0 0.025 0 0 0 base_link laser_link 50" /-->

      <param name="robot_description" textfile="$(find robotino_description)/urdf/robotino.urdf" />
</launch>

The robot_state_publisher is already used, so why the warning about the deprecated state_publisher?

I have already changed the URDF in the Catkin Workspace before, when I used a joystick to drive the Robotino around (and it worked, but I can't post how ... (more)

The issue was resolved, turns out there was another robotino_node package on the path that was resolved first, and this incorrect robotino_node package had an incorrect launch file. Take away lesson: always check the ROS_PACKAGE_PATH.
