Revision history [back]

I figured it out on myself:

gmapping_demo.launch includes a 3dsensor.launch file, which starts openni and this does not find any connected kinect (because there is no connected..).

So i just have to remove this lines from gmapping_demo.launch

  <!-- 3D sensor -->
  <arg name="3d_sensor" default="$(env TURTLEBOT_3D_SENSOR)"/>  <!-- r200, kinect, asus_xtion_pro -->
  <include file="$(find turtlebot_bringup)/launch/3dsensor.launch">
    <arg name="rgb_processing" value="false" />
    <arg name="depth_registration" value="false" />
    <arg name="depth_processing" value="false" />

    <!-- We must specify an absolute topic name because if not it will be prefixed by "$(arg camera)".
         Probably is a bug in the nodelet manager: https://github.com/ros/nodelet_core/issues/7 --> 
    <arg name="scan_topic" value="/scan" />
  </include>
