thank you it worked, here is my generic kinect.launch file

<launch>

<include file="$(find openni_launch)/launch/openni.launch"/> <node pkg="nodelet" type="nodelet" name="kinect_laser" args="load depthimage_to_laserscan/DepthImageToLaserScanNodelet camera_nodelet_manager"> <remap from="image" to="/camera/depth/image_raw"/> </node>

</launch>

do I need to modify anything else?

Apparently not, if it worked :)

I seem to remember having this problem, and I ended up using depthimage_to_laserscan.

My launch file ended up looking like this:

  <include file="$(find yertle)/launch/openni.launch"/> 
  <!-- fake laser -->
  <node machine="robot" pkg="nodelet" type="nodelet" name="kinect_laser" args="load depthimage_to_laserscan/DepthImageToLaserScanNodelet camera_nodelet_manager">
    <param name="output_frame_id" value="/scanner"/>
    <remap from="image" to="/camera/depth/image_raw"/>
  </node>

Hey Guys, now I'm trying to run this kinect launch (based on turlebot 3dsensor.launch)

it gets stuck on the last line of the following code:

root@ubuntu:~# roslaunch eddiebot_bringup kinect.launch

**process[camera/depthimage_to_laserscan_loader-9]: started with pid [28526]**

it doesn't show any errors but it doesn't start either, it gets stuck there.

EDIT: it seems that the error is not that the process gets "stuck" the error is that this launch file is not related with the kinect hardware... in other words it works with or without the kinect connected to my computer. any suggestions to fix this? any help will be very apreciated.

thank you!
