Rtabmap on different PC

edit

Hello,

I am trying to run rtabmap on a different PC. I have the kinect connected to my raspberry PI and am following this tutorial: RemoteMapping

There is only one problem when using the ROS_IP and ROS_MASTER_URI I can use rostopic list and see the topics. But when I want to run:

roslaunch rtabmap_ros rtabmap.launch rgb_topic:=/camera/data_throttled_image depth_topic:=/camera/data_throttled_image_depth camera_info_topic:=/camera/data_throttled_camera_info compressed:=true rtabmap_args:="--delete_db_on_start"

I receive the following error:

Unable to contact my own server at [http://10.0.5.229:41491/].
This usually means that the network is not configured properly.

A common cause is that the machine cannot ping itself.  Please check
for errors by running:

    ping 10.0.5.229

For more tips, please see

    http://www.ros.org/wiki/ROS/NetworkSetup

The traceback for the exception was written to the log file

While I am able to ping my machine and also use rostopic list. Also in the launch file on the page this:

<!-- Reduce the image size, e.g., 2 means "width/2 x height/2".

should be changed to

<!-- Reduce the image size, e.g., 2 means "width/2 x height/2". -->

To avoid errors when trying to launch the file.
