Hey, I am having the same problem. Did you find any solutions? Thanks ! :)

Best,

Gabe

Hi, I am trying to use RTAB-Map on my clearpath Jackal robot (am reading its topics through the same wifi). I am not using OpenNI because my robot and ASUS Xtion rgbd camera have already been set up to publish the camera topics (as shown what i get after I type in rostopic list):

/camera/camera_nodelet_manager/bond
/camera/depth/camera_info
/camera/depth/image
/camera/depth/image_raw
/camera/depth/image_rect
/camera/depth/image_rect_raw
/camera/depth/points
/camera/depth_rectify_depth/parameter_descriptions
/camera/depth_rectify_depth/parameter_updates
/camera/depth_registered/camera_info
/camera/depth_registered/image_raw
/camera/depth_registered/image_raw/compressedDepth
/camera/depth_registered/points
/camera/depth_registered/sw_registered/camera_info
/camera/depth_registered/sw_registered/image_rect
/camera/depth_registered/sw_registered/image_rect_raw
/camera/driver/parameter_descriptions
/camera/driver/parameter_updates
/camera/ir/camera_info
/camera/ir/image
/camera/rectify_color/parameter_descriptions
/camera/rectify_color/parameter_updates
/camera/rgb/camera_info
/camera/rgb/image_raw
/camera/rgb/image_rect_color
/camera/rgb/image_rect_color/compressed

Whenever I run roslaunch rtabmap_ros rgbd_mapping.launch rtabmap_args:="--delete_db_on_start", it takes long for my RTAB to open up, and when it does run, I get the following on the Progress dialog of the RTAB GUI when I click on the Download all clouds button (looks like a refresh button) and I select any of the Options:

17:42:11 Downloading the map (global=false ,optimized=true)...
17:42:14 Downloading the map... done.
17:42:14 [ERROR] Map received with code error 1!

Meanwhile, the terminal keeps displaying:

[ WARN] [1464793454.065524286]: TF_OLD_DATA ignoring data from the past for frame camera_rgb_frame at time 1.46479e+09 according to authority unknown_publisher

Possible reasons are listed at http://wiki.ros.org/tf/Errors%20expla...

Anyone know how I might be able to fix this? Thanks for the help! :)

Hey, I would like to ask for help on using my ASUS Xtion camera on my Clearpath Jackal with openni or openni2. When i turn on the jackal and try to view raw image data, I can view an image very well. The problem is that when I try to open openni and openni2, the following error appears:

[ INFO] [1464705771.982015207]: No matching device found.... waiting for devices. Reason: std::string openni2_wrapper::OpenNI2Driver::resolveDeviceURI(const string&) @ /tmp/binarydeb/ros-indigo-openni2-camera-0.2.6/src/openni2_driver.cpp @ 631 : Invalid device number 1, there are 0 devices connected.

It seems like it is trying to find a device (my camera), and never finds it. I also ran lsusb to see if my camera showed up, and what I got was this:

Bus 004 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 004: ID 192f:0916 Avago Technologies, Pte. 
Bus 003 Device 003: ID 046d:c31c Logitech, Inc. Keyboard K120
Bus 003 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I see no ASUS written as one of the bus drives (as suggested in http://answers.ros.org/question/19163... )

I have followed this procedure that was also suggested to me : http://robotica.unileon.es/mediawiki/... , but it also did not work.

Let me know if anyone has any tips on how to fix this with my ASUS Xtion. Thanks :)

EDIT 1: I did lsusb while i was ssh'ed into my jackal and my ASUS actually showed up on the list, so I am starting to think that I have to run the openni from my robot's computer, is that true?
