Try that : roslaunch freenect_launch freenect.launch

if it is not installed yet , run : sudo apt-get install ros-indigo-freenect-launch

Hi!

Openni_launch does not work anymore under Indigo for Kinect , but freenect_launch does. So install freenect_launch and libfreenect :

sudo apt-get install libfreenect-dev

sudo apt-get install ros-indigo-freenect-launch

Then call :

roslaunch freenect_launch freenect.launch

If it still does not work , disconnect Kinect from usb and plug again.

One more thing , it didn't work for me when Kinect was connected through an USB 2.0 hub but directly in USB 3.0 input of pc.

"This package contains launch files for using OpenNI-compliant devices in ROS. It supports the Asus Xtion, Xtion Pro, and multiple version of the Primesense 1.08 and 1.09 cameras. It does NOT support any versions of the Kinect. freenect_launch or openni_launch is the recommended package for using a Kinect with ROS."

I have been still struggling with the same issue.Any idea?

As Kamiccolo asked , I edited my question and added some more infos.

The modifications/adjustments in CmakeList.txt and package.xml do the generatin work. As i sad i do not think so that the problem is with message generation.Because catkin_make reports that message are created and it can also be seen by rosmsg. Thanks anyway.

Thank you for your quick reply. For catkin packages there are some adjustments/modifications that must be made under CMakeList.txt and package.xml. As you mentioned one of them is adding add_message_files( FILES ...) command.But in this form : add_message_files(FILES justMessageFileName1.msg)

Hi all,

I created a catkin package and defined a custom ros msg. I built it with catkin_make. Msg can be seen through rosmsg. But still my node can not import <package_name>.msg

ImportError: No module named blue_tracker.msg

That is the import command line : from blue_tracker.msg import *

Meanwhile there is no problem with ros package path.It can reach all other packages like roslib,rospy,smach..etc. I have alrady given two days to this annoying problem.All suggestions are wellcome.

Any ideas?

[more inforrmation as asked]

System:

         Bodhi 2.4.0 ,  Ros Hydro ,  Python  2.7.3

Ros Package :

         Catkin package "blue_tracker "  with a node trace_face.py

Code : (I blinded out all the parts of code but the ones give error to be able to focus on the problem)

 import roslib
 import roslib
 import rospy
 from sensor_msgs.msg import * # no problem with this line
 from blue_tracker.msg import * # here is the problem

 if __name__ == '__main__':
     rospy.init_node('track_face')
     print "test"



Error message :

Hi Warrior. Where did you save the beginner_tutorial package?

Hi Everyone,

For my project I need to write a package for face recognation in c++.I have so planned that in this package there will be a face_recog.cpp file and a AS_facerecog.cpp as Action Server which calls face_recog.cpp.And of course some other code and data files the FaceRecognizer module needs (like images , list of staff etc..).

Other packages will call this service from python codes.Here is my question:Do I need a boost wrapper or as in Pulisher/Subscriber structure, does roscore handel it ?
