HI, I want to install the mit-ros-pkg on my ROS(following the tutorials: http://www.ros.org/wiki/mit-ros-pkg/KinectDemos/electric), however, in step 7, I always get the error like:

svn: URL 'https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk' doesn't exist Exception caught during install: Error processing 'motion_planning_common' : [motion_planning_common] Checkout of https://code.ros.org/svn/wg-ros-pkg/stacks/motion_planning_common/trunk version...etc.

I find that at the website of https://code.ros.org/svn/wg-ros-pkg/stacks, the motion_planning_common do not exist, maybe it has been removed, but how can I solve this problem?THX!

@davinci, silly number limiter! In the step "Validate certificate from MIT CSAIL's svn", in the terminal, it seems that I should enter the Client certificate filename(it shows like: Authentication realm: https://svn.csail.mit.edu:1443 Client certificate filename: ), so how to deal with it? THX!

@davinci, I was trying to use MIT-DEMO in GROOVY, so I didn't see the command "rosinstall ~/ros_workspace ~/ros_workspace/kinect_demos.rosinstall", now I changed my ROS back to electric and followed the tutorial(http : //www.ros.org/wiki/mit-ros-pkg/KinectDemos/electric), however, in the step

HI, I'm trying to use the demo packages created by MIT(http : //www.ros.org/wiki/mit-ros-pkg/KinectDemos), however, I don't know where to get the packages, I saw a address listed like: Version Control: https://svn.csail.mit.edu/mit-ros-pkg, should I use “svn co https://svn.csail.mit.edu/mit-ros-pkg” or "apt-get install https://svn.csail.mit.edu/mit-ros-pkg"?

2013-03-27 03:18:53 -0600 asked a question HOW TO USE OPENCV IN GROOVY?

Hi all, I'm learning how to use opencv in ROS, following the tutorial

http://www.ros.org/wiki/cv_bridge/Tutorials/UsingCvBridgeToConvertBetweenROSImagesAndOpenCVImages

However, in the example, I was confused about the several QUESTIONS:

In the example, there is just one cpp file, does it be used as two nodes(including the publisher as well as the subscriber)?

Following the tutorial,I was going to build the node, however, at the last step, something wrong happened:

/home/tishiba/practice_no1/src/practice_no1_1/src/cv.cpp: In constructor ‘ImageConverter::ImageConverter()’:
/home/tishiba/practice_no1/src/practice_no1_1/src/cv.cpp:23:32: error: expected primary-expression before ‘/’ token
/home/tishiba/practice_no1/src/practice_no1_1/src/cv.cpp:23:33: error: ‘camera’ was not declared in this scope
/home/tishiba/practice_no1/src/practice_no1_1/src/cv.cpp:23:40: error: ‘rgb’ was not declared in this scope
/home/tishiba/practice_no1/src/practice_no1_1/src/cv.cpp:23:44: error: ‘image_color’ was not declared in this scope
make[2]: *** [practice_no1_1/CMakeFiles/cv.dir/src/cv.cpp.o] Error 1
make[1]: *** [practice_no1_1/CMakeFiles/cv.dir/all] Error 2
make: *** [all] Error 2
Invoking "make" failed
![image description](http://)

I wonder if I didn't include all the header file in the cpp file, now in my cpp file ,I had include header files as followed:

include <ros/ros.h>
include <image_transport/image_transport.h>
include <cv_bridge/cv_bridge.h>
include <sensor_msgs/image_encodings.h>
include <opencv2/imgproc/imgproc.hpp>
include <opencv2/highgui/highgui.hpp>

..NOW WHAT SHOULD I DO? NEED HELP ! THX!
