Hi

Is there any tool that is able to dump rosinstall with version tag from current workspace or .rosinstall file?

For example, I have following .rosinstall for my application, http://code.google.com/p/rtm-ros-robotics/source/browse/trunk/agentsystem_ros_tutorials/rtm-ros-robotics.rosinstall for developers to work against the trunk repositories. Then, Jenkins/Hudson server check the build status and add the latest tag.

I would be very happy if I can freeze this set as a .rosinstall file with version tag in all repositories so that I can commit the file to as a stable.rosinstall file and users always be able to setup with stable set of repository versions.

I have a program that takes string as an argument, such as

$ ./say "hello world"

and would like to invoke this program from roslaunch.

Here is an example of the launch file:

 < launch>
   < node name="say" pkg="say" type="say" args='\"hello world\"' />
 < /launch>

When I check the command line argument with

$ roslaunch say.launch --args /say

the output is

PYTHONPATH=/opt/ros/diamondback/ros/core/roslib/src /home/k-okada/ros/diamondback/say/say "hello world" __name:=say

and this is ok to me. but when I try to start this program from launch file by

$ roslaunch say.launch

the argument corrupts. It seems that the roslaunch divide string arugment into each words as written in the log file

[roslaunch][INFO] 2011-07-01 13:35:10,808: process[hoge-1]: args[[u'/home/k-okad
a/ros/diamondback/say/say', '"hello', 'world"', u'__name:=
say']]

Changing the launch file to

 < launch>
   < node name="say" pkg="say" type="say" args='\"hello\ world\"' />
 < /launch>

worked, but if there are other solution, I would like to know that.

@oridong thanks for the feedback. How can I re-produce your problem? Could you provide a bag file or source code to publ

HI, thanks for information, I have added new wiki for using valgrind on ROS. Any contributions are welcome. http://wiki.

We're maintaining our custom made ros client library ( http://wiki.ros.org/roseus ). We'd like to create new package that holds all messages files that compiled into eus language, so that uses do not need to generate on their local machine. How do I create such a packages or how do I tell ros build firm to do that.

As far as I understand, ros is the meta-package that contains several packages, https://github.com/ros/ros/blob/indig... , how do we not that which package does the ros contains?

is there way to get list of the depend package as we used rospack depend, for catkin?

UPDATE:

Original question is invalid, rospack depend should work.

you can use nodelet to load two edge detector into one process.

<launch>
  <node pkg="nodelet" type="nodelet" name="manager" args="manager"/>

  <node pkg="nodelet" type="nodelet" name="left_edge_detector"
        args="load edge_detection/edge_detection manager">
    <remap from="image" to="left/image_raw" />
    <param name="debug_view" value="false" />
  </node>
  <node pkg="nodelet" type="nodelet" name="right_edge_detector"
        args="load edge_detection/edge_detection manager">
    <remap from="image" to="right/image_raw" />
    <param name="debug_view" value="false" />
  </node> 

  <node pkg="image_view" type="image_view" name="left_edge_viewer">
    <remap from="image" to="left_edge_detector/image" />
  </node>
  <node pkg="image_view" type="image_view" name="right_edge_viewer">
    <remap from="image" to="right_edge_detector/image" />
  </node>
</launch>

I don’t know how to run the file contour_moments.cpp that’s able in this github link: https://github.com/ros-perception/vis...

I’m working with Indigo and I have installed OpenCV3 following this ROS.org link: http://wiki.ros.org/vision_opencv

when i run the command rosrun opencv_apps contour_moments it only appear a warning and nothing else:

[ WARN] [1450293289.992148166]: Topic 'image' has not been remapped! Typical command-line usage:
    $ rosrun image_rotate image_rotate image:=<image topic> [transport]

which topic should I use?? (I'm using a kinect, and it is working fine)

These nodes do not publish any message unless someone is reading that. so try roslaunch opencv_apps contour_moments.launch image:=image_raw and rostopic echo /contour_moments/moment

Hi,

I just follow the excellent ros_control tutorial at ( http://gazebosim.org/tutorials/?tut=r... ) and able to run robot in gazebo, that provide command interface for each joint

roslaunch rrbot_gazebo rrbot_world.launch
roslaunch rrbot_control rrbot_control.launch

Next, I'd like to control this robot from our application, so need to use JointTrajectoryAction (or FollowJointTrajectoryAction), so I added following code in rrbot_control

but I got have following error. Is it possible to run joint trajectory action while keeping ability to command value to each joint? I remember some real robto (pr2, baxter) has capable of this, so how do the archive that?

[ERROR] [WallTime: 1421039041.629407] [242.570000] Failed to start controllers: joint_state_controller, joint1_position_controller, joint2_position_controller, joint_trajectory_controller

can we choose package to be tested? currently catkin_make test tests all test code under src directory, but I'd like to check only specific packages, in order to save time.

I was wondering about how to publish cv:Mat. The tutorial wiki http://www.ros.org/wiki/cv_bridge/Tut... didn't give me an answer and following code seems working, but I suppose there are a way to do this without using old CvBridge interface.

        IplImage out_msg = sal_float_image;
        sensor_msgs::CvBridge bridge_;
        sensor_msgs::Image::Ptr saliency_msg = bridge_.cvToImgMsg(&out_msg, "passthrough");

        saliency_img_pub.publish(saliency_msg);
