Hi people,

I have a geometry_msgs/TransformedStamped() vector which I am trying to translate to sensor_msgs/PointCloud2. I have looked aroun in the rospy api docs but nothing clear comes out strking.

Question: Has anyone ever used rospy to do this sort of transformation in the past? Example codes/pointing to api references would be helpful.

Thanks!

Turns out that rospy_tutorials.Floats is a float32 object. In the subscriber code, ROS was downcasting the np.float64 be

Hi there,

I have a custom-built robot which I am trying to control with move_it. I have written the urdf and generated the srdf using the move_it setup assistant. All the topics from my URDF are being broadcast on tf links at 30Hz based on a sensor_msgs/JointState node I wrote. I am trying to link the base of my robot to the vicon /world coodinate frame (I am using the vicon_bridge package ). For some reason, I find that the frames being broadcast by vicon are crazily high (to the order of 200 - 400Hz) and as a result, move_it is not updating the tf transforms because of errors such as the following:

ERROR] [1477965797.682768512]: Transform error: Lookup would require extrapolation into the future. Requested time 1477965797.631547473 but the latest data is at time 1477965797.626859796, when looking up transform from frame [headnball_link] to frame [world]

My tf view_frames is given by the attachment in the link http://tinypic.com/r/23uwtmo/9 . Is there a way to specify the publish limit to a nodefrom within a roslaunch file?

Wifi or LAN.

Via USB? It's not possible AFAIK. What transport protocol would you use through a USB serial connection? You can certain

I have a code where I am checking for shutdown interrupt in a statement like so:

         int main()
          {
              bool  running(false);
              //running is set to true by a condition statement somewhere here
             for(; running || ros::ok() || !viewer->wasStopped() ;)
              {
               // ...             ...                          ...                  ...
               //do something
              }
          ros::shutdown();
          return 0;
       }

However, during runtime, when I do Ctrl + C, I get the usual warning ^C[ WARN] [1458383451.748234940]: Shutdown Signal Received. Shutting down ROS! but the node never shuts down.

Could I be missing something?

Try this: reinstall opencv3 while in the virtualenvs and specify the target install path to your virtualenvs opencv3 des

There are a couple of comments I have. First, you put your publisher within your callback function: void imageCa

Question is too ambiguous. Can you post the link to the repo you are using and explain what you have done what you would

Can you share the link where you found it?

You can test for shutdown using rospy.is_shutdown() method. The documentation reference is here.

Hi y'all,

I am trying to do face detection and position measurement with the Kinect for Windows v2 sensor. I have successfully calibrated the kinect camera and I need to port cob_people_perception over to my kinect v2 but while running catkin_make, I stumbled upon the following error:

-- +++ processing catkin package: 'cob_people_tracking_filter'
-- ==> add_subdirectory(cob_people_perception/cob_people_tracking_filter)
-- Using these message generators: gencpp;genlisp;genpy
CMake Error at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:75 (find_package):

  "cob_perception_msgs" with any of the following names:

  Add the installation prefix of "cob_perception_msgs" to CMAKE_PREFIX_PATH
  or set "cob_perception_msgs_DIR" to a directory containing one of the above
  files.  If "cob_perception_msgs" provides a separate development package or
  SDK, be sure it has been installed.

I'm wondering what I am missing?

I have removed the second ros-indigo-base install file and it's lesser in bytes. Thanks for your help though.

Hi everyone,

I have a ROS package which has been well-tested with Caffe and Tensorflow + Cuda. It is quite a burden explaining to users how to use this package and I feel it is best to ship it to users as a docker image. Now, on the docker hub, I see osrf/ros images for example, indigo as well as gazebo (which btw are dependencies for this project).

I have created the dockerfile as well as built the docker image but I find that the ros environment within the docker build is not active. I cannot catkin_init_workspace, catkin build nor catkin make. For the record, I pulled the OSRF/ros_indigo image in building my ros environment. There is no ros installation path in /opt/ros/... either.

The instructions are scarce and I wonder what I may be doing wrong.

Would appreciate your help.
