Hi, If your simulation is constantly outputting data, you can reduce the throughput dropping messages using topic_tools

You can't use them simultaneously but can you use the Intel SDK without connecting to the camera?

Hi, Have you tried the same from a launch file? This doesn't work for me: Node(package='rviz2', executable='rviz2', nam

Dear Ros community,

After the last update in ros fuerte, move_base and map_server die after launch them with launch apps [1][2] that used to work properly.

They doesn't give much information, for instance:

[move_base-3] process has died [pid 10283, exit code -4, [...]

I tried to find a solution and I haven't found any.

This is the configuration of the system:

• Ubuntu 12.04 64bit
• ROS Fuerte
• ros-fuerte-navigation 1.8.3-s1367591379~precise

Has anybody found a similar problem? or have a clue of a possible problem/solution?

Thanks in advance,

see you saturday!

I am trying to create a geometry_msgs::Quaternion from two other (to create an Odometry message). I've found that tf::Quaternion is a btQuaternion but it is not a geometry_msgs one. I would like to know which is the difference and how can I work if I only have geometry_msgs::Quaternion inputs and outputs. Thanks!

I think I will be able to fix it tomorrow, anyway I gave an "up" to your question so you have +10 points :)

I meant this one (yours) which has the correct code

Great :) Please mark it as correct :) Thanks!

I am not using qt creator but roslaunch is XML

Have a look at https://github.com/ros-perception/perception_pcl/blob/indigo-devel/pcl_ros/include/pcl_ros/filters/passthrough.h#L63 it may help!

I think cloud_filtered should be pointer (not 100% sure though):

pcl::PCLPointCloud2::Ptr cloud_filtered

Hi,

Units are in SI, so the units in the Twist message are, as you say, m/s and rad/s.

You can have a look at REP 103:Standard Units of Measure and Coordinate Conventions

Have a look at move_base documentation and tutorials they will answer your questions.

by highly recommend I mean "JUST DO IT" @Rodolfo @yajaniaj

You should use Catkin to compile this package.

I highly recommend you to do at least the beginner tutorials :)

From your launch file, your static transform has wrong child and parent frame_ids, check out my example. (You don't need a frequency of 1000Hz either)
