I tried running the plugin camera sensor from tutorial: http://gazebosim.org/wiki/Tutorials/1...

After launching rviz:

roslaunch rrbot_description rrbot_rviz.launch

I get (in gazebo terminal):

[gazebo-1] process has died [pid 6887, exit code 139, cmd /home/wojciech/catkin_ws/src/gazebo_ros_pkgs/gazebo_ros/scripts/gzserver /home/wojciech/catkin_ws/src/gazebo_ros_demos/rrbot_gazebo/worlds/rrbot.world __name:=gazebo __log:=/home/wojciech/.ros/log/dc769250-24b1-11e3-ae77-78e400c426ae/gazebo-1.log].
log file: /home/wojciech/.ros/log/dc769250-24b1-11e3-ae77-78e400c426ae/gazebo-1*.log

If anyone knows or has any ideas what's wrong, please feel free to suggest. Many thanks!

Hello,

I tried to complete this tutorial: gazebosim.org/wiki/Tutorials/1.9/Using_A_URDF_In_Gazebo

When I'm launching:

roslaunch rrbot_description rrbot_rviz.launch

I got this error:

  ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: robot_state_publisher
    ROS path [0]=/opt/ros/hydro/share/ros
    ROS path [1]=/home/wojciech/catkin_ws/src
    ROS path [2]=/opt/ros/hydro/share
    ROS path [3]=/opt/ros/hydro/stacks

Rviz launches but there is some worns and errors:

• FIXED FRAME: No tf data. Actual error: Fixed Frame [link1] does not exist

• No transform from [camera_link] to [link1]

• No transform from [link2] to [link1]
• ...

My configuration:

• ROS Hydro

• Ubuntu 13

I will be grateful for your help,

Wojciech

Could you try this? https://github.com/amor-ros-pkg/rosaria/issues/20

Hello,

I tried to build pointcloud_to_laserscan from turtlebor package, and I got this errors:

I have ROS-Hydro and Ubuntu 13.10 Thank you in advance.

Yes, but echo /scan is empty. I think the problem is, http://wiki.ros.org/depthimage_to_laserscan subscribes topics: /image & /camera_info, but openni_launch publishes msgs on /camera/rgb/camera_color & /camera/rgb/camera_info.

ROS - Hydro, Ubuntu 13.10

Yes, there is http://wiki.ros.org/depthimage_to_laserscan but it subscribes: /image & /camera_info, and openni_launch publish msgs on /camera/rgb/camera_color & /camera/rgb/camera_info. Is there simple way to change subscribed topics?

Hello,

I would like to navigate a Pioneer 3DX robot by Kinect sensor. It seems, that the simplest way to accomplish my goal is to convert PointCloud msgs to LaserScan msgs. I've launched 3dsensor.launch from turtlebot_bringup package to do the conversion. (ROS - Hydro, Ubuntu 13.10)

1) The problem is, 3dsensor.launch publishes no msgs on /scan topic.

2) What should I do next to accomplish navigation and get around obstacles?

Thank you in advance.

Hello,

I have compilation problem with Navigation Stack. I downloaded It from:

git clone https://github.com/ros-planning/navigation

and after running catkin_make I got errors:

[ 98%] Built target planner
/home/wojciech/catkin_ws/src/navigation/dwa_local_planner/src/dwa_planner.cpp: In constructor 'dwa_local_planner::DWAPlanner::DWAPlanner(std::string, base_local_planner::LocalPlannerUtil*:/home/wojciech/catkin_ws/src/navigation/dwa_local_planner/src/dwa_planner.cpp:150:45: error: 'class base_local_planner::LocalPlannerUtil' has no member named 'getGlobalFrame' make[2]: *** [navigation/dwa_local_planner/CMakeFiles/dwa_local_planner.dir/src/dwa_planner.cpp.o] Error 1 make[1]: *** [navigation/dwa_local_planner/CMakeFiles/dwa_local_planner.dir/all] Error 2 make: *** [all] Error 2

Can anybody help me please?

Thank you it worked after:

sudo apt-get install ros-hydro-openni*

Please close this question.

Anyone knows what's wrong? Kinect is not yet connected. I have Ubuntu 12.4 OS and ROS Hydro.
