Dear All,

I've created a simple catkin library including a class with a member function (lib_test). I want to use this class/library in another catkin pkg (caller_pkg). I receive this error :

CMakeFiles/main2.dir/src/main2.cpp.o: In function main': main2.cpp:(.text+0x23): undefined reference toUtility::dosomething(int)' collect2: error: ld returned 1 exit status caller_pkg/CMakeFiles/main2.dir/build.make:113: recipe for target '/home/alireza/catkin_ws/devel/lib/caller_pkg/main2' failed

The pkg contents are as follows.

* the library pkg <lib_test> *

 find_package(catkin REQUIRED COMPONENTS

Hello,

For Kuka youbot, I am trying to install (by source) its Hydro driver (youbot_driver) and ROS wrapper (youbot_driver_ros_interface) in ROS Kinetic. but I receive this error as follows.

ResourceNotFound: youbot_description

Dose anyone know how to solve this issue?

Hello All,

I need to edit the map that built by gmapping pkg. Is there any software that supports this format? almost all software open this format but they don't save changes under this format? Do you have any suggestion?

Dear All,

I am using the navigation pkg for Kuka youbot. My question is whether there is another way to set initial and goal poses of robot in the map except using 2D Pose Estimate" tool in rviz?

Thank you for your help and suggestions.

Hello All,

I need to use the ROS navigation stack for the environment with moving objects. Does anybody know if this stack handles such condition? If not, is there any package for this purpose?

Any suggestion is appreciated.

Hello,

There is tutorial for Sending Goals to the Navigation Stack in Ros wiki here. Is it possible to do the same thing for the initial position of the robot? if yes, how could I extract the actual pose of the robot first and then use it for this propose?

Thanks for helping me out?

Hello,

I have a Kuka youbot robot. The last updated version (by source) of the driver and ROS wrapper for this robot is Hydro. The most stable version of ROS is Kinetic. My question clearly is how I adapt the both hydro driver and ROS wrapper of this robot to Kinetic distribution? Is there any documentation for this purpose? I can not find any. Do I need to change CMakeLists.txt file? I would appreciate it if you help me out.

Sincerely,

@Geoff These are links to Youbot driver and its ROS wrapper. Thanks... git clone http://github.com/youbot/youbot_driver.
