I haven't tried it yet, but there may be a way.

PCL can save to STL with savePolygonFileSTL which should be usable with RViz.

1. Works out of the box. But the goalhandles received in the GoalCallback on the server side have to be stored somewhere to get access to older goals. In my implementation I just store them in a vector.

2. Store the callback goalhandles on the server side and store the client goalhandles on the client side. Client goalhandles are the returned object of actionclient.sendGoal(goal).

3. Use the client goalhandle received from the sendGoal-Function.

4. The server goalhandle has a function allowing to access the goal. It can be accessed with (*server_goalhandle.getGoal()).[goal-attribute1]

Your tip with the folder worked. I didn't know, that the metapackages packages.xml and CMakeLists.txt have to be within a folder named like the metapackage. I also didn't find any documentation saying that.

I'm using hydro with catkin (v. 0.5.77) and I'm using a metapackage because I want to enhance a rosbuild-stack, which I catkinized. My problem is, that catkin_make recognizes my metapackage, but doesn't touch (in terms of compile) the package within the metapackage.

To show the problem, I created a metapackage called "metapackage" in catkins source directory (~/catkin_ws/src/metapackage) and a package "package1" in the directory of the metapackage (~/catkin_ws/src/metapackage/package1). The package "package1" is working fine and compiling, when I move it in catkins source directory. But if it's in the metapackages directory, it isn't touched by catkin.

I went through all the ros-answers questions and the wiki, but I didn't find another way telling catkin about my package except the run_depend-tag, which doesn't change anything.

Thanks in advance.

I just encountered the same problem and I just started teleop, because it was mentioned, that one should do that. [1] Maybe it should be mentioned on the wiki page, that one has to use roslaunch kobuki_keyop keyop.launch as teleoperation.
