Calling nodelet manager service from console

Question

Hey.

My question concerns how to use the nodelet manager service properly. Consider a nodelet manager has been started and is running. It's rosservice to load a nodelet (/manager/load_nodelet) is also available.

What do I have to call now to, let's say, start the openni_camera nodelet (openni_camera/driver) via this service.

rosservice call /manager/load_nodelet "/nodelet_name" "openni_camera/driver" [] [] [] "nodelet_name1"

tells my 'success' and /nodelet_name does appear under /manager/list topic for a couple of seconds, but vanishes after that with no debug message what so ever.

I am getting pretty frustrated over this, since the API has actually no documentation at all. (If you know different, PLEASE let me know about!)

Any suggestions? Would be deeply appreciated. Thanks.

Jasper

Answer 1

I wouldn't call the service manually from command line. That's what the nodelet script in the nodelet package is for. Have a look at the wiki page or execute

rosrun nodelet nodelet

for some information on using it.

If you really need/want to call the service directly from the command line, have a look at the source code of the nodelet binary (nodelet/src/nodelet.cpp).

Thanks for your answer. Yes, you are right. If I just wanted to control nodelets from command line I would go the way you stated. Since I intend something different I wanted to gain some more information. But thanks anyway. Looking into source code is the only solution then. Cheers

Answer 2

I am going now with another approach and just wanted to close this question. Now I am using app_manager to run the nodelet launch file remotely. This actually works quiet smooth and exactly as I need it. Cheers!
