Re: [ros-users] actionlib tutorials

Hi Ben,

I'm sorry that you're having trouble learning how to use actionlib. I just
put together a fairly short example of how to use the simple action client
callbacks:
http://www.ros.org/wiki/actionlib_tutorials/Tutorials/Writing%20a%20Callback%20Based%20Simple%20Action%20Client

Hopefully this will give you something to build off of. If it doesn't
answer your questions, please let me know, and I can try iterating on the
example.

Good luck,
Vijay
