drop move base launcher in yocs_navigator

[bit-pirate]

To properly support yocs_navigator/navigator.launch
we would need to add move_base and turtlebot dependencies, which would blow up this light-weight package.

if this launcher is used, then I suggest to move it to where it is used (what it is used with), e.g. turtlebot.

It was to reduce my headache to make internal launch convenient. I still think it is good to keep it here.

Instead, we can replace these params to free the turtlebot_dependency.

What is "internal launch"? If you are using this launcher inside larger launchers, e.g. for turtlebot, waiterbot, then please add move_base, velocity smoother etc. there.

Can you explain what benefits are there not to keep them in the package?
I kept them in the package for these reasons.

• don't want to keep the same launch files for every robot with small configuration changes.
• move_base and vel_smoother are used for all of our robots anyway.

It is possible to keep move_base and vel_smoother for every robot. But I kept them for these convenient reasons. Also I don't think it badly hurting dependencies since these modules are mostly required for all of our robots anyway.
