Hello, I'm working on ROS kinetic on ubuntu 16.04.

I know path planner makes the most efficient path before the robot starts to get target goal.

I'm planning to apply machine learning to the navigation process with the AMCL localization.

But when I run the navigation stack,

the smart path planners (global planner and local planner) make the optimized path to the goal

with proper obstacle evasion, as far as I know.

What I want to do is to raise the accuracy and everything in navigation process with machine learning skills.

In this case, would it be a fatal error since the navigation stack nodes do whole the navigation process?

I'm going to subscribe to the global cost map and local cost map, and I'm afraid it is also necessary to launch the global and local planner nodes.

Anyone who is familiar with this kind of issue, would you please give help advice?

Thanks in advance :)

I cannot figure out what you're asking or proposing in this.

If you've replaced AMCL, global planner, and local planner with your own plugins, what's your concern?

I don't know why "raise the accuracy" or "fatal error" mean or refer to in this context.
