Hector Exploration Launch file

edit

Hi,

I am trying to launch hector exploration with my turtlebot with just an RPLidar A2 sensor. I am unsure what is required in the launch file to get hector exploration to work and also not sure what I should key in for the hector_exploration_planner node in the launch file (I keep getting this error ERROR: cannot launch node of type [hector_exploration_planner/hector_exploration_base_global_planner_plugin ]: can't locate node [hector_exploration_base_global_planner_plugin ] in package [hector_exploration_planner] ).

Any idea how to go about doing it? Any sample launch files that are available for viewing?

I am using the Hector Navigation stack from this link: https://github.com/tu-darmstadt-ros-p...

Thanks in advance!
