Finally I found the answer!

you can find hector_navigation here :

[https://github.com/tu-darmstadt-ros-pkg/hector_navigation]

after download it , make it:

rosmake  hector_navigation_master

after that you need a launch file

nav.launch:

<launch>

Hi, did you actually get results by running this package in this way? i installed and ran Hector_navigation and explorer nodes, but my robot just turns around itself (Z axis) without moving. whats your equipment? Thanks

Hi I also wish to work with Hector Navigation. Can you please explain how the motors are setup and how they interact with the navigation?

I know its been a very long time since you answered this question, but would you please provide a clearer little tutorial or update about how to run hector exploration? I would really appreciate your help here.
