I am new to ROS trying to use teb_local_planning for motion planning of my differential car simulation. To learn this local planner, I am doing tutorials. However, i am facing an error in the second tutorial 'Configure and run Robot Navigation'. I followed the steps as stated in the tutorial but when I use .launch file by giving the command: roslaunch teb_local_planner_tutorials robot_diff_drive_in_stage.launch, a fatal error is coming:

[FATAL] [1505059392.954077796, 1.800000000]: Failed to create the global_planner/GlobalPlanner planner, are you sure it is properly registered and that the containing library is built? Exception: According to the loaded plugin descriptions the class global_planner/GlobalPlanner with base class type nav_core::BaseGlobalPlanner does not exist. Declared types are  navfn/NavfnROS

I am confused about this because in the tutorial there was no mention of global planner until now and so I have not made any modification regarding the global planner.

Please tell me what I am doing wrong and how to solve the issue.

I am using ROS kinetic on Ubuntu 16.04.
