@Jordan Yeah you're right about the parameter. In-fact i had taken care of that earlier by changing the default value th

2019-12-05 05:11:35 -0500 marked best answer Path planned through unmapped region for goal present inside map.

could someone explain why sometines the global path planned by the robot for navigation ventures into the unmapped region? Images of the path planned to the goal are attached below. The planned path is in green. global path planned in unmapped region with goal point near by to robot's location

global path planned in unmapped region for a goal point far away from the robot

Through normal understanding, the global planner plans the shortest path in the mapped region and wouldn't traverse the unmapped region even if the goal point appears much closer through this.

Is there a way to correct this apart from editing the map?

Global planner : NavfnROS

Local planner : TrajectoryPlannerROS

OS: Ubuntu 14.04. ROS: Indigo.

Thank you.
