I'm using navigation stack with a map created by hector mapping & hokuyo laser scan. I followed navigation's RobotSetup tutorial to set up my robot(pioneer P3AT) and was able to have it navigate to where I want within the known map.(I use rviz, and switch to 2D goal and just click on the known space) However, when I clicked on the unknow space, the arrow will show but the path cannot be built. I've tried the answer to the question of "how-to-set-unknown-pixel-as-goal-in-move_base" and it did not work for me. Any suggestions?
