Hi Scioni, I now tried to give inital pose for the Robot using nav_view. When I click in the map after clicking set Pose, then a crowd of Red Arrows appear at that place. Then I start moving the Robot but that crowd does not follow the way I move Robot. Also I try to send the goal but Robot itself does not move: I receive the same messages. How can I be sure that the Pose of the Robot is quite according to Map and how to set all these origins? Thanks in advance for the helps. regards -- View this message in context: http://ros-users.122217.n3.nabble.com/sensor-origin-tp1388170p1389284.html Sent from the ROS-Users mailing list archive at Nabble.com.
