Hi ROS community, I run navigation stack (roscore,RosAria,Sicklms,move_base.launch). It every thing works. But while I send the goal, it sends and latches it but Robot does not move. The following Errors I get: [The origin of sensor at(-0.0, 0.02, 0.1(-0.0, 0.02, 0.15)5) is out of map bounds, so the costmap cannot rytrace it] [The Robot's start position is off the global costmap, Planning will always fail. Are you sure Robot has been properly localized. [Aborting because a valid plan could not be found. Even after executing all recovery behaviors.] [Costmap2DROS transform timeout;] The Map.yaml with me is as: image: map.pgm resolution: 0.050000 origin: [-100.000000, -100.000000, 0.000000] negate: 0 occupied_thresh: 0.65 free_thresh: 0.196 Any advice please? thanks and regards, safdar -- View this message in context: http://ros-users.122217.n3.nabble.com/sensor-origin-tp1388170p1388170.html Sent from the ROS-Users mailing list archive at Nabble.com.
