Hi all,<br>When i run the navigation using costmap2d, i see the laser scan in rviz, but do not see any inflated obstacles. <br>Rviz shows the grid cell messages are being published , and upon checking , /move_base/local_costmap/inflated_obstacles message is published with an empy cell array:<br>


<br>header: <br>  seq: 578<br>  stamp: <br>    secs: 1300546886<br>    nsecs: 279417959<br>  frame_id: odom<br>cell_width: 0.0500000007451<br>cell_height: 0.0500000007451<br>cells: []<br><br><br>Upon using rxconsole under ros.costmap2d debug mode i see this statement: Polygon lies outside map bounds, so we can&#39;t fill it. <br>


Since no path is planned, move_base enters clear/recovery mode.<br clear="all">Any suggestions?<br><font color="#888888">-- <br>Regards,<br>Hitesh Dhiman<br>Electrical Engineering<br>National University of Singapore<br>
