Hi all,I try to execute a standard navigation demo on PR2 using a map already built with gmapping and amcl.In short: if someone can point me to *working* launch files it would be perfect.****************In details, What I do:1) on the c1 machine of the PR2:roslaunch pr2_fcfm nav.launch------ nav.launch -----<launch><node name="robot_state_publisher" pkg="robot_state_publisher" type="state_publisher"/><node name="map_server" pkg="map_server" type="map_server" args="$(find pr2_fcfm)/maps/lptvMapCleaned.yaml"/><include file="$(find pr2_navigation_global)/amcl_node.xml" /><include file="$(find pr2_navigation_global)/move_base.xml" /></launch>----------------------------2) Then, on a remote machine, I launch rviz like that:roslaunch pr2_navigation_global rviz/rviz_move_base.launch*********But my problems are:A) the floor_scan in rviz display the /base_scan_throttled topic by default and I cannot see the white dots. If I replace it by /base_scan, I then can see the white dots but it sometimes rviz sporadically display a tf error because /base_scan cannot be transformed to /map. So it does not fully work... Any idea?B) If I set a pose estimation and then a goal in Rviz, I can see the computed displayed but the robot does not move. I tried to directly publish a move command:rostopic pub /navigation/cmd_vel geometry_msgs/Twist ...But the robot still does not move.And yes, the default move_base launch file seems to remap /cmd_vel to /navigation/cmd_velAny idea?
