Hi dear all,
During Path planning of Poineer P3-DX I bring up everything,
roscore,ROSARIA,sicklms,mapserver,amcl_diff.launch,move_base.launch and
rviz. Everything seems fine until I give the goal by pressing 2D Nav Goal
button in rviz. I give goal to move Robot one meter forward.It shows the
correct path to our goal on rviz avoiding obstacles. but after a while when
Robot starts moving on the goal it always moves backwards slowly and does
not stop. Somewhere stops for a nanosecond and then continues moving
backwards again,I switch it off for stopping. Can any one help to fix it ?
I use the tutorial http://www.ros.org/wiki/navigation/Tutorials/RobotSetup:
with following files:

move_base.launch:
<launch>
  <node pkg="move_base" type="move_base" respawn="false" name="move_base"
output="screen">
    <rosparam
file="/opt/ros/cturtle/stacks/ros_tutorials/poineer_zaman/costmap_common_params.yaml"
command="load" ns="global_costmap" />
    <rosparam
file="/opt/ros/cturtle/stacks/ros_tutorials/poineer_zaman/costmap_common_params.yaml"
command="load" ns="local_costmap" />
    <rosparam
file="/opt/ros/cturtle/stacks/ros_tutorials/poineer_zaman/local_costmap_params.yaml"
command="load" />
    <rosparam

    <rosparam

  </node>
