sorry for the text links but I have not enough karma to publish them

2013-11-19 22:57:51 -0500 asked a question remap not work in a ros-pioneer3AT launch file

Hi, I've follow this guide(https ://docs.google.com/document/d/1C_GdAAQck-IT4H5GnsH3j6OezUbehUphtlnn8XU4XBk/edit#heading=h.5hhub0txkxyt) to configure my pioneer3AT with ROS Hydro. The code is here(https ://github.com/dawonn/ros-pioneer3at).

When launching the gmapping demo I have this roswtf output:

WARNING The following node subscriptions are unconnected:
 * /Pioneer3AT_rviz:
   * /Pioneer3AT_move_base/local_costmap/costmap_updates
   * /Pioneer3AT_move_base/NavfnROS/plan
   * /Pioneer3AT_move_base/global_costmap/costmap
   * /Pioneer3AT_move_base/global_costmap/costmap_updates

   * /Pioneer3AT/ps3joy/cmd_vel
 * /Pioneer3AT_gmapping:
   * /tf_static
   * /Pioneer3AT/laserscan
 * /Pioneer3AT_move_base:
   * /tf_static

I think that there are some <remap> problems, in particular in the file gmapping.launch:

<launch>
    <node pkg="gmapping" type="slam_gmapping" name="Pioneer3AT_gmapping" output="screen">   
      <rosparam file="$(find pioneer3at)/config/gmapping/gmapping.yaml" command="load" />

      <remap from="scan"          to="/Pioneer3AT/laserscan"/>
      <remap from="map"           to="/Pioneer3AT/map"/>
      <remap from="map_metadata"  to="/Pioneer3AT/map_metadata"/>
    </node>
</launch>

It is expected that the topic scan is remapped to the topic /Pioneer3AT/laserscan. If I echo the first I get the Hokuyo data but if I echo the second I get nothing! Why?

2013-11-18 21:40:13 -0500 answered a question laser drivers stack SICK LMS1xx stable?

Hi, the question may be old but I'm facing the same problem. I grabbed the lms1xx package at https://github.com/RCPRG-ros-pkg/RCPRG_laser_drivers The package is good for Hydro.

It works well.

The problem is still the lack of documentation. And the code seems good only for Ethernet connection, non serial.

2013-10-30 04:25:32 -0500 asked a question How to work with Pioneer 3AT in Hydro - Ubuntu 12.04?

Hi, can someone help me by describing a step-by-step guide to use the Pioner3AT robot with Hydro and Ubuntu 12.04? I would like to have it in Gazebo and to be able to move it with teleoperation.
