Did you ever find an answer to this? I am having the same problem.

running dpkg -s ros-indigo-tf indicates that the package is not installed. How do I install it?

I am running the following launch file on my Raspberry Pi Indigo installation.

<?xml version="1.0"?>

<launch>
  <node pkg="xv_11_laser_driver" type="neato_laser_publisher" name="xv_11_node">
    <!--<param name="port" value="/dev/tty.usbserial-A9UXLBBR"/>-->
    <param name="port" value="/dev/ttyUSB0"/>
    <param name="firmware_version" value="2"/>
    <param name="frame_id" value="laser"/>
  </node>
  <node pkg="tf" type="static_transform_publisher" name="base_frame_2_laser" ar$

</launch>

But I am getting the following error

ERROR: cannot launch node of type [tf/static_transform_publisher]: tf

ROS path [0]=/opt/ros/indigo/share/ros

ROS path [1]=/opt/ros/indigo/share

ROS path [2]=/opt/ros/indigo/stacks

I have tried to build the tf package from source by cloning the git repository into "catkin_ws/src/tf" and running catkin_make from "~/catkin_ws" which is my workspace.

I am a ROS beginner and I'm having a lot of trouble getting this to work.

Thank you for you help

I figured it out. I was missing the "/launch/" in the path. Don't know why I didn't see it.

Also the two launch files hector_neator.launch and default_mapping.launch came from this project https://www.youtube.com/watch?v=jSlkj... (see comments section)

Thank you all for your help.

Never mind I fixed it. I just got rid of the include and copy and pasted default_mapping.launch into hector_neato.launch.

Hi all,

I am trying to run the following launch file: hector_neato.launch

<?xml version="1.0"?>
<launch>
  <node pkg="xv_11_laser_driver" type="neato_laser_publisher" name="xv_11_node">
    <!--<param name="port" value="/dev/tty.usbserial-A9UXLBBR"/>-->
    <param name="port" value="/dev/ttyUSB0"/>
    <param name="firmware_version" value="2"/>
    <param name="frame_id" value="laser"/>
  </node>
  <node pkg="tf" type="static_transform_publisher" name="base_frame_2_laser" args="0 0 0 0 0 0 /base_frame /laser 100"/> 
  <node pkg="rviz" type="rviz" name="rviz" args="-d rviz_cfg.rviz"/>
  <include file="default_mapping.launch"/> 
  <include file="$(find hector_geotiff)/launch/geotiff_mapper.launch"/>
</launch>

When I run it it gives me the following error

while processing default_mapping.launch: Invalid roslaunch XML syntax: [Errno 2] No such file or directory: u'default_mapping.launch' The traceback for the exception was written to the log file

This doesn't make sense because the file that it's complaining about is in the same directory as hector_neato.launch which is

/opt/ros/indigo/share/hector_slam_launch/launch

Please help.

Edit: Never mind I fixed it. I just got rid of the include and copy and pasted default_mapping.launch into hector_neato.launch.

I am using a neato XV-11 lidar and I am able to record a bag file. However when I run the launch file in this tutorial http://wiki.ros.org/hector_slam/Tutor... with my bag file I get the following error

[ INFO] [1455077561.968539391, 1454655528.267204049]: lookupTransform base_footprint to neato_laser timed out. Could not transform laser scan into base_frame.

Can anyone help?

I am trying to use the XV-11 to build a map using the hector mapping package here http://wiki.ros.org/hector_slam

I am able to do this tutorial http://wiki.ros.org/xv_11_laser_drive... to view the XV-11 data in rviz and I am able to do this tutorial http://wiki.ros.org/hector_slam/Tutor... to build a map with a recorded bag file.

What I would like to do is a build a map with my XV-11 in real time.

I have tried to run the XV-11 driver while at the same time running "roslaunch hector_slam_launch tutorial.launch" however I get an error in the laser scan " For frame [neato_laser]:Fixed Frame [map] does not exist "

Hi everyone I am very new to robotics and embedded systems. My goal is to build a small indoor ground robot that uses a Neato XV - 11 Lidar to build a map of its surroundings. I am using a Raspberry Pi 2 for interfacing the robot with the Lidar.

I am completely lost on where to start. I was able to find the following package for hector SLAM http://wiki.ros.org/hector_slam but I'm not too sure where to go from there. How do I install ROS on the Raspberry Pi 2? What version of ROS should I use and why? How do I send information from the Pi to my laptop? Do I need to install ROS on my laptop as well?

I just need some advice on how to start and where to look.

Thank you
