ROS Programming: Building Powerful Robots

Conventions used

There are a number of text conventions used throughout this learning path.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The *-ros-pkg is a community repository for developing high-level libraries easily. "

A block of code is set as follows:

…source /opt/ros/indigo/setup.bashsource /opt/ros/jade/setup.bashsource /opt/ros/kinetic/setup.bash…

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

<launch> 
  <node pkg="hokuyo_node" type="hokuyo_node" name="hokuyo_node"/> 
  <node pkg="rviz" type="rviz" name="rviz" 
  args="-d $(find chapter8_tutorials)/config/laser.rviz"/> ...
