ros_param_test

ROS package for experimenting with parameters in launch files

Summary

ROS has the ability to set parameters in a launch file that are in a global namespace, or in a local/node namespace. This allows the same parameter name to be used at different levels without collision.

Installing

It is assumed that you know how to work with ROS and install packages.

In short:

• Download the source tree to a folder named “ros_param_test” inside your ROS workspace directory
• Type “rosmake” at the command prompt
• Type “rospack profile” at the command prompt
