To use ros, the following environment variables must contain those values:

  ROS_MASTER_URI    http://localhost:11311
  ROS_PACKAGE_PATH  /opt/openrobots/share
  PYTHONPATH        /opt/openrobots/lib/python3.14/site-packages
  PATH              /opt/openrobots/bin

As an alternative to the above configuration, commands can be executed by
using the `env.sh' wrapper. For instance, roscore can be started like so:
  /opt/openrobots/etc/ros/env.sh roscore

In Bourne shell scripts, the following file can be sourced instead:
  /opt/openrobots/etc/ros/setup.sh
