After the network is configured, ROS is automatically launched with a reasonable default configuration. The
ros-network-idprogram can then be used to display the network settings in a QR code that can be scanned by the handheld. Root permissions are currently required to extract the network password for wireless network. Once the QR code is scanned it can connect to the robot and connectivity can be tested using the chirp app. After that it is time for TurtleBots to roll out.
