This python script is intended to ease the setup of the ros net. In particular, it will set the environment variables:

• ROS_IP
• ROS_MASTER_URI

install:

• python
• PyQt4/PyQt5

add in the end of your ~/.bashrc (as for ros setup files):

• source $HOME/.ros/rosnetSetup.bash

either:

• add this file in a ubuntu launcher, and run it or:
• run it directly as: python rosnetSetup.py

This script will spawn a GUI that will write the env variables in the file "$HOME/.ros/rosnetSetup.bash" If you source this file in your ~/.bashrc (see on top), your will configure the ros network.

it is composed of:

• network ip comboxbox
• ros_ip label
• checkbox whether or not you want to define ROS_MASTER_URI
• two edit boxes with: rosmaster_ip & rosmater_port
• apply button, to write configuration in the file "$HOME/.ros/rosnetSetup.bash"
• spawn roscore button, to spawn a terminal which execute a roscore command

the combobox gives you all the available ip of your networks. when you change it, it will automatically change the ros_ip label if you want another ip, select "other..." in the combobox and write your desired ip

• in rosmaster_ip editbox, your can write ips as "192.168.1.10", or hostnames as "myComputer", "localhost", etc.
• spawn roscore button will automatically apply the current settings before starting
