A simple script to automate the ROS ip in .bashrc on linux

IPsetup is a collection of scripts useful when preparing to connect to ROS robots (only tested on turtlebot 3, but should work for most ROS robots)

INSTRUCTIONS

1. Open .bashrc in your home directory (might be hidden, CTRL+H to show/hide hidden files)

2. Look for

   a. export ROS_MASTER_URI=http://"SomeIpAddress":11311

   b. export ROS_HOSTNAME="SomeIpAddress

   ("SomeIpAddress" can be your ip or some other ip address)

3. If you found the lines in step 2 replace them with:

   a. export ROS_MASTER_URI=http://HOST_IP:11311

   b. export ROS_HOSTNAME=HOST_IP

   If not add the lines at the bottom of your .bashrc

4. Run init.bash <./init.bash> in terminal (without <>)

5. Run ros_ip_setup.bash <./ros_ip_setup.bash>

unity_ros_ip_setup.bash

There is also a file called unity_ros_ip_setup.bash.

This file does the same as the ros_ip_setup.bash file, with the added functionality of also getting the wsl host (windows) ip.

After getting the ips it proceeds to also update the ip field in a specific launch file regarding the ip of the robot.

That last part might not be correct atm, but I have yet to test this while connected to a robot, so if it specifically needs the robot ip you might need to remove that part of the process, and manually set the robot ip
