I assume that it's possible run run Rviz on a machine other than the one running the robot. If so, how to I set the master address (the IP address of the robot) which Rviz should be subscribing to ?

Awesome. Setting ROS_IP and ROS_HOSTNAME on the remote computer fixed the problem. I notice that setting the 2D Pose Estimate using Rviz no longer works though.

You should only set one. ROS_IP and ROS_HOSTNAME are optional environment variable that sets the declared network address of a ROS Node or tool. The options are mutually exclusive

You need to set the ROS_MASTER_URI environment variable, see this page for details.

Does the robot need to have a web server installed on it (apache, etc) ?

you just need to be able to ping between the machines. you might also need to set the ROS_IP of the robot. Additionally you will need to sync the two machines or else you will have this problem: http://answers.ros.org/question/705/set-the-initial-pose-with-rviz

A can connect, but it seems that no data is being broadcast from the robot ("No messages received"). Is there anything I need to do with the parameter files to enable broadcasting of the map, for example?

can you rostopic echo the topics you want to see on the other computer?

Some of the problems about the "No messages received" are because you need to also set the ROS_IP and ROS_MASTER_URI inside the robot, that's because the robot (let's assume its network name is lil_robot) may receive the packets from lil_robot.local (where avahi might be able to send) but then send to lil_robot which will translate to localhost a.k.a. which is not the correct network name. so just by setting export ROS_MASTER_URI=http://lil_robot.local:11311 and export ROS_HOSTNAME=lil_robot.local inside the bashrc or zshrc after the source /opt/ros/version/setup.zsh the problem gets soved.

@fcolecumberri I have this issue with my turtlebot2, I can ssh to remote PC, but when I go into Rviz on remote PC, the 2D Pose Estimate doesnt work, I can see that I am publishing to the /initialpose on the terminal but the robot still does not move in Rviz. In the laptop physically connected to the turtlebot2, I have ROS_MASTER_URI and ROS_IP set to the IP of the robot. In the other Remote PC I have ROS_MASTER_URI set to the IP of the robot, and ROS_IP set to the IP of the remote PC. Did I do it wrong?
