text: How to run Multiple Turtlebot 2/3 in real world?
  I have the latest ROS recommended distribution and Ubuntu 18.04.
  I have been able to run a single turtlebot 3 with no problem. Now how do I go about running more than one turtlebot using a SINGLE ROS MASTER on my laptop. Wether it is a turtlebot 2 or 3 does not matter. In the real world and not the simulation.
  I have read multiple answers on this site but do not understand how to fully implement it.
  I know the issue has to do with namespace and tf. How do I go about doing this? I need to distinguish between robot one and robot two. Please explain step by step as I'm new to ROS but I have done my reading and have a pretty good understanding of most things in ROS.
  Once implemented I will post all my results to help out everyone else.
