Multi-Robot tb3, one ROS Master
Hello, I am trying to connect multiple turtlebot3 burger to one master ROS on a different machine (portable pc). I tried to do the MASTER_URI and HOSTNAME solution, but the launch file of the turtlebot itself stopped working and was not accessible by the master. My final goal is to get the data of the sensors in a synchronized matter and give a command to the robots also in a simultaneous time. I tried to use Chrony with Terminator terminal broadcasting, but it is not the same thing, because each of the robots will be giving and getting data according to its own clock. Any Ideas?
Generally speaking ROS Master is the controller for multiple CPUs in a single robot. It should not be used to synchronize multiple robots.
