Hello, in tutorial 4 (from nav2d Build a map with multiple robots simultaneously) is a paragraph that describes how to share the karto in and karto out to another roscore or robot. I'm using Ros kinetic and the ros-rt-wmp package doesn't want to compile in this Rosversion. So I'm a little clueless how to exchange the data from the topics. Is there for Ros kinetic a package which i can use? For clarification(what i'm using):

  • Ubuntu 16.04
  • Ros kinetic
  • 2x Turtlebot3 Burger
  • Seperate WIFI for the Turtlebots without another interference source

The mapping and navigation for one robot works without problems. Thanks in advance for your help.

Ps: Sorry for my bad english.

You said you are using the ros-rt-wmp package. With this it should be possible to share topics between robots (with separate ros-core's). So you can create a shared scan topic via ros-rt-wmp and use it to connect mappers on different robots.

Sorry I was meaning it doesn't compile so ros-rt-wmp doesn't working in my case.

In this case you would need some other means of sharing topics between systems. Or find out why ros-rt-wmp is not working. I previously used DDS together with a custom bridge node to share scans between mapper instances, but I can't really recommend this solution.

Maybe search/ask here at ros-aswers for what other possibilities exist to communicate between roscores.
