I will try to provide more Information, because I think (probably I should say that I am almost sure) that I am missing something about the use of namespaces, and how to differentiate the instance of using the two kinects and my case:
My tf tree is the following:
And here is a visualization:
And those coordinate frames are referring to the following data:
So my question is how should I structure the launch file to make this work. So far I've removed some visual odometry related parts from the rtambap.launch file and now it is like this.
Near the middle part you can see the the relays I've added.
Now I am using this command to open up the nodes:
But I get this error:

And now it is not exactly clear to me how should I tackle this. Any ideas?
