Hey there, i got two laptops (A and B) (each connected to a robot). Using Laptop A as a master, i start all the nodes which are on Laptop B using ssh on Laptop A. So far so good. Since i have the same nodes on Laptop A as on Laptop B, i get a problem as soon as I start the nodes on Laptop A.

How can I distinguish between a node or a topic from laptop A and B?-->without renaming them.

Thanks
