how can i change ros topic name?

[kimwin2]

Hi, I want to use 2 caemaras, which is same model(Asus Axion) The problem is that, their topic name is same so that it conflicts. My system is based on 1 ros master.

So, Can i change the topic name? Actually I tried to write "remap" on launch file.

<remap from ="camera/rgb/image_raw" to=""camera1/rgb/image_raw>

But other things(ir camera info, etc... ) remain yet.

Is there any way to change all of /camera -> /camera1 ?

thanks.
