Hello everyone,

I am newbie in ROS environment and I have problem, I have a master node on my Raspberry Pi which is connected to the same local network. I communicate with RPI using SSH client like PuTTY or just in terminal in order to run ROS commands on it.

But I want to do the same thing using my own written application, I mean by clicking one button on GUI I want to establish ssh connection, login to system, set camera param, switch between different cameras, run cv_camera node on remote host and subscriber node on my local computer to display camera frames.

How to implement it? (I use Python and PyQt ) I thought about calling the shell script after clicking the button that would do all these tasks automatically. But maybe there is a simpler way to do it...

Just to clarify, when you say 'run ROS commands' do you mean launch and kill nodes?
