[ros-users] Interfacing ROS

Hello all,

So at first, i'm new to this list, so i'm try to be shortest as i can :) i have installed ROS and now ROS based on OpenQBO and i have some questions about in general ROS OS.
I found a lot of interface like camera and so on, and i would like to know how we can interface some "basics" motors or something like this with ROS ? Is there a quickstart / tutorial regarding first step with ROS ?

Thanks in advance,

Philippe
