Newbie here! Not sure what the protocol is for newbies to this forum so apologies in advance if I make mistakes.
I have been interested in learning ROS for a while now and have been on the hunt for  good resources to learn with and  an inexpensive ROS compatible robot to learn on. Recently, I discovered Bernardo’s (@brjapon) great book “Hands-On ROS for Robotics Programming” and thereby found both a great resource and a great educational robot!
This means I am pretty late to the handsonros party for this forum based on the excellent posts I have seen here in this area (lookin’ at you @KeithW, @cyclicalobsessive, @jimrh, @pitosalas, @cleoqc and probably others I haven’t found yet).
So, I will be slowly following the book, starting with Dexter OS (depreciated, I know but hey, I did say I was following the book…) with a detour to the GoPiGo OS (not in the book of course but it is the current official Modular Robotics OS for GoPiGo) and then on to ROS (1 for now, 2 for later) and see where it leads.
I hope there are some other newbies on this path that I can compare notes (and maybe commiserate) with, and, for the old hands, I hope I can learn from you when I get stuck!
