Are there some very basic tutorials/examples of how to use ROS somewhere?

I've worked through a bunch of the tutorials on the ROS site.  I made a turtle move around and did some graphing.  I still have no idea what I'm doing though.  Many of the examples I find don't work for some reason or another.  I think because they used an older version of ROS.  So is there a good example that walks through the whole set up for a robot?  I found some really good looking stuff on pirobot.org but I get about 2min into it before I get more errors.
