Hi Nicolás,

I don't have an iRobot Create, but I have heard from one other ROS user 
that the wheel encoders are not necessarily very reliable.  Can other 
Create users comment on this?  In particular, I was wondering if the 
encoders are good enough to do SLAM using the ROS Navigation stack in 
case Nicolás is planning on giving that a try.
