These packages are basically the same, ua_erratic_player is slightly
modified to work with our own model of erratic mobile base (can be found in
erratic_description package). We are publishing a single transform from
"odom" frame to "base_footprint" frame, instead of 3 transforms that
erratic_player publishes
("odom"->"base_link_offset"->"base_link"->"base_laser_link"). I've also
modified the code so that you can specify topics for odometry and battery
information in launch files, but these can be removed since we can just use
ROS remapping mechanism. Other than that they are the same.
So if you'd like to use our model, I'd suggest also using our modified
player driver.

Here is the link to erratic_player source:

Thank you very much for adding documentation! There's absolutely no problem
with people contributing docs :)
