Hey all,

So, I screwed up pretty nicely in the
http://www.ros.org/wiki/navigation/Tutorials/RobotSetup tutorial and gave
example parameters that do not actually match those read by the code. I
imagine that this means many of you are using the default acceleration
limits for your robots rather than the ones you meant to set. If your
configuration for the base_local_planner includes the following spellings of
the acceleration limit parameters:

 acc_limit_th: my_x
 acc_limit_x: my_y
 acc_limit_y: my_th

They will be ignored by the code and you'll need to switch to:

 acc_lim_th: my_x
 acc_lim_x: my_y
 acc_lim_y: my_th

As specified here: http://www.ros.org/wiki/base_local_planner#Parameters

Again, I apologize for this and I've fixed the documentation. I'm also going
to take some time today to go through all the launch files I can find in our
repositories fixing this error. I'm pretty sure that I copied the wrong text
along with the rest of the world in at least a few places.

Truly sorry again... I just want to make sure that as many people as
possible hear about this mistake as possible.

Hope all is well and that this fixes at least one or two puzzling problems,
