Probably a custom goal checker and/or controller that promises that it'll be properly aligned

Set the goal checker orientation tolerance to 2 pi. Then no matter what orientation its in once it achieves the XY toler

You could use a goal checker that doesn't care about orientation -- or just set it to 2 Pi so that when it reaches the X

Make the controller asymmetric in its behavior so it has no preference for forward or reverse. While in French, this is

Increase your queue size on the subscriber to ~10, 1 is probably why some get replaced in the queue

You should read it. Its considered the basic description of this technology which essentially all roboticists have read.

There is a goal tolerance in the goal checker, that stops there because that's within tolerances of the goal as set so t

Try cyclone. This is a relatively known issue in Fast DDS that persists today.

I can't speculate as to changes made if you've retuned DWB

I'm on the go right now so I can't get into all the details, but on_wait_for_result is exactly that method which obtains

You'll probably need to make something yourself that deals with the more exotic nature of your platform if you have that

We're discussing in a ticket in Nav2, closing question

You can really easily do that by adjusting the behavior tree to not have replanning or replan only on events that you ca

You're not seeing "fighting" because there is no feedback between them. The global planner sends things to the local pla

Sure, its always possible to convert a ROS 1 package to ROS 2.

I'm just going to be really honest that that issue can come up with really subtle issues with your robot's URDF configur

Hi

I'm trying to generate metrics for packages I maintain to see how many times they've been installed from ros buildfarm deployment system through apt-get/other package managers. Is there a way to find this info from repositories.ros.org or any other links? Anyone I can contact to get these metrics?

It remains marked in the master costmap as occupied, yes.

Yes, it remains until something tells it to be cleared either by raycasting or via an explicit costmap clear
