Due to fixes on stage (stage_ros) coordinate systems, poses of map and robots in .world files are wrong, and is not possible to set a goal because laser frames appears out of map. I have been working with multi-robot example and these are the lines that I fixed in willow-pr2-multi.world file (uncommented lines are the corrected positions):

#pose [ -26.300 29.200 0 90.000 ]
pose [ 29.200 26.300 0 0 ]

...

#pr2( pose [ -21.670 47.120 0 28.166 ] name "pr2_0" color "blue")
#pr2( pose [ -21.670 48.120 0 28.166 ] name "pr2_1" color "green")
#block( pose [ -24.269 48.001 0 180.000 ] color "red")

pr2( pose [ 47.120 21.670 0 28.166 ] name "pr2_0" color "blue")
pr2( pose [ 48.120 21.670 0 28.166 ] name "pr2_1" color "green")
block( pose [ 48.001 24.269 0 180.000 ] color "red")

I suposse that all .world files need to be fixed.

Thanks.

When i try to run the launch file: move_base_fake_localization_2.5cm.launch, there are 2 issues:

1. The map is not synchronized such as follow:
   
   I searched online that we should edit the origin of the map but I couldn't find out where to do so. Couldn't find a map.yaml file in the navigation repo too.

2. The stage window doesn't show up when I launch the file.

p/s: I'm using ROS kinetic and cloned the tutorial from indigo-devel.

Thanks.

request for new release on melodic , it requres #17.

Hello,

I am wondering, what does the following line mean in the simple navigation goals code?

goal.target_pose.pose.orientation = tf::createQuaternionMsgFromYaw(M_PI);

thank you,
Aaron

Hi,I have problem on running the roslaunch navigation_stage move_base_multi_robot.launch.
ros kinetic
the issuse is like this:
[ WARN] [1588174911.499353540, 5.100000000]: Timed out waiting for transform from robot_0/base_link to robot_0/map to become available before running costmap, tf error: canTransform: target_frame robot_0/map does not exist.. canTransform returned after 0.1 timeout was 0.1.
[ WARN] [1588174911.500381703, 5.100000000]: Timed out waiting for transform from robot_1/base_link to robot_1/map to become available before running costmap, tf error: canTransform: target_frame robot_1/map does not exist.. canTransform returned after 0.1 timeout was 0.1.

Hello, I want to know whether it can merge multi-robot's maps? Or just try to control different robots?

I'm pretty sure none of these build_depends are necessary:

• https://github.com/ros-planning/navigation_tutorials/blob/hydro-devel/roomba_stage/package.xml#L19-L22
• https://github.com/ros-planning/navigation_tutorials/blob/hydro-devel/navigation_stage/package.xml#L21-L26

in groovy, one can

rosrun stage stageros

in hydro, that is

rosrun stage_ros stageros

This breaks launch files which use stage.

Files in https://github.com/ros-planning/navigation_tutorials/tree/groovy-devel/navigation_stage/launch need to be updated.

Originally reported here: ros-planning/navigation#101

last release was Jan 2012. My commits since then (just fixing world files) have not surfaced. So the launch files in navigation_stage are broken with the last release, but fixed on groovy-devel.

@hershwg: maybe this is for you?

Dear navigation_tutorials friends,

As far as we know, the navigation stack requires a given goal in order to start a navigation. We were wondering if the stack allows robot automatically explore its surrounding and mapping. (such as greedy frontier exploration).

Since we are new on ros-planning/navigation pkgs, hope to hear your expertise on the issue.

Thanks,

When i launch the move_base_multi_robot launch fife, i receive this error
"The origin for the sensor at (9.74, 15.63, 0.15) is out of map bounds. So, the costmap cannot raytrace for it."
