I added my launch file. It looks like it contains all of them. I just copy-pasted from the tutorial, changed map location.

I don't even know how to change it. I tried your solution, it fixes "Global Status" but there still is RobotModel error: Screenshot

Hello,

I am trying to do this tutorial Writing A Global Path Planner As Plugin in ROS and i finally managed to get to last step, to simulate on Gazebo. After using roslaunch relaxed_astar test.launch and roslaunch turtlebot_rviz_launchers view_navigation.launch --screen Gazebo opens but I get an error :

Fixed frame [Map] does not exist

Any ideas?

Thank you.

Edit: My map files:

image: my_map.pgm
# a 584 X 526 map @ 0.100 m/cell
resolution: 0.1
origin: [-18, -15, 0.0]
occupied_thresh: 0.65
free_thresh: 0.196
negate: 0
