Map is not initialized, with Rviz and Gazebo simulation, ROS2
Hi. I have been following the Turtlebot3 tutorial with ROS2 Dashing (http://emanual.robotis.com/docs/en/pl...) which works fine for all the steps. Now, i want to try out simulation in gazebo and navigation2 with a simple robot i have built on my own. As a starter i have been using the turtlebot files, the only thing i have changed is the design of the robot (inside the model and urdf files). The sensors etc. is kept the same. I also use the map and world for turtlebot3. I want to perform the simulation part in the tutorial. First I run the command:
ros2 launch turtlebot3_gazebo turtlebot3_world.launch.py
which correctly visualize the robot and world in Gazebo. Then I run
ros2 launch turtlebot3_navigation2 navigation2.launch.py use_sim_time:=True map:=$HOME/map.yaml
RviZ opens with the correct map, but a lot of errors occur both in Rviz and in the terminalwindow:
When I used the turtlebot model, this errors also occurred, but they where removed when I set the initial pose for the robot. Now, when I try to set the initial pose, the command line tells that amcl has received an initial pose and set it:
But the errors in rviz are still there and the command window keeps printing the same errors as before.
The error in Rviz are Global Status: Error, Fixed Frame:Frame [map] does not exist.
I assume it is the transform between the map and gazebo/odom(?) which is missing, but I tought it would be fine when I set the initial pose for the robot. Does anyone have any suggestions to what could be the problem?
