no transform from base_footprint to map
Hey guys,
I've already read through several threads but none of them could help me, so I am trying it here.. I am setting up my turtlebot3 waffle_pi and simulating it with the tutorial https://emanual.robotis.com/docs/en/p... (I am at 11. 2.1.5) (I am using ros melodic with Ubuntu 18)
When launching "roslaunch turtlebot3_navigation turtlebot3_navigation.launch map_file:=$HOME/map.yaml" i get several warnings:
(1) [ WARN] : Request for map failed; trying again...
[ WARN] Timed out waiting for transform from base_footprint to map to become available before running costmap, tf error: canTransform: target_frame map does not exist.. canTransform returned after 0.1 timeout was 0.1. ...
(2) ...
I am asking for a solution for Warning (1) - (in rviz everything is launching but not at the right "place"...) For (2) there is an tutorials at ros which might help me. Anyway, I don't think this is the problem why my map is wrong... which is why I am trying to solve Warning (1)
Besides, I am a rookie in ros/ programming in general. Please tell me exactly what to do... Maybe I won't get it otherwise
rosrun tf view_frames: map->odom->base_footprint->base_link...
rosnode list: /amcl /gazebo /gazebo_gui /map_server /move_base /robot_state_publisher /rosout /rviz
Thank you for your help!
