Description
I am using Ubuntu14.04 and ROS Indigo to work on two turtlebots navigation. The way I configure the network is to run master_discovery_fkie and master_sync_fkie on each computer. Now I can see topics and services published from each computer.
Then I run roslaunch turtlebot_bringup minimal.launch and roslaunch turtlebot_navigation amcl_demo.launch map_file:=... on turtlebot01. The minimal.launch seems working but I am getting an error message when running amcl_demo:
[ WARN] [1549645522.472822603]: Timed out waiting for transform from base_footprint to turtlebot01/map to become available before running costmap, tf error: canTransform: target_frame turtlebot01/map does not exist.. canTransform returned after 0.100288 timeout was 0.1.
Here I paste minimal.launch, amcl_demo.launch and move_base.launch.xml
My minimal.launch:
