How to solve the Costmap2DROS transform timeout?
Hi everyone,
I have been following this tutorial and I was able to reproduce it until the last point: Navigating in the map. I did not modify any of the parameters provided by the tutorial and I am just trying to reproduce the screenshots.
However, when I try to navigate the robot in rviz with the 2D Nav Goal button, the robot does not move, and in the master terminal I keep getting the warning:
[ WARN] [1467770020.472781433]: Costmap2DROS transform timeout. Current time: 1467770020.4727, global_pose stamp: 1467770014.8758, tolerance: 0.3000
One more thing that I noticed is that if I run rosrun tf tf_monitor
I get that the publisher is unknown, instead of the robot_state_publisher:
Frame: wide_stereo_r_stereo_camera_optical_frame published by unknown_publisher Average Delay: -0.484559 Max Delay: 0
I suppose that the two problems are related, but I can't figure out a way to solve them. Do you have any idea how to fix this problem?
Thank you in advance for your help.
