TF error #21

Closed ZyHuang97 closed 2 years ago

ZyHuang97 commented 3 years ago

Thanks for your code. I tried to reimplement it, but the robot didn't move at all. It seems like a tf problem. Could you give me any advice?

Timed out waiting for transform from base_link to map to become available before running costmap, tf error: canTransform: target_frame map does not exist. canTransform: source_frame base_link does not exist.. canTransform returned after 98.075 timeout was 0.1.

Thanks and regards.

HI, @ZyHuang97. Thanks for interesting this package. Did you install map_server of ros?

aakashs0ni commented 3 years ago

Hi, @Geonhee-LEE. I have a similar issue. I have installed map_server. Furthermore, I have robot model error in Rviz. It says No transform from [base_link, body_link, lidar_link...] to [map].

@ZyHuang97 @aakashs0ni Hello, Did you install the robot_state_publisher also? Otherwise, let me know the detailed situation such as launch name, error logs, etc.

Hi @aakashs0ni where is the odom tf and odom topic? If you want to run, the odom tf and odom topic are necessary.

Hi, I am facing the same issue. How and where do you publish those topics from? Do I need to write a separate script for them?
