laser frame Moving!!!

[PersianCoders]

hello Why does the laserscan move when I move the robot?

how can i solve this problem?

@PersianCoders This is something to do with ros2_control package. The odometry published by the package is not good. I would advise to use the default gazebo diff drive plugin which works smooth. ros2_control is not buggy for in-real-life application.

On which hardware are you running this? I remember i had a similar issue when trying to run the slam/Nav2 on the raspberry 4. It is not powerful enough, therefor I had to run the slam/nav2 on a separate pc.

i'm running it on my separate pc only. still I'm facing the same error

when i try SLAM mapping it is good and did not give any error. when I try to navigate. this error shows up

[Ishansehgal]

For me it is always there even when moving without any mapping.

orientation of lidar is wrong. correct rpy setings in lidar urdf.

[Vinothhk]

Thanks. I fixed the error by changing the chassis orientation such that it be the same as lidar orientation
