I appreciate your help.
I want to generate tf statically so I use static_transform_publisher
Attached file is generated using view_frames and following code is launch
file to generate tf.
Thank you in advance your help.
//////
<launch>
<node pkg="tf" type="static_transform_publisher" name="link1_broadcaster"
args="0 0 0 0 0 0 base_footprint base_link 100" />
<node pkg="tf" type="static_transform_publisher" name="link2_broadcaster"
args="0 0 1.0 0 0 0 base_link base_laser 100" />
<node pkg="tf" type="static_transform_publisher" name="link3_broadcaster"
args="0 0 0 0 0 0 odom base_footprint 100" />
</launch>
