When we run roslaunch turtlebot_bringup minimal.launch, and look at rosrun tf viewframes, we get many frames which includes "base_link". Now I am trying a new setup that does not include the turtlebot. I need "base_link" for a node called Laser_geometry otherwise I will have the following error:
"base_link" passed to lookupTransform argument target_frame does not exist.
ROS newb here, any help will be appreciated. Thank you
