do i need to build a base frame
in tutorial, there's a base frame called 'world', I wonder whether this base frame is defined by the system, or i need to build it in some way? i mean, if I want to define a transform from a base frame called 'base_frame', then do i need to build it by myself
You will have to be more specific, do you have a link to your tutorial ? Do you have an actual issue following this tutorial ?
