How can I detect the position of a marker using tf library/package as a subscriber node and show on the terminal??
I want to detect the position of 10 marker using the tf package and the geometry_msgs.msg/PoseArray package and show on the terminal using rosrun command. It is a subscriber node. Publisher node is the 3D space. Just give me an example of a subscriber node as I'm very beginner in this . An detailed example of a python script will be appreciated with good explanation. Thanks.
