So I am trying to map a model(urdf) to my hector slam project which seems to have base_frame. I don't have any base_link?
rosrun tf tf_echo /map /base_link
CFailure at 1485981006.541937303 Exception thrown:"base_link" passed to lookupTransform argument source_frame does not exist. The current list of frames is: Frame laser exists with parent base_frame. Frame base_frame exists with parent map. Frame scanmatcher_frame exists with parent map.
If I change my URDF from base_link to base_frame, I have less errors in RVIZ but the wheels are not connected to the robot?
