Hi everyone, I'm new in this topic. I've installed SDK for my laser scanner, RPLidar to talk with ROS and Hector_SLAM, but... now I need to make a complete map like in this video: https://www.youtube.com/watch?v=Cfq3s... , but i can't get anything in rviz. I have connection with scanner because when i'm running view_rplidar.launch I can see some data. I can load some bagfile and see someone's map, according to this page: http://wiki.ros.org/hector_slam/Tutor...

I found this page, done everything like in instruction but still nothing: https://hackaday.io/project/7284-osca...

Only error from rviz is: No tf data. Actual error: Fixed Frame [map] does not exist

My mapping_default.launch file:

<arg name="base_frame" default="base_footprint"/>

<arg name="scan_topic" default="scan"/>
<arg name="map_size" default="2048"/>

I'm trying to deal with this for a week and I'm out of any ideas... Did anyone had this problem?
