Hi everyone, I'm new in this topic. I've installed SDK for my laser scanner, RPLidar to talk with ROS and HectorSLAM, but... now I need to make a complete map like in this video: https://www.youtube.com/watch?v=Cfq3s4-H2S4 , but i can't get anything in rviz. I have connection with scanner because when i'm running viewrplidar.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/Tutorials/MappingUsingLoggedData

I found this page, done everything like in instruction but still nothing: https://hackaday.io/project/7284-oscar-omni-service-cooperative-assistant-robot/log/26164-first-foray-into-ros

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

My mapping_default.launch file:

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