A few days ago I succeed mapping on my laptop

Now I trying to mapping as hector slam on raspberry pi3 (ubuntu mate)

By the way mapping not work on raspberry

I think the environment of raspberry is equal the environment of laptop

First my procedure is

  1. Downloading pakage about this project (Hector_Slam, ros_rplidar)

  2. building the files (catkin make) , setting a port

  3. modifying code of mapping_default.launch of hector_mapping file in hector slam.

I did not modify anything else    

The result of implementation is like this

a error not generate on terminal but also map not appear

what is problem??

For now I cab only be sure that /hecto_mapping is not publishing any topic with a map. But you hided the terminal with the information about the topics..
I think you should write parameters for the map size and resolution also..
