I have this issue too
Since this issue is half a year old I don't exactly remember how to fix it.
But as I remember you have to go into line 79 in this file
https://github.com/Slamtec/rplidar_ros/blob/master/src/node.cpp
and replace max_distance
with a number greater than 0.
So just put in the 8 and it works.
After that you have to recompile your catkin_ws however you compiled it.
It took me like two days to figure this out... still no fix...
cheers, blusser
I could not get catorgapher to run, because publish_scan() sets scan_msg.range_max to zero. Output of
roslaunch rplidar_ros view_rplidar.launch
of line 315ROS_INFO("current scan mode: %s, sample rate: %d Khz, max_distance: %.1f m, scan frequency:%.1f Hz, ", current_scan_mode.scan_mode,(int)(1000/current_scan_mode.us_per_sample+0.5),max_distance, scan_frequency);
max_distance is always zero.
