Hokuyo UTM-30-LX-EW supports multi-echo mode.

Just randomly find out this and reminds me I asked a question here. Hope can help someone who is playing with cartographer and wondering the same thing. Below are the two ref links.

I know this is an old question, and I don't know which sensor produces MultiEchoLaserScan. But if you need, you can use standard LaserScan messages. Just change your .lua config file:

num_laser_scans = 1, num_multi_echo_laser_scans = 0,

After that just post LaserScan to "scan" topic. If your messages come from another topic name, remap in .launch file:

<remap from="scan" to="/my_laser_scan_topic" />
