Revision history [back]

It is not necessary if you are not using rosbag to play back sensor data.

My setup is:

a real robot P3DX
a laser
a cellphone running Android APP to teleop robot

I didn't set the param 'use_sim_time'. I just ran gmapping and teleop robot to build the map, and then used map_saver to get the map and .yaml file.
