Laser scan posting frequency
Is there a minimum frequency (i.e. samples per second or even seconds between samples) of laser scan data posts required to properly generate a ros bag file used to generate a successful map using gmapping?
That strongly depends on the speed of your robot. A drone requires a much higher rate than a wheelchair.
My setup is currently and differential base using a max speed 0.1 m/s, the laser scan rate is one scan every 4 seconds. - charlie
