[ros-users] gmapping: Scan Matching Failed

[Ricardo Campos]

Hi,

I'm using gmapping to create maps. But, it returns a lot of messages saying "Scan Matching Failed, using odometry" and the resulting map has several overlapped maps.

I'm using these parameters values on LaserScan:

scan.angle_min = 0;
scan.angle_max = 3.14;
scan.angle_increment = 3.14 / num_readings;
scan.time_increment = (1 / laser_frequency) / (num_readings);
scan.range_min = 0.0;
scan.range_max = 80.0;

Someone can help me ?

Thanks
