hi Alexis,
I'm not sure what you mean by increasing the quality of the laser
scans. The scan data coming from stageros is as good as the
underlying simulation can provide. There's no noise added.
As for amcl, you can reduce its uncertainty by setting a pose, via the
'initialpose' topic. It's of type
geometry_msgs/PoseWithCovarianceStamped, which includes covariance
values. You cannot set the covariance independently of the pose,
however.
