2011-10-07 02:37:53 -0500	commented question	Costmap's obstacle does not clear properly under sparse environment Ah, yes, the UTM-30LX is exactly the one we are using. So far so good even under direct sunlight. Can anyone shed some light to the way the costmap does the clearing?
2011-10-06 05:50:19 -0500	asked a question	Costmap's obstacle does not clear properly under sparse environment Hi, I would like to use Hokuyo to perform navigation under outdoor environment (open field for example). However, the obstacles detected before is not clearing out although the laser shows that there's no object. There is some hack that I can use for example http://answers.ros.org/question/1375/how-to-clear-older-costmap-just-before-updating but is there a more elegant way to do this? Perhaps through some parameter settings? Thanks in advance.
