local costmap empty in ros navigation
Hi everyone,
I have a Kinect on a mobile robot, where I use the package pointcloud_to_laserscan to publish a fake laser in the topic /scan for the navigation stack. The problem is that I am not able to see any obstacle in the local costmap. I have tried all the solutions, checking the maximum and minimum obstacle range, etc. When I do rostopic info /scan
, I see the following subscritions:
Subscribers:
* /rviz (http://192.168.1.25:46119/)
* /amcl (http://192.168.1.25:40276/)
Should I see any other node subscribed to this topic, like the move_base node? May be this the problem? I am quite lost, so any help would be really appreciated! The .yam configuration files about the navigation are just the same as described in the tutorial.
Thanks
Sure, if you want scan data in the costmap, the costmap should subscribe to scan. Please paste all your costmap configuration files.
