ok, so I should be using the obstacle topic published by rtabmap_ros/obstacles_detection nodelet to update my local costmap. Why can't I use the rtabmap/local_grid_obstacle topic? I don't really understand why my local costmap doesn't work with the rtabmap/local_grid_obstacle since I can see the topic publishing the obstacle point cloud in rviz. My observation source in the local_costmap_param.yaml should force move_base to subscribe to the rtabmap/local_grid_obstacle right? EDIT: move_base is now subscribing to  rtabmap/local_grid_obstacle and I can see it in rqt_graph however local costmap still does not get filled in with obstacles.

Clearly, I am missing some fundamental knowledge... maybe you know wht i need to know...
Thanks a lot for your help.
