Move_base error: Local costmap doesn't work (robot unable to do obstacle avoidance)
Hi!
I am using Hydro on Ubuntu 12.04. I have tried the turtlebot_simulation tutorials and all went well. I am using Kobuki robot but I have changed the laser scanner input from the kinect to a laser. The laser seems to be correct as I can see the laser in RVIZ. However, when I launch move_base, the local costmap does not seem to be reading the laser and hence the robot fails to avoid obstacles that are not on the map. The global costmap shows correctly, but there is no local costmap. I am using 100% the same settings as in turtlebot_navigation package - the only difference is that I have a laser model instead of the Kinect.
I have tried the following reference, but it still does not work.

Any ideas? Thanks!
Are you able to visualize the local costmap in Rviz?
There is no local costmap in Rviz, only global costmap can been seen.
Change the local_costmap update_frequency parameter to 1.0 and try again.
