footprint in rviz issue [closed]

edit

Hi,everyone,

How can the footprint be displayed in the rviz? In the old ROS version,there may be a local_costmap/robot_footprint topic published by move_base node. But in the indigo version there is no local_costmap/robot_footprint topic(all topic published by move_base is as below), so how can the footprint be displayed in the rviz?
