Any of the following three launch file scripts can be used to run local planner: Note: The scripts run the same planner but simulate different sensor/camera setups. #base_global_planner: "navfn/NavfnROS" #move_base. If UE4 and rosbridge are both running, then you should see the rosbridge node subscribe to two topics with the prefix /unreal_ros/.If you do NOT see this, then you likely have a problem with your pythom3.7 The diff_drive_controller allows for skid steer driving with the geometry_msgs/Twist command interface however it doesn't support direct skid commands.
