I am trying to use move_base for outdoor navigation without obstacle detection and without a map. How is this possible?

Using the setup below I get an error saying my starting position is not in the global costmap?


map_type: costmap
origin_z: 0.0
z_resolution: 1 # The z resolution of the map in meters/cell.
z_voxels: 2  # The number of voxels to in each vertical column, the height of the grid is z resolution * z voxels.

obstacle_range: 6 # The default maximum distance from the robot at which an obstacle will be inserted into the cost map in meters.
raytrace_range: 20 # The default range in meters at which to raytrace out obstacles from the map using sensor data

publish_voxel_map: true

footprint: [[1.162, 0.93], [-1.162, 0.93], [-1.162, -0.93], [1.162, -0.93]]
footprint_padding: 0.2
inflation_radius: 1.5  # controls how far away the zero cost point is from the obstacle
cost_scaling_factor: 0.8 # slope of the cost decay curve with respect to distance from the object. lower makes robot stay further from obstacles
footprint_clearing_enabled: true

# observation_sources: laser_scan_sensor

# laser_scan_sensor: {sensor_frame: laser, data_type: PointCloud2, topic: /cloud, marking: true, clearing: true, max_obstacle_height: 2, min_obstacle_height: 0.2}
