the carrot planner could not find a valid plan for this goal [closed]

edit

hi, i am trying to use the carrot planner... but i always get the following error:

the carrot planner could not find a valid plan for this goal

even if i just wanna go 0.5m forward..there is nothing in the way or so. Here are my config files:

local_planner.yaml

move_base_node:TrajectoryPlannerROS:
y_vels: []
max_vel_x: 0.45
min_vel_x: 0.1
max_rotational_vel: 1.0
min_in_place_rotational_vel: 0.4
acc_lim_th: 3.2
acc_lim_x: 2.5
acc_lim_y: 2.5
holonomic_robot: true

global_costmap.yaml:

global_costmap:  global_frame: /map

robot_base_frame: base_link costmap/update_frequency: 0.2 costmap/static_map: false costmap/transform_tolerance: 1.0 costmap/footprint: [[-0.3, -0.3], [-0.3, 0.3], [0.3, 0.3], [0.3, -0.3]] observation_sources: laser_scan_sensor laser_scan_sensor: {sensor_frame: laser, data_type: LaserScan, topic: scan, marking: true, clearing: true, expected_update_rate: 0.5}

costmap.yaml:

global_frame: /map

robot_base_frame: base_link

costmap: update_frequency: 0.2 publish_frequency: 0.2 static_map: true transform_tolerance: 1.0 footprint: [[-0.3, -0.3], [-0.3, 0.3], [0.3, 0.3], [0.3, -0.3]] observation_sources: laser_scan_sensor

laser_scan_sensor: {sensor_frame: laser, data_type: LaserScan, topic: scan, marking: true, clearing: true, expected_update_rate: 0.5}

sorry i do not know how to use that code higliting right...i just managed it by the local_planner.yaml

do you have any ideas why the carrotPlanner isn't finding a path or do you know hos i should troubelshut to find the problem ?
