Navigation problem: Rosbot2 does not move

I have made few changes to your move base configuration files:

Global costmap:

global_costmap:
  global_frame: map
  update_frequency: 0.5 
  publish_frequency: 1.5
  transform_tolerance: 1.0
  width: 16
  height: 16
  origin_x: -8
  origin_y: -8
  static_map: true
  rolling_window: true 
  inflation_radius: 0.0
  cost_scaling_factor: 10.0 
  resolution: 0.01

Parameter resolution defines the grid where planner should search for possible path. When it is set to 1, path will be aligned to 1 meter grid, this value should be definitely smaller.
Parameter rolling_window defines if costmap should follow robot. Otherwise it will be resized to map dimensions. Due to the fact that your map has resolution of 1 meter, costmap can not be resized to it or it will behave like resolution was set to 1.

Local costmap:

local_costmap:
  global_frame: map 
  update_frequency: 2.5 
  publish_frequency: 2.5 
  transform_tolerance: 1.0 
  static_map: false 
  rolling_window: true
  width: 3 
  height: 3
  origin_x: -1.5
  origin_y: -1.5
  resolution: 0.01
  inflation_radius: 0.0 
  cost_scaling_factor: 10.0

Costap with rolling_window enabled should have its center in robot position, thus origin is moved by -1.5 on both axes.

Trajectory planner:

TrajectoryPlannerROS:
 max_vel_x: 0.1
 min_vel_x: 0.05
 max_vel_theta: 2.5
 min_vel_theta: -2.5
 min_in_place_vel_theta: 0.5
 acc_lim_theta: 1.0
 acc_lim_x: 1.5
 acc_lim_Y: 1.5
 holonomic_robot: false
 meter_scoring: true
 xy_goal_tolerance: 0.5
 yaw_goal_tolerance: 0.5

 vx_samples: 6 
 vtheta_samples: 20
 controller_frequency: 0.5 

  
 occdist_scale:  0.01
 pdist_scale: 0.4
 gdist_scale: 0.2
 

 path_distance_bias: 0.4
 goal_distance_bias: 0.2

Parameter xy_goal_tolerance defines how far from destination planner should consider it as achieved. Distance is in meters.
Parameter yaw_goal_tolerance is analogous to xy_goal_tolerance but for angular position, unit is radian.
