Hi, this is a problem extended from my previous post. Are both Gmapping and amcl publishing Map to Odom TF? I described my objective and my system there.

After some more testing, we have found that there is no problem if we use our own global path, launch the navigation package without both gmapping and amcl. The tf from map to odom is published by a static tf. The robot can move along with the global path, can generate local cost map and local path.

The problem is when we launch fake_localization, there is no global plan and it gives a warning "Unable to get starting pose of robot, unable to create global plan". This warning is from move-base.

  //get the starting pose of the robot
    tf::Stamped<tf::Pose> global_pose;
    if(!planner_costmap_ros_->getRobotPose(global_pose)) {
      ROS_WARN("Unable to get starting pose of robot, unable to create global plan");
      return false;
    }

I have checked the TF, the related topics such as base_link_ground_truth, amcl_pose, all correct.

I cannot figure it out .. The only difference is that the fake_localization is updated at a only 1 Hz in frequency.

I think the most proper way to solve this problem is increase param transform_tolerance in amcl. Without change sourc

if you set "marking" to true in the global cost map, then the global planner should plan to avoid the obstacle as well.
