    Costmap2DROS::getRobotPose是通过tf变换实现的获取当前位姿。在这里有可能会出现tf的问题
    if (current_time.toSec() - global_pose.stamp_.toSec() > transform_tolerance_)
    
{
    
  ROS_WARN_THROTTLE(1.0,"Costmap2DROS transform timeout. Current time: %.4f, global_pose stamp: %.4f, tolerance: %.4f",current_time.toSec(),global_pose.stamp_.toSec(), transform_tolerance_);
    
  return false;
    
}

    同时应该检查时间是否同步，必要时可以尝试更换网络，譬如手机热点等
