Unbound Frontier_exploration [closed]

edit

Hello, I am curently working on a turtlebot with ubuntu 14.04 LTS and ROS Indigo, and i am trying to use send the frontier_server an actionlib goal to do unbound exploration. My problem is that when the explore_server receive my goal it say that "couldn't transform from map to U+0001 Failed to set region boundary" From the explore_server code it seems that the problem come from the updateBoundaryPolygon service, but i don't really know what the problem is.

Here is the code i use as actionlib single goal client

#include <ros/ros.h>
#include <actionlib/client/simple_action_client.h>
#include <actionlib/client/terminal_state.h>
#include <test_client/ExploreTaskAction.h>

int main (int argc, char **argv)
{
  ros::init(argc, argv, "frontier_exploration_client");

  // create the action client
  // true causes the client to spin its own thread
  actionlib::SimpleActionClient<test_client::ExploreTaskAction> ac("explore_server", true);

  ROS_INFO("Waiting for action server to start.");
  // wait for the action server to start
  ac.waitForServer(); //will wait for infinite time

  ROS_INFO("Action server started, sending goal.");
  // send a goal to the action
  test_client::ExploreTaskGoal goal;
  goal.explore_boundary.header.seq = 1;
  goal.explore_boundary.header.frame_id = 1;
  goal.explore_center.point.x = 1;
  goal.explore_center.point.y = 0;
  goal.explore_center.point.z = 0;
  ac.sendGoal(goal);

  //wait for the action to return
  bool finished_before_timeout = ac.waitForResult(ros::Duration(30.0));


  if (finished_before_timeout)
  {
    actionlib::SimpleClientGoalState state = ac.getState();
    ROS_INFO("Action finished: %s",state.toString().c_str());
  }
  else
    ROS_INFO("Action did not finish before the time out.");

  //exit
  return 0;
}

Any clues on where i made a mistake ?

EDIT : Ok, problem solved, the cause was the header that was badly configured : it need to be goal.explore_boundary.header.frame_id = "map" to work. The problem now is that the frontier explorer node only give goals that are at the robot's position, resulting in the robot staying at his initial position.
