How to find out other robots finished goal? Hi, my goal is to send a goal on one node and find out the state of the goal

Multirobot_map_merge finish map Hi, i am working on the robot application using SLAM and I wonder if it is possible with

Thanks this was also very helpful.

This is great idea, but i suppose i would need to save the last position of the robot somewhere to use it later.

Realsense R200 for gmapping SLAM? Hello, i wonder if it is possible to use turtlebot's 3 Waffle 3D camera Realsense R200

It seems like the simple question, but is it possible to control robots with different ROS namespaces in one launch file programmaticaly? For example, i want to move robot1 one meter forward, and robot2 one meter backward programmaticaly in one file. Also i wonder if it is possible for a launch file which is launched for example in ROS_NAMESPACE=robot1, to programmaticaly control nodes of another robot in ROS_NAMESPACE=robot2? Thanks for answers.

Edit:

For example, i use code from this tutorial

What i want to know is, if it is somehow possible to write code like this:

#include <ros/ros.h>
#include <move_base_msgs/MoveBaseAction.h>
#include <actionlib/client/simple_action_client.h>

typedef actionlib::SimpleActionClient<move_base_msgs::MoveBaseAction> MoveBaseClient;

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

  //tell the action client that we want to spin a thread by default
  MoveBaseClient ac("tb3_0/move_base", true);

  //wait for the action server to come up 
  while(!ac.waitForServer(ros::Duration(5.0))){
    ROS_INFO("Waiting for the move_base action server to come up");
 }

 move_base_msgs::MoveBaseGoal goal;

 //we'll send a goal to the robot to move 1 meter forward
 goal.target_pose.header.frame_id = "tb3_0/base_link";
 goal.target_pose.header.stamp = ros::Time::now();

 goal.target_pose.pose.position.x = 1.0;
 goal.target_pose.pose.orientation.w = 1.0;

 ROS_INFO("Sending goal");
 ac.sendGoal(goal);

 ac.waitForResult();

 if(ac.getState() == actionlib::SimpleClientGoalState::SUCCEEDED)
    ROS_INFO("Hooray, the base moved 1 meter forward");
 else
    ROS_INFO("The base failed to move forward 1 meter for some reason");

return 0;
}

My goal would be to add two more move_base clients to control more robots from different namespace in this one source file.

---Edit---

I found out, this example is possible.
