How to setup a navigation goal for a mobile robot
Hello ROS developers,
I would like to move my robot via terminal command 1 meter forwards and backwards. Afterwards I would like to rotate my robot in 360 degrees.
You can find my cpp code above:
#include "ros/ros.h"
#include <move_base/move_base.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, "nav_goal");
if (argc != 4 )
{
ROS_INFO("rosrun navigation nav_goal pos_x pos_y orien_z");
return 1;
}
//tell the action client that we want to spin a thread by default
MoveBaseClient ac("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 = "map";
goal.target_pose.header.stamp = ros::Time::now();
goal.target_pose.pose.position.x = atoll(argv[1]);
goal.target_pose.pose.position.y = atoll(argv[2]);
goal.target_pose.pose.position.z = 0.0;
goal.target_pose.pose.orientation.x=0.0;
goal.target_pose.pose.orientation.y=0.0;
goal.target_pose.pose.orientation.z = atoll(argv[3]);
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 successfully");
else
ROS_INFO("The base failed to move forward 1 meter for some reason");
return 0;
}
I would really appreciate your help! Thank you very much!
