Revision history [back]

Thanks for the pointers. Actually, I know and did all these tutorials. I wrote the following code

actionlib::SimpleActionClient<kobuki_msgs::autodockingaction> ac("AutoDockingAction", true); ac.waitForServer(); kobuki_msgs::AutoDockingActionGoal goal; 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.");

But I got a compilation problem in the line ac.sendGoal(goal);

In actionlib client tutorial, the same command above is used, but in my current example, did not want to compile. Is there any error in the code?
