Hi all, I'm researching how to send object positions to robotics manipulation code like simple_arm_server.py. When reading
actionlib tutorial I was confused in simpleActionServer part(http://wiki.ros.org/actionlib_tutorials/Tutorials/SimpleActionServer(GoalCallbackMethod)), I noted that this server use subscribe mechanism to pass information from client(pls correct me if I'm wrong). Despite so, I know the formal was is using as_.acceptNewGoal() function. I don't where is the difference of them? Additionally, note that the client code(http://wiki.ros.org/actionlib_tutorials/Tutorials/SimpleActionClient) use the function "ac.sendGoal(goal)", the processing way of server is not a match?
