Due to your answer I have undertood better. But Right now I have this problem. I can recive a topic value using rosbridge, but when I want send it by another topic something is wrong. I'll appreciate your support

var listener2 = new ROSLIB.Topic({ ros : rbServer, name : '/chatter', messageType : 'std_msgs/String' });

listener2.subscribe(function(message) { console.log('Received message on ' + listener2.name + ': ' + message.data); //listener.unsubscribe(); });

var jptopic = new ROSLIB.Topic({ ros : rbServer, name : '/chatter2', messageType : 'std_msgs/String' });

var str = new ROSLIB.Message({ data : 'message.data' });

jptopic.publish(str);
