Hi everybody, I'm new on Erle System and ROS. I have 2 erle copter which has erle-brain-2. I want to see each copter has unique namespace. For example in two copters are published same topic which is /mavros/rc/in . But I want to see unique topic name, for example at copter1, copter1/mavros/rc/in and copter2, copter2/mavros/rc/in . How can i do this ? Sorry for my poor English.
