Take a few moments to familiarize yourself with those pages since we'll be
making use of them during the rest of the tutorial. One important item to note
-is the "Elapsed event time" value, which displays how much time has elapsed
-since the robots have reached their initial positions. The elapsed time is
-also connected to when "$ns at" events in the NS file are run. In
-this case, there were no events in the NS file, so we'll be moving the robot by
-sending dynamic SETDEST events, much like sending START and STOP events to traffic generators and "$ns at" events in the
+NS file are run. In this case, there were no events in the NS file, so we'll
+be moving the robot by sending dynamic SETDEST events, much like sending START
+and STOP events to traffic
+generators and program
objects.
