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.
