I won't speculate too much on how sonar sensors will perform in the competition but I will say this: I personally have had sonar sensors "ring" each other and it caused a lot of issues. We had 4 sensors on the edges of a box and sensors that were facing away from each other could pick up the return from their opposite. So we ended up having the north sensor pick up signals from the south sensor.

If you call the sensor company they will tell you about this. The solution is to fire the sensors so they are staggered. We ended up firing them in a loop that passed ensured they were never firing at the same time to clear up the problem.

I suspect if every robot was using multiple sonar sensors and hammering them as fast as possible something might happen but I have no idea what the interference will be in a real-world scenario.
