(...) I'm not positive of that. If the US sensor is plugged in to a powered NXT, I can detect a clicking from it - I presume it's on. Regardless of what sensor I define the port as, this clicking continues. This is what I was basing my "can't turn (...) (20 years ago, 21-May-06, to lugnet.robotics)

Hello Brian, (...) That's easy to do in NBC, and not hard with NXT-G: to shut off the US sensor, just "use" another sensor type on the same port. Here is a sample program that switches the US sensor on/off with NXT enter button. (URL) If the sensor (...) (20 years ago, 21-May-06, to lugnet.robotics)

I've heard of one possible answer, though don't know if it is feasible on the NXT. If the robot software sends timed pings, regardless of time of flight, they will be returned with the same delay between them. So if you send two pings 73 msecs (...) (20 years ago, 21-May-06, to lugnet.robotics)

The problem here is the management of a single shared resource, i.e. the air through which the ultrasonic signals travel.
