Making a ultrasonic sensor display a grid on the computer

Hi Guy's,

Just wondering if anyone knows if it's possible to make an ultrasonic sensor that can display a line representing objects in front of itself. The sensor would swivel on a slow moving servo.

I've never built a ultrasonic sensor, I have the parts on order and I'd like to know what I can do.

Possibly I'd need an encoder on the servo so there would be two reference points for the data.

Any ideas?

You mean kind of like this:

INTELLIGENT AUTONOMOUS VEHICLE WITH ULTRASOUND REMOTE SENSING

Yes thats pretty much the kind of thing I'm looking for, I'll try it with one rotating sensor and see if I get similar result. Thanks for the link
