I'm interested in "ultrasonic range finder" type of sensors.
One that can return a rough raw value that can be converted into a distance
(from the sensor to an object in front of it) would be great.
By rotating it, and coupled with an angle sensor (or CM's tachometer) one
could do a "radar".
I'm trying to do a... well... *mechanical* "radar" using this kind of
rotation aprouch. I have to use a light flexible plastic with a touch
sensor in it's base.
This plastic "stick" detects any fixed or moving object by touching it, and
using the angle I can guess in what direction this object is (and how far
it is = length of the stick) Because it's *flexible* it doesn't get stuck
in the object it self.
...but, a "ultrasonic range finder" would be much better, of course.

| There is the classic Polaroid ultrasonic range finder. I think someone here was working on one of these or similar for lego? They work on the reflected signal approach. Now I thought you wanted to do off board triangulation. You can accomplish that (...) (25 years ago, 30-Nov-99, to lugnet.robotics)
