Hi
I'm looking for sensor that can detect one target in a room. I need to identify one marked specific target and get identification singe. Anyone have an idea?
Hi, I remember programming a LEGO mindstorm robot which had a infrared sensor and could find and approach a marker (small Ball packed with infrared LEDs) in a room.
I'm sure something like that ist also possible with the arduino.
The idea above sound good.
But what do you mean by "get identification singe."?

You could mark the target in some passive way e.g. colour (detect with a camera) or an active marker (an infrared led perhaps).
If you didn't want to mark it perhaps you could have a calibration stage where you scan the target with your sensor, record the results and then program your arduino to "look" (using the sensor) for an object which produces the same results (this might work for x-ray, temperature and ultrasonic sensors - although intensity decreasing with distance may be an issue).
You might also want some servos to help your sensor "look around".
