Telemetry system

Iziah

My idea is to use the Propeller as a short range triangulation system. I'm trying to get one chip to recognize another and give me a general direction it is in.

1: Detect another chip within 10 feet (radio, ultrasonic, or otherwise)
2: Use the cores to calculate signal strength

What other stepped do I need? How do I make the chips into transmitters or transceiver? Is there a thread or website that I might be able to use?

Trying to figure out how far away things are is a very common robot task. There are lots of different approaches to do this. I don't think any of the approaches I can think of use signal strength to calculate distance. There are just too many things that could influence signal strength of the various senors you list to use them as range finders (based on signal strength).

Some options would be to use a camera from Wii mote to see how far away three IR LEDs are.

There are other IR triangulation techniques as well.

You could use a laser range finder (Parallax sells one).

Ultrasound could also be use. Tracy Allen used ultrasound sensors to determine if people were within a room (I don't think he timed how long the sound took to travel though).

There are lots of different possiblities.

If you provide more information about what items you want to determine the range of and the kind of environment where this will take place, we might be able to point in a more specific direction.

In the mean time you will want to learn to program the Prop (if you don't already know how). Do you have a Propeller yet?
