tracking device

Forget it. you won't get sub 1m resolution to work reliably for a cheap toy.

Hmmm! Let me think. A tracking device with a 1 metre range? Got it!!!! Your eyes.

Doh!

Some people spoil all the fun.

I would imagine there are alternatives for short range communications, just not cheap from my point of view, not very easily to ued for tracing purpose. Well, if most you just thought it's not a real question but..., it just means I post it to a wrong place.

Keep asking if you do know, better than pretenting

Correct. But you wanted something cheap for use in a toy, and that's just not really possible. So your question was answered.

You posted to the right place, and you got an answer. If you want more options, give us more detail.

How about *you* tell us what is it is you are actually trying to do?

Dave.

Ultrasonic transducers can give you quite accurate range. They're cheap and can be easily interfaced.

Don't tell that to Maggie! She's in charge of my parent's home, and keeps it cat free. She even has a a sign that says: This house operated solely for the convenience of the DOG.

I need some newer pictures of her. She was very sick when these were taken. Her coat is much darker, now.
