Can someone please steer me in the right direction?

That's cheating - it's the robot that's supposed to steer.

Your problem isn't really one of telemetry (unless both you and your robot are equipped with GPS), but of knowing what the strength of the radio signal is.
Few cheap radio modules provide this information.

I think trying to home in on a RF signal is pretty much a non-starter as the needed antenna directionality and required precision of receive signal strength would not be cost or size efficient. IR or ultrasonic detection on a scanning head of the robot would probably be a more practical method.

I'm trying to make a robot that can keep up with a person who is running.  Will an IR Sensors/Ultrasonic sensors be able to do that?  Does that mean the person running should be carrying something that emits ultrasonic sounds?

This is a very difficult problem.
I don't think a microcontroller has sufficent "poke".

Exactly.  I apologize for not being so clear.  I would think RF Signals would be the way to go.  However, I have no idea how to go about using them.  Are there any books out there that can teach me?
