Thank you.

 

Pretty cool video eh? I saw that you asked on the tube and am guessing that you have not yet received a response.

I watched it and figured - ok, an RF transmitter and the bot has a receiver and the capability to measure signal strength and a strategy to move and compare signal strengths (duh?)...and I first thought BLE.

So, I did a couple of searches - first this one
then I started to zero in on the RFID and went to this one

If you are looking for a paint-by-the-numbers project, sorry, I don't see one, but a good place to start is with this guy

and there is some suspicion see here

So, still no 7 part instructable, but a request for one here

So, I guess it is up to you to figure it out, build it, program it, and write it up.....you could call it a robot stalker

 

Thanks

 

I haven't watched the video, but just the still picture shows four antennas. So my guess is that it is doing fairly simple direction finding. You only need a pair of antennas, but then you have to physically turn in order to differentiate front from back. With four you can either work with two pairs that are orthogonal, or work with all four as a phased array.
