I assume the beacon you refer to is an RF transmitter of some sort, in which case it is highly unlikely you'll find a technique that is accurate enough for guiding your robot. You'll need centimetre-level accuracy, which is really difficult using normal RF transmissions such as WiFi or Bluetooth.
The best method to get that accuracy is probably GPS RTK, but that assumes you have a clear view of the sky, which may not be true in your case.
The next-best is maybe UWB, see https://iosoft.blog/real-time-location-ultra-wideband/ or perhaps an optical method using fiducial markers, see https://iosoft.blog/raspberry-pi-positi ... cial-tags/
