Great read!

15 years ago, I had one of the first robot lawnmovers (Husqvarna) and did exactly the same thing: Watched it for hours, observing how it worked.

Back then, it seems it was programmed with instructions:

- Go! If you hit an edge, rotate in a random direction and ... Go! - If crossing the base-wire (a buried wire leading to the base station) while battery level < 40%, follow it and charge.
