My guy, robot mowers have been around for some time now. The catch is you need to bury a guide wire around the perimeter of the area the mower is meant to cut. Or at least that was the case the last time I looked into getting one.
There are some which are guided via gps now. However, i won’t trust them being so precise.
For me/us burying a guide wire was the better solution. Some manufacturers even claim, that you dont have to burry the line cos it will be overgrown by grass after a short amount of time.
GPS will only ever be accurate within 5 meters, which won’t cut it for small yards where even 1 meter over the line may send it down a hill or into the neighbors yard
Linus Tech Tips reviewed one that came with a little radio tower it used for position (guessing it used a combination of many sensors). Seemed to work OK in his flat little backyard.
Your WHAT?

GPS gets down to 1cm or finer precision with an additional, stationary receiver, and time corrections. https://learn.sparkfun.com/tutorials/how-to-build-a-diy-gnss-reference-station
People have built DIY mowers utilizing tech like this. Problem is, the RTK receivers are far too expensive for all but the higher end mowers.
