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.

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.
