My dad's solution was simple: "Mow the lawn!" directed at me.
That's why I moved out.

I made it for my country home and won’t be there for a bit but maybe one day I’ll document it. But the parts store I used closed down, Open Builds Part Store. It’s nothing proprietary to them, I just got all the v slot aluminum frame and connectors there to build the chassis. Then I got hub motor wheels on Amazon or Aliexpress and batteries too. Most small components I get on Amazon, motor controller. I went with off…
> after than it’s the same as building any vehicle LOL. Love this line ;-)
Granted I have built a few robots prior to this one as a hobby hacker, so this one felt pretty easy for me. If it’s your first, it will probably take you 6 months LOL. In almost all cases, you’re better off buying unless you just like the maker aspect of the project, which was true for me.

I'm assuming (perhaps unreasonably?) that given the suggestion you could run it at night, that it's silent, or near silent? If that's not the case, GP must be a madman.
I have an electric (though not robotic) lawn mower, and it turns out that it's not much quieter than a gas powered one. No engine noise obviously, but the blades spinning and hitting grass still makes a lot of noise (and indeed in my case it turned out to be the vast majority of the noise). So it wouldn't be a very good idea to run your robot lawn mower at night.
> The current generation of robotic lawn mowers sucks. Basically all of these bots drive in a random direction until they hit the border of the lawn, rotate for a randomized duration and repeat. I recently (a few weeks ago) bought one. While researching on the available options (which seemed relevant to me), actually almost none of the robots work this way. Most of them systematically go through the lawn. I think fro…

Wouldn’t it be kidnapped easily if it doesn’t use wires or GPS?
I often wonder about this. I think GPS is essential. Tie it to a location - if stolen, it won't operate. Then a way to text you if it is moved outside the designated area. Telling you where it is. At that point, I suppose it would still be worth stealing just for the battery? A hard problem to solve.

Must depend on the model. I can't hear mine from more than 10 meters away.
At night? I doubt that. At daylight with normal background noise level, possible.

The modern razor blade based robot mowers are barely audible. Segway claims 58 dBA, for context. Anywhere near a city (which, these smaller robot lawnmowers are really meant for smaller city lawns) is going to have close to that for background noise levels. Maybe it's partially audible if you're standing next to it, but with fencing and some distance between you and your neighbor, you aren't bothering anyone.
In a loud city where it doesn't matter anyway, yeah well, who cares.

This doesn't use GPS directly, as that would have insufficient accuracy. It uses RTK, which calculates relative position from a base station very accurately.
