Some titles I upvote without first following the link.

I'm conceptually with you, just watch out because there's become a real plague of things calling themselves "open source $foo" that are not. I don't mean this submission, I mean just in general there have been quite a lot

Wouldn’t it be kidnapped easily if it doesn’t use wires or GPS?

The sudden desire to add a small LLM and speech synthesizer so the mower can yell for help in a stranger danger scenario.

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.

Earlier quoted context omitted.

The wildlife (like hedgehogs) will feel very audited when they get sliced up by a razorblade, run over, and can barely drag themselves off your lawn to bleed out throughout hours of pain. If they don't bleed out, they often end up mutilated, unable to properly eat, walk, etc. Nice wildlife auditing. Hedgehogs are endangered in lots of areas of the world. Run your robot lawnmower during the day. If you don't like that…

Hedgehogs ignore loud moving things going their direction ?

No, but they curl up into a ball to protect themselves. Since they're spiky, that seems to work reasonably well against animals. Less so against blades.

So is this like Valetudo[0] but for mowers? Very cool! I wonder how much overlap / shared code there is between robot vacuums and robot mowers. [0]: https://valetudo.cloud/

Thanks for the link, this is super useful. I will probably use both valetudo and openmower soon! Is there anything comparable for security cameras?

"Let's be honest: 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 think we can do better!" The funny thing is: this actually works incredibly well. Perimeter wires are a PITA to install, but once that's done, they are a very practical and flawless method for making sure th…

I have a Mammotion Yuba and trust me, the grass looks awesome as a grid or in lines. It can even do logos. So far nicer looking grass and much faster then random.

I have a mix of older automowers (e.g. 315x) and newer bots like navimow x330.

The navimow does "mini stripes" and they do look nice, but the grass tends to look a little more "carpet" like with the automower randomized pattern.

How large is your lawn and is it mostly flat ? I want to try one for my lawn but I have very large lawn and one side is slopy/steep.

Here's what robotic mowers blades look like to understand how they work - https://images.squarespace-cdn.com/content/v1/676d76e61268a4... We just got a Sunseeker X7 to do ~4 acres of grassed area but probably ~2 acres will be garden beds and roads etc The hardware is there, it's all software now. People talk about updates and the robot improved amazingly, comments like - "these scuffs are from pre-update" These are E…

The price still needs to come down for what is effectively a slightly more rugged robot vaccuum. I could buy a used car for that, and have enough left over to make it run reliably. The quality of cheaper models is not great. I bought two from Einhell (power tool brand like DeWalt in Europe) and they both had to be returned due to motor failures. A replacement motor was €150 - for a €400 robot without battery (it uses…

The thing is, they are more than a robot vacuum. They need to be able to:

- deal with rougher, bumpier terrain (friction!)

- do so uphill through uncut grass

- not stall the mowing motor with high grass

- cover a larger area

- be waterproof against rain

All of these points need a lot more power individually, and especially so when taken together (and carrying the weight increase of all those upgrades). It seems reasonable they'd cost at least twice as much for "similar" feature/budget levels. And I think that's pretty much what we're seeing.

Please don't run them at night to protect animals like hedgehogs and others that are active at night.

I mean how fast do these mowers mow? I seriously doubt it's fast enough to run over an animal
