It depends on what you mean by robotic mowers. If you mean motors that drive the wheels and you don’t have to walk behind them (or sit on them), yes, these exist without any cloud service. However, if you mean autonomous, then I don’t think those are here yet. The non-cloud robot mowers use human held remote controls.
I can think of one that is autonomous and doesn’t require the cloud for operation, but does require the cloud for the inital setup and mapping. Once it has the map loaded in, it doesn’t need an internet connection.

That pretty well describes 1st generation robo mowers: law roombas.
Thankfully they’ve evolved significantly since then and are on 4th generation tech now.

- Comment on Magnetic bass detection? 1 month ago:
If you just want the count and not the strength or waveform, I wonder if the magnetic field from the voice coil of the speaker would be strong enough to trigger a reed switch at that distance. A common reed switch has a top switching speed between 100Hz to 500Hz, which is within the 20Hz to 250Hz of human hearing bass.

- Comment on Turning an old Amazon Kindle into a eink development platform 6 months ago:
So, off to ebay I went! I saw a number of really cheap ones marked “BLOCKED BY AMAZON”; I decided not to go for these since theoretically they might have been stolen. In the end, I went for £7 Kindle 4 “non-touch”.
A few days later, it turned up. And I discovered why it might have been so cheap: its stuck in some sort of unquittable demo mode:
This makes me wonder the unit might have been stolen from a retail demo display.
Still, the content of the article is wonderful. I really like the author’s marriage of both the hardware and software aspects. I had no idea that an RS-232 interface was exposed off 3 soldier pads inside the unit. That certainly makes it a great place to start, but as the author shows a lot more knowledge (that the author had) was necessary.
A really interesting read!
