Having taken the plunge and upgraded our trusty, boundary-wire-guided Flymo robot mower to a GPS-guided\u00a0Mammotion Yuka Mini 500<\/strong><\/a>, I thought I\u2019d share some first impressions.<\/p>\n\n\n\n

Scepticism, Satellites, and Software<\/strong><\/h2>\n\n\n\n

To be honest, I was a little sceptical about GPS-guided mowers. I\u2019ve used GPS in various ways for years, so I know both its strengths and its flaws. It\u2019s certainly good enough for navigating, tracking hikes or rides, recording my speed whilst windsurfing and even counting the number of waves I surf. It works well for finding Tupperware in the woods when geocaching too \u2014 but relying on it to stop a lawnmower wandering off, chewing up my flower beds or worse still, going for a swim in the pond? That\u2019s another matter.<\/p>\n\n\n\n

And it\u2019s not just GPS. The mower depends on software to interpret that GPS data and make decisions. And, well\u2026 all software has bugs. So I was a bit cautious, even if it did feel exciting. Call me a Luddite, but there\u2019s something reassuring about a physical wire in the ground.<\/p>\n\n\n\n

Installation and Charging<\/strong><\/h2>\n\n\n\n

Installation was surprisingly easy. No need to dig in a boundary wire \u2014 a big bonus. We removed the old charging station, snipped off the old guide wires, and said goodbye to Hector<\/strong>, our loyal mower of four years. Poor Hector!<\/p>\n\n\n\n

The new charging station slotted perfectly into the house we\u2019d built for Hector. We plugged it in, placed the new mower \u2014 now named Yuki<\/strong> \u2014 on the charger, and let him take his first full charge.<\/p>\n\n\n

Charging contacts were always a bit of a pain with Hector \u2014 small, fiddly, and prone to getting dirty. Yuki\u2019s contacts are much larger and more robust. They align easily with the dock, and are easier to clean.<\/p>\n\n\n

RTK Antenna Setup<\/strong><\/h2>\n\n\n\n

Next came installing the RTK (Real-Time Kinematic)<\/strong> antenna \u2014 the base station that feeds correction data to the mower for centimetre-level accuracy. It needs a clear view of the sky and ideally sits somewhere central in the mowing area.<\/p>\n\n\n\n

We didn\u2019t fancy drilling into the house, so we mounted it on the shed and powered it from inside. The mower supports multiple satellite systems \u2014 GPS, GLONASS, BeiDou, and Galileo \u2014 for improved accuracy and coverage.<\/p>\n\n\n

I\u2019m still not 100% sure how the antenna transmits its correction data to the mower (Wi-Fi? Bluetooth? Some other RF protocol?), but it works.<\/p>\n\n\n\n

Mapping and Connection<\/strong><\/h2>\n\n\n\n

After downloading the Mammotion App it was time to pair both the RTK antenna and the mower to the app. This was easy to do by following the prompts. The connection was made via Bluetooth, and from there, we connected them to our Wi-Fi network as well. There is also a built-in 4G SIM card that is used for remote communications with the mower when there is no wi-fi available (which might be the case at the bottom of the garden). The 4G communications needed no set-up, they were just working out of the box, but the 4G capabilities are only free for 6 months, after that there is a \u00a349 annual charge for the service. It\u2019s not essential as it\u2019s only used for remote communications (more on that later) and if WiFi is available, you can use that for free instead.<\/p>\n\n\n\n

With everything connected, we had to teach Yuki the layout of the garden. There\u2019s an automatic mapping feature using the built-in AI camera, but the manual recommends against it for complex gardens or those with ponds (tick and tick), so we opted for manual mapping<\/strong>.<\/p>\n\n\n\n

You guide the mower using app controls \u2014 forwards, backwards, left and right. It was responsive and surprisingly easy. In no time we\u2019d traced the perimeter and set the boundaries.<\/p>\n\n\n\n

Tasks and Zones<\/strong><\/h2>\n\n\n\n

We mapped the whole garden as a single area \u2014 just 174m\u00b2, apparently! In hindsight, we should have divided it into two or three zones. That would allow us to set custom mowing schedules (e.g., skip the soggy bottom corner when it\u2019s wet). We might revisit that later, once we\u2019ve fine-tuned the mapping.<\/p>\n\n\n\n

When setting up tasks, there are various parameters you can set.<\/p>\n\n\n\n
