It is enjoyable to observe how rapidly issues are bettering in residence robotics proper now. Sunseeker’s new X5 robo-mower is not excellent, nevertheless it does a formidable job with advanced, multi-zone lawns due to its RTK-GNSS positioning system.
Earlier than about 2019, for those who wished a robotic to mow your lawns, you wanted to root round within the dust putting in boundary wires – a process that might get fairly onerous with a decent-sized yard. Most fashions bounced round in random instructions, leaving rakish tufts of lengthy grass poking up in locations the place likelihood hadn’t pointed the mower but.
However we’re now within the age of AI imaginative and prescient and machine studying, to not point out high-precision real-time kinematic (RTK) satellite tv for pc positioning. Boundary wires are relics of a bygone age, and robo-mowers at the moment are able to mapping out lawns and tending to them so systematically that they are taking among the juiciest jobs within the lawn-mowing recreation – like manicuring the hallowed fairways of PGA tour golf courses.
RTK positioning was first launched to robo-mowers with Husqvarna’s EPOS series in 2020. Common consumer-grade GPS units just like the one in your smartphone can solely inform you a location inside an error radius of about 16 toes (4.9 m) – nowhere close to ok for a mower.

With RTK, you arrange a base station someplace shut by, after which the bottom station and the roaming robotic can examine the section variations within the radio indicators they’re getting from varied GPS satellites, do some advanced math and wind up with an accuracy of extra like an inch (2.5 cm). Now we’re speaking.
The Sunseeker X5 combines RTK positioning with video-based SLAM (simultaneous localization and mapping) from a stereo digicam array you possibly can see peeking up from the sloping “hood” of the sporty-looking robotic chassis, as if WALL-E’s head was additionally a scorching rod’s supercharger.
Which means you possibly can plonk it down in a “work zone” and let it go to city determining the place the boundaries of the garden are by itself – or else you possibly can interact a clumsy, laggy distant management mode through Bluetooth out of your telephone and easily drive it across the edges. You can too nominate “corridors” of non-lawn space like paths and concrete and whatnot, which the robotic can use to journey between work zones.

So, with the RTK base station antenna arrange on the crumbling roof of my again yard automobile port, I confirmed the robotic round our break up again garden, then took it up the aspect path, via the gate and round to map out the 2 areas of our entrance garden. Feeling sporty, I then confirmed it find out how to get out the entrance gate and over to the character strip (which is the strip of grass between the sidewalk and the road for these outdoors Australia).
Then, I personalized the 5 zones it had mapped out, selecting a neat and environment friendly route for the robotic to stripe every garden in, and let the little Sunseeker get to work. Absent the random Roomba-style bouncing round we witnessed with, for instance, final yr’s Worx Landroid Vision, it cruised via the 220-sq-m (2,370-sq-ft) of these 5 work zones in about an hour and 20 minutes, then sauntered again within the entrance gate, down the aspect path, via the aspect gate, and again to its little charging station within the again yard.
A non-RTK outfitted machine would’ve needed to be hand-delivered to the entrance yard and nature strip. This can be a terrific step ahead.

As Sunseeker’s second-biggest mower, the X5 is designed to deal with lawns 10 occasions the dimensions of ours, with as many as eight separate zones. That is per map – you possibly can completely drag this machine all the way down to the vacation home, make an additional map for that and have it preserve issues tidy for you there, too – supplied you are prepared to maneuver that RTK base station, then put it again precisely the place it was whenever you return residence.
The place it dares to go, the work it does is excellent; with slightly common consideration, the grass appears superb. This mower is exceptionally quiet, it will probably deal with a reasonably first rate slope as much as about 30°, and you may alter the peak of its 8.6-inch (22-cm) diameter razor-bladed reducing disc for garden heights between 1.6 to three.2 inches (4 to eight cm).
I say the place it dares, as a result of … effectively, there are particular areas the place it dares not. One nook of an in any other case unobstructed little bit of again garden stays an absolute no-go zone, although I put it in distant management mode and confirmed it proper to the perimeters.

Different bits of the yard the place issues get advanced appear to confuse it too, like the steps to the children’ cubby home above, which have curiously spawned a good sized L-shape of unmown grass off to the aspect. And regardless of a “journey on border” function that is presupposed to “guarantee each edge is trimmed cleanly, leaving no uncut grass behind,” among the edges clearly don’t get sufficient love, together with probably the most annoying little bit of grass on our block, which runs up alongside a fence out on the character strip and someway grows 3 times faster than the rest.
Manually re-mapping every space out utilizing distant management solves a few of these points, however the X5 actually does not appear to love working near fences. That could be a clever selection at this stage; in lower than a month of motion, the X5 has managed to scratch up its sports-car bodywork on either side rubbing towards branches, bricks and partitions.
By way of errors and the like, the Sunseeker X5 is comparatively autonomous in comparison with earlier machines I’ve tried out, and barely will get irredeemably confused or caught, or wants help. That stated, it did handle to get bogged in some free dust at one level, and one other time, it misjudged the sting of our nature strip and beached itself falling off the curb. However generally I have not needed to carry it round or rescue it a lot in any respect.

The app is fairly painless to make use of – though I’ve to say I am a bit puzzled by the automated advisable mowing schedule, which allocates not more than quarter-hour a day. Irrespective of; that is straightforward sufficient to tweak to your liking.
The Sunseeker X5 is at the moment retailing for US$2,199. That is on the expensive aspect for an RTK/vision-enabled, half-acre (0.2-ha), Chinese language-brand mower, for positive – however for those who needn’t deal with such an enormous garden, there are offers on the 0.3-acre (0.1-ha) X3 Plus for a hair over half the value. And on the opposite finish of the dimensions, you possibly can cowl three quarters of an acre (0.3 ha) with the twin-blade X7, which, due to a deal, prices the identical because the X5 on the time of writing.
There are people that get pleasure from mowing the garden; I am not considered one of them. Machines just like the Sunseeker X5 can chug away repeatedly and reliably, taking the overwhelming majority of that gig off your plate, and conserving your private home trying neat. They’re getting smarter, extra accessible and simpler to work with by the month in the mean time.
You’ll be able to nonetheless get plenty of garden mowed by a human for $2,200 for those who do not wanna heave a mower round your self – and people nonetheless do a tidier job. However the X5 has been a pleasure to have round, and Sunseeker’s smaller units might actually deal with my garden at considerably decrease price … Whereas additionally giving me that beautiful “we’re dwelling sooner or later” feeling in an uncomplicated approach for as soon as!
