Installation of a robot lawn mower
Among the great many types of instruments and garden equipment intended for mowing grass, gazonocosyl robots are the most “young”, their mass distribution began only in recent years. But at the same time this is the most convenient tool: any other technique is used periodically and requires the presence of the operator. It is impossible to say that the mowing is difficult work, but it takes it pretty time and has to spend it on the processing of lawns constantly-at least once every two to three weeks you will have to allocate several hours for this work. Everything is easier with the robot. it is enough to carry out its installation and configuration once. And then. “He himself”.
In Europe, sales of such equipment reach 300,000 units per year, in our country it is less common. in a year the number of models sold is calculated by hundreds. But the prospects of this market are great.
The robot mows in constant mode. therefore, the grass does not have time to grow and the lawn at any time looks “like new”. When using the robot, the grass is less damaged: only its ends are cut off. The issue of disposal of the cut offs also does not arise. they remain on the lawn, where they are very quickly overwhelmed and turn into free fertilizer. The installation of the robot allows you to reduce the cost of further processing of lawns. the owner of the owner and its means are saved.
Modern gazonocosyl robots are designed to work in areas with an area of several hundred to several thousand square meters. It produces their rather limited number of companies: the technique itself is not easy and requires the organization of not only sales, but also training specialists in their warranty and service maintenance. over, many dealers also offer a set of services for installing and setting up gazonocosyl robots. In principle, there is nothing complicated about this, but, of course, the specialist will cope with the installation and conduct preliminary tuning faster and better: he has the necessary equipment and experience.
In our master class, we will consider the installation of a gazonocos robot on the example of the Automower 420 model from Husqvarna. In the lineup of six Husqvarna mowers (read their review here approx. Ed.) This model is fourth “in terms of difficulty”. But the main emphasis will be on the features of the installation common to all robotic lawn mowers. In general, all manufacturers are the same, they have “nuances”, but they are not a secret, everything is indicated in the instructions for a specific model.
We will also talk about other “subtleties”, but in passing. In the model rows of even one manufacturer, automatic braids differ primarily in the maximum allowable processing area. And the more it is, the more “bells and whistles” and the model, especially in terms of settings. It makes no sense to make Accent: different manufacturers have the structure of the settings menu varies. over, even the same models, but released at different times, have differences. the technique is improved, individual nodes, electronic blocks and versions of firmware are changing, new opportunities appear. Many models are also able to work with various additional equipment, which is installed optionally.
Selection, restrictions and preparation of the site
As already mentioned, gazonocosyl robots-a complex technique. This has its advantage. A potential buyer can count on receiving a detailed consultation from the seller based on the features of the site. It is enough to know what exactly it is worth paying his attention to.
The main parameter is the maximum allowable processing area. It is indicated subject to continuous operation of a mowing with interruptions for charging. It is usually assumed that the mower works around the clock (but not always, some manufacturers still have restrictions on the maximum time of work during the day). Of course, this parameter is indicated under “optimal conditions”. a new battery, a flat lawn of a relatively simple shape with a minimum of obstacles. So there will not be some kind of “area” in the area, and the actual time of work sufficient to obtain the desired result can be configured during operation.
The shape of the site does not play a particular role, but there are some restrictions on the angle of inclination (its maximum allowable value is indicated in all models of mowers), as well as the minimum width of “narrow places”, if any, there are any. In general, before choosing a robot model, there is a reason to draw a site diagram and make approximate measurements. Most lawns “fit” into standard circuits, even a relatively simple model can process them.
As for the preparation of the lawn for installing a gazonocosel robot, it is almost no different from preparation for any other mowing equipment. It is necessary to provide an even surface without pits, where rainwater usually accumulates, remove tubercles and extraneous objects that can fall under the knives. Before the first launch, if the grass has grown high, it must be cut to any other device.
Planning and preparation
Automower installation process must be carefully planned. We recommend that you draw up a scheme of the working area with all the obstacles and relief features on your site. Using such a scheme, you can easily determine the perfect location of the charging station, restrictive and guide wires.
Select a place to accommodate a charger on your site. Additional information can be found in an article where it is best to place a charging station.
Also in advance, select the junction of the guide wire with a restrictive one, and when laying a restrictive wire, leave a loop 10 cm in this place in this place. This will greatly simplify the connection of the guide and restrictive wires.
So that the grass does not interfere with the laying of the wire, it is recommended to first cut the lawn.
Laying the wire
Laying the restrictive wire begins and ends at the charging station. Leave an additional 50 cm wire to connect to the charger.
Lay the restriction of the perimeter of the entire working area.
Part of the restrictive wire going to the charging station should be completely laid outside the charger (see. Option 1 on the image). If you need to place the charger partially outside the working area, the wire can be laid under the base of the charger (see. Option 2 in the image). Nevertheless, it is not recommended to have more than half of the charging station outside the working area, t.to. This will complicate the lawners-mowing robot Search for the charger (see. image).
Do not lay the wire with turns at an acute angle (more than 45 °).
Make sure that the wire is located at the right distance from obstacles, and if necessary, create islands, passages and secondary sections.
Fasten the wire with fixers or deepen it into the ground:
- When laying the wire on the ground with the help of fixers in a few months, it will be completely hidden under the grass. Place the latches in even areas at a distance of about 70 cm from each other. Check that the wire is securely fixed on the ground to prevent the gas mowing stuck. If, due to the irregularities of the site, the wire freezes in the air, use additional latches-otherwise the lawn mower may cut the wire.
- If you want to deepen the wire into the ground, with the help of a shovel, make a small recess of a few centimeters on the lawn. Lay the restrictive or guide wire in the ground to a depth of 1–20 cm. We recommend this option if your lawn is uneven or if you need to hide the wire.
After laying the restrictive wire around the perimeter of the entire working area, connect both ends of the restrictive wire to the charger.
Distance from the restrictive wire to objects
Since the lawn mower always moves through the wire before stopping, the wire should be laid at different distance from obstacles. To determine the correct distance, use the Automower line included three marks in the kit: the minimum, average and maximum distance. Suitable distances depend on the model. Information about accurate distances for your model see. In the operating manual.
- Lay a limiting wire at a distance of 35 cm from obstacles with a height of more than 5 cm.
- Lay a limiting wire at a distance of 30 cm from obstacles 1-5 cm high.
- Lay a limiting wire at a distance of 10 cm from obstacles with a height of less than 1 cm.
- To solid objects, such as fences and walls, you should leave the maximum distance. otherwise the lawn mower will hit a solid facility at every turn.
- To floral flower beds and shrubs, where there is no risk of blow, it is enough to leave the average distance. With a lower distance, the lawn mower can go beyond the lawn and get stuck. If the distance is too large, downshole will remain along the edges of the lawn.
- To the paved tracks located on the same level with the lawn, it is recommended to leave the minimum distance along the ruler. When turning, the lawn mower will drive slightly on the track, while mowing the entire grass along the track.
- On gravel paths, the lawn mower can get stuck, so choose the average distance.
- On the paths with hard coating, the lawn mower can move calmly.
- For safety reasons, it is necessary to install a barrier with a height of at least 15 cm around the pools or ponds.
These distances should be used as a guideline. After the trial period of the mowing, you can move the restrictive wire so as to improve the results of the lawn mower.
If there are sites on the lawn for which the lawn mower should not call, for example, flower beds and alpine slides, create islands using a restrictive wire.
Passages are used to connect two parts of the working area, between which the lawn mower can move. In the presence of a guide wire in the aisle, the minimum distance between limiting wires is 60 cm. If the working area has a passage where there is no guide wire, the minimum distance between the limiting wires is 2 m.
The secondary section is formed if the working area consists of two sections not connected by the passage. The working area with a charger is considered the main site.
How the Robot Lawn Mushroom robot works on the example of Stihl RMI 422 P
In order to find out the answers to this question, I asked the company for a sledgehammer.ru give me a mower for a test of some robot. A week later, I had a huge box with a fairly expensive Stihl RMI 422 p robot in my country house.
Most gazonocosyl robots cost from 35 to 150 thousand. Almost all of them work according to one principle. A restrictive wire is laid on the site (it and the pegs for attaching to the ground are included in the kit of the robot), with the help of which the territory is determined where the robot works. The beginning and end of the wires are connected to the base (by the way, until the wire is connected and the base is not included in the network, the robot generally refuses to start). Those places, inside the territory of the mowing, where the robot cannot be climbed (flower beds, pools, and so on) are enclosed by a wire, and in places where two fragments are folded together and go there and back, the robot passes freely, without feeling restrictions.
Most robots have only two sensors: a collision sensor (this can be either a movable bumper or an internal sensor) and a rain sensor. Very expensive robots have an ultrasonic obstacle sensor, for some robots, such a sensor is sold in the form of an option.
Almost all robots move randomly: the robot reaches the wire and turns to an arbitrary corner. As far as I know, only Bosch robots build a map of the site, but judging by the reviews, the result of their meaningful movement is often even worse than a chaotic in other robots.
Any robot coser uses the charger, while he knows how to find it (he gets to the wire and rides along the wire until he meets the base), charge and continue the mowing after charging.
Typically, robots of mowers have two large drive wheels (20-22 cm) and one or two videos (8-9 cm). Stihl has two videos.
Many manufacturers to the detriment of cross.country ability and quality of mowing make the robot as safe as possible. so that he could not injure the hand of the child lying on the grass or cut off the tail to the cat. To do this, he underestimates up to 2.5 cm clearance in the front of the robot and knives are protected as much as possible with combs and metal elements. All this leads to the stuck of the robot and the fact that the robot is clogged with grass. It seems to me a situation when a small child lies on the grass, and a stupid cat substitutes the tail of a mower almost incredible. Ordinary robots have a clearance of 5 cm and as soon as the robot meets something thicker, he immediately turns around.
How to install your GARDENA SILENO robotic lawnmower
As you can see, STIHL has no protection and it’s good. This model has two metal knives on the disk, the width of the mowing 20 cm is cut.
Other models often make three interchangeable bilateral knives, freely rotating on the disk. In the photo Worx LandxScape 600 LX790.
The robot knows how to mow on schedule. In the simplest robots, the schedule is set automatically: the area of the site is set, on the basis of which it is calculated how many days a week (from 2 to 5) and how many hours (from 2 to 10) mow. You can only configure the start time. In more advanced robots, the schedule can be adjusted in more detail. Of course, the robot can be launched manually (or yet you stop it, or for the indicated number of hours depending on the model).
Many robots have a setting of mowing zones. The point of the restrictive cable is programmed, where the new zone begins. After that, you can launch mowing of certain zones or sequence of zones (to find the desired zone, the robot just goes along the wire remembered, and then begins to mow).
There are robots equipped with Wi-Fi. They set up and control from the application on the smartphone (you can start and stop mowing, send the robot to the base, set the schedule). Perhaps the main plus of Wi-Fi at the robot. Work and problems notifications. If the robot gets stuck (and it necessarily gets stuck), a push notification will come to the phone.
Let’s get back to the Stihl robot and answers to my questions.
This robot does not have Wi-Fi, all control through a large LCD screen. There is a setting of zones, many additional “chips” like finding a wire break.
The main impression: Robot “rushing like a tank”. He turned out to be completely in my way of my bumps, pits and bumps. For the first time he got stuck when he ran into the pit so that one wheel hung over it, and the second hung in the air. This is where the whole stupidity of the robot manifested itself: he simply twisted endlessly with wheels and a mowing disk, thinking what was mowing. I was surprised that the programmers did not guess that if the robot “rides to the wire” for too long, then something went wrong. A couple of times the robot stuck, finding himself in the corner of thick grass. He began to “fray” left-right, but he could not drive, and then he couldn’t get away. But in general, the robot travels along an unprepared area and rarely gets stuck. All places of potential stuck can be corrected.
My second question was about the density of the grass that the robot might mow. Mows dense wild grass “with a bang”, but it is important that the grass is not high, in it it can get stuck. In general, in the instructions for any robot it is written that before using it, the lawn must be mowed with an ordinary mower. Ideal for the robot, when it cuts a little bit every time, preventing the grass from growing. For the lawn itself, this is also good, because the robot does not collect grass, but leaves it on the lawn (when the trims are small, they will quickly overwhelm, turning into fertilizer, and large can be visible and they will rot longer).
The main question: is it really possible to use the robot only once a week, removing it when there is no one in the country. Answer: Not always. As I wrote above, it is desirable that the grass in front of the mowing be low (perfectly. up to 5 cm). In May and early June, the grass for a week grows 10 centimeters by 10. The robot will be able to mow such grass, but inevitably sometimes it will get stuck.
How I chose a gazono-core robot.
The area of my site is about 10 acres. I do not grow strawberries and tomatoes, in the country my family and I prefer to rest. Accordingly, the whole thing is sown with a good Danish lawn mixture. And everything in it is great except that at least once a week the grass needs to be mowed. At first, this is cool, but last year I was frankly tired and decided to automate the process by buying a gazono-bass robot. The choice fell on Bosch Indego. advertising, brand fame and urgent recommendations of the seller in the store have done their job. It was assumed that this miracle of technology mows the lawn very smoothly, literally a strip in a strip, and not chaotic, plus creates a map of the garden and carefully cuts the grass around the perimeter. Unfortunately, in fact, everything turned out to be not so rosy. Firstly, in addition to grass, fruit trees also grow on the site-about 3-4 meters from each other. They, like the whole territory as a whole, I carefully “circled” the perimeter restriction with a wire. The instructions said that after the first 2-3 cycles, the robot will remember everything and will begin to do its work according to the verified algorithm. However, instead, the mower went around the perimeter and near the trees, then crawled a meter to the side and stopping forever. It was strongly impossible to endure this, and I tried to remove the wire laid around the trees. After that, Indego earned more or less normally, but at some point he stopped again. This happened with a frequency of 2-3 days, I had to regularly reset on factory installations. While the grass is not very high, the mower cut down quite high quality and evenly. But as soon as the grass grew up, for some reason the robot began to carefully fold the mowed segments 2-4 centimeters long right on top of the lawn. And you have to collect this dried hay with a hand. The advertising story with a haircut overlapping, of course, was also not so ideal: as the settings do not turn, and the strip of not cut grass constantly remains here and there. Now a couple of words about the quality and service of Bosch. Five days after the start of use, the Indego broke the wheel, and I had to take it to the service to the new apparatus only after 35 days, and it was also faulty: the wire of the perimeter was not determined. First lay 300 meters wires, and then immediately get it back from the ground. then another pleasure. In a word, it turned out that I bought a mower in May, and actually began to use only in August. Along the way, I had to manually finalize the design of the wheels, since they were constantly falling off, and spare knives in online stores with the day with fire cannot be found. As a result, the miracle of equipment went back to the manufacturer, since at least the money was returned quickly. I approached the choice of replacement more responsibly. I independently re.read a bunch of articles and reviews on the Internet. And for 2 months now, Robomow has been crawling around my site. At first I wanted to buy a RS622 model, but it was not available, I had to take RS612. I was very afraid to make a mistake again, but in the end I did not regret it: if you compare both the devices of the forehead in the forehead, then this is like “Zaporozhets” and “Mercedes”. Robomow. a device of a completely different level. The first thing that surprised is the menu. At first it seemed that there was somehow not enough settings, but in reality they are enough. The mowing schedule is adjusted very simply and quickly: you need to choose the time when the robot will not work, and mark the days. Do this enough once, and not every three days immediately after resetting the installations, as was the case with Indego. In addition, the mowing has a very successful modular design. If the hands grow from the desired place, then individual parts can be easily replaced independently. Agree, there is not always time, desire and opportunity to carry 20 kilograms of iron and plastic to the service. The rain sensor is also built in RS612: when a decent amount of water gets on the housing, the robot stops itself. And that’s right, because if you mow in the rain, then the grass is stuffed between the knives. To pick it out from there. pleasure below average. In the Bosch model, such a function is not provided. Well, most importantly: the RS612 lawn mows is much more accurate, although sometimes small “islands” still remain. It is treated by an increase in the intensity of mowing. The 1000 m 2 I subsequently increased to 1350 m 2 indicated at the beginning of the recall. probably the case, t.to. In the specifications, the recommended area of the lawn is 1200 m 2. But Robomow separately bakes 4 zones of different shapes, and Bosch developers obviously believe that everyone has one perfectly even rectangular or square lawn without a single bump. A robot can be manually controlled from a smartphone on iOS or Android. In truth, mowing is not at all interesting, but it is convenient if necessary to move RS612 from one place to another. Without certain shortcomings, of course, of course. The assembly quality, although good, after a week of use, crept in one of the engines. I decided to lubricate it myself. The modular design allowed to easily remove the motor with your own hand in less than a minute. There is a lubricant in the gearbox, but it is not enough, and almost everything is smeared around the edges, and the gears are empty. It would be good if the manufacturer had paid attention to this. nevertheless, not everyone is ready to climb into the bowels of the robot. The second point is that the declared Robomowo function of the line of the lawn works only along the paths or the edge of the lawn, if you need to shave the grass along the fence or at home, there will be a strip of 3-5 centimeters. Bosch without this function, leaves 11-15 cm.
But in the end, if you compare Bosch with Robomow, then at an almost equal price in dollars, Robomow clearly wins.
What are the sensors for
In the housing of the gazono-shower robot there are sensors with various functions responsible for:
- tracking the site during processing;
- interaction with a restrictive cord;
- recognition of the already passed site;
- determination of an obstacle that has a height of more than 10 cm.;
- Identification of precipitation. with rapid drops on the body of the apparatus, a command will receive a command to return the device to the base. But in the premium models, the case is reliably protected from moisture and such a device will continue, and even more-about bad weather the robot gasone-gunner can transfer to you to your smartphone, and you yourself can already make decisions and manage functions through the phone in such a period if you do not have it on place;
- If the robot rolled over, then the device shutting off the device and knives will stop, and an error signal in the work will be given to the station;
- In the case of the theft of the robot, the built-in system of “its own or foe”. She is responsible for recognizing the base. But such a function is on expensive models.

SEGWAY NAVIMOW is represented. the first smart lawn mower that does not require a restrictive cable
Segway-Ninebot, which is a partner of Xiaomi, introduced a robotic lawn mower called Segway Navimow. The device uses the EFLS positioning system (Exact Fusion Location System) to achieve accurate positioning at the centimeter level and may plan the optimal route for haircuts of the site. Thanks to EFLS technology, there is no need for restrictive cables around the perimeter, as in most robotic lawn mowers.
In addition, the SEGWAY NAVIMOW lawn mower also received many other sensors to help in positioning, such as a geomagnetic sensor, odometer, differential barometer, and so on. The device can work stably even with a temporarily weak satellite signal.
Special technology allows you to instantly stop blades to protect children or pets from injuries. The robot is also equipped with an ultrasound sensor, which can perceive the environment in real time, safely bypass obstacles and avoid collisions.
My Experience with the Husqvarna Automower 450X For One Full Summer
Segway said that the maximum noise level when using Navimow is only 54 dB, which is lower than most of these robots. Before that, a record low level was 58 dB.
The line contains four models designed for lawns with an area of 500 to 3000 square meters. SEGWAY NAVIMOW is expected to go on sale next year. Segway Navimow H500E, H800E, H1500E and H3000E will be 1199, 1499, 1999 and 2499 euros, respectively.
Instead of a preface:
Hello! My name is Vyacheslav Golitsyn, and I am geek! It still began at school, my friends from the physical education team planted on this. At breaks, stealthily in the toilet and around the corner of the school, we discussed new gadgets and schemes for bugs-radio transmitters. I thought I was just pampering, but then I could no longer jump off. The electronics that I was going to fix in the house no one had ever seen a working one, during the next enchanting revelry, I was cruelly killed by I killed the electronics 302 tape recorder. I was punished, but I could not completely abandon my pernicious habit, so I became a secret geek, but even in the radio club they didn’t take me for my own, yes, there are little noticeable in clubs, because of the pathos everything is upside down. When I exchanged my new snowman for a textbook A.Marchenko and the designer of the car receiver, I realized that I was swinging to the bottom! They began to recognize me in the face on radio markets and in electronics stores, I read “Youth Technique” and mediocre forums at night on Dialup’e. I started wearing glasses with simple glasses, t.to. everyone called me “Ochkarik”. Even my own father once put me 3 in classmates. Finally broke when the girl threw me, then it suffered me I bought a new soldering station, and my account on Aliexpress began to demand the blood of my modest salary.
Then life somehow got better Family, children, and for several years now I have been in the eyeballs, but every day I have been reading a habr (now Hiktayms). I am a very middle level manager, I am working in the office like everyone else. Alas, I have no technical education, but when I read an overview of the new gadget, mini-computer or automation board, a huge number of ideas are already being formed in the mind where it could be applied (the automation of the office toilet is not offered). After a short flight of imagination, you usually follow the order and the languid expectation of the foreign miracle of the wonderful. During the time, the long.awaited load passes all circles of hell of the sorting centers of the mail, the romance gradually from the new model of modern genius of technical thought disappears. So it was with Raspberry Pi, Arduino, a small box with sensors and wires. But then pain appeared. Her name is a summer house, or rather a lawn in the country.
Mow the lawn. do not chop firewood. And do not drink tea, and do not go through the quests, and do not go for beer. Well, you understand.
You ask: why the lawn mower, the summer is ending, and we have long winters? It’s not for nothing that people say: “The Winter is coming. “”. Perhaps the answer is banal laziness or curiosity, it is possible. all together, but maintaining the lawn in a beautiful form. the task is not from simple even with modest sizes of land, which are represented by your humble servant. I decided to combine the active desire to know the new Raspberry Pi Model B Arduino chermet free will, heroism, professionalism, capitalism, sure and cataclysm.
The decision was considered for a long time, examined the option of buying a finished mower, but came to the conclusion that it would be most convenient to cook the trolley itself and attach the internal combustion engine from a hand lawn mower.
The cart is driven by two engines with gearboxes from the VAZ-2108 wiper (import substitution in action). The engines have not two brushes on the collector, as I was familiar, but three. I never figured out why the third brush, but the fact that one of the wires was connected to the case, and the engines had to move in different directions for moving forward was forced me to isolate one of the engines from the frame.
With engines, a difficult story: in an attempt to understand the device of the engine, I dismantled one of them. this was already a harbinger of the fact that the engine with all its horsepower would go to the Khalosar of the Great Tabantner forever. In general, “who swallows the catfish. does not know problems,” bought a new engine and continued to bicycle and cattle.
Wheels from the cart purchased in the construction market. The engines were connected through the Monster Motor Shield, but according to a good tradition, this fee ordered to live long after the power supply to the contacts of the withdrawal. Vanguyu Kholivar in the Комментарии и мнения владельцев about the fact that with crooked hands and you should not start doing anything, but what if the heart asks? In general, catfish is not a drama: we place an order for the same fee, but for now we can go through two relay, t.to. engines in the first pairs can spin only one way. In general, given the lack of need for a PWM, you can make a H-motor based on a block of 8 relay for Arduino. And how do you feel about this, dear reader?
Engine control and sensors survey (ultrasonic distance sensors and encoders on wheels; in version 1.1: Infrared obstacles sensors, button in the front bumper) Arduino Mega 2560 is carried out.
Andurin (my wife continues to be so called so) connected to Raspberry Pi via USB (all modest communication on Serial Port). Also, a webcam is connected to the raspberry (in version 1.0 for output pictures via motion) and wi-fi whistle.
Robots of the lawn mower
Alas, mowing robots lag behind robots-perpeters by ten years old. They have no lidars and cameras, they do not know how to build a map of the territory.
Perhaps some of this has models, but all relatively affordable models at best have the only impact sensor built in the front bumper, and all navigation is made using a wire that limits the territory of the mowing (the wire will have to be laid not only by the perimeter of the territory, but also to circle each flowerbed and every bush if the robot should not crawl to it).
The robot coser moves randomly through the territory limited by the wire. Thanks to multiple passages in one place, mowing throughout the territory is achieved (this is how the very first robots-sprayers worked).
Most robots-kosillers have a Wi-Fi and an application in which you can create a mowing schedule, but there is no map and movement settings.
The width of the mowing in most models does not exceed 20 centimeters. Three small knives spin freely on a small disk located in the center of the bottom or shifted to the side.
The robot coser mulches the grass and leaves it on the lawn, where it turns into fertilizers.
All gazonocosyl robots are designed for a certain territory of the lawn and often it is very small (for example, the Robomow RX12U model is limited by two and half hundred hundred).
A separate issue concerns patency. Most robots have two large wheels from behind, and a small wheel-roll in front. Of course, the robot will ride perfectly on an ideal lawn, but when the Earth, like mine, is not perfectly related, there is great doubt that the robot will not get stuck.
for gazono-shit robots are still quite high (although this device is not much more complicated than a conventional battery-derivative brake). The cheapest market for the Landxcape 600 LX790 robot market costs about 43 thousand.
It is designed in the territory of up to 6 acres, has a width of the mowing 16 cm and a mowing height of 30-60 mm (installed by a large mechanical handle on the case). The robot knows how to return to a recharge, there is a rain sensor that makes the mowing stop the mowing in wet weather. The kit includes 150 meters of a restrictive wire and 210 pegs for attaching it to the ground.
The Worx Landroid S 390 more expensive robot for 48 thousand supports the size of the lawn only up to 3.9 acres.
Even a robot for 83 thousand Worx Landroid M Wr141e can mow only five acres.
Dear robots-toe are not very “smarter” cheap. Here, for example, Husqvarna Automower 430x for 360 thousand (!) rubles.
Despite the high price, there are still no lidars and cameras, except that the headlights “for beauty” added the size of the territory of the mowing to 32 acres.
I don’t know how quickly modern technologies will get to robots-muckers, but so far they are quite simple. Of course, ideal mowing can be achieved with chaotic movement, but when robots, like modern robots, vacuum cleaners equipped with navigation means, will learn to build terrain maps and will move consciously, not chaotic, well will be good.
