How to set up a robotic lawnmower


The Content Of The Article:

In addition to the specialized trade, more and more garden centers and DIY stores are offering robotic lawnmowers. In addition to the pure purchase price you also have to spend some money for the furnishing service. But do not worry: Anyone who is not completely unskilled in terms of craftsmanship and technology can easily put a robotic lawnmower into operation on a Saturday afternoon. Here we show you step-by-step how easy it is.

Step 1: Mow the lawn

Before your new robotic lawnmower will be able to do its job in the future, you'll have to grab the lawnmower yourself again by cutting the lawn one last time by hand before setting up the robotic lawnmower. Optimal is a mowing height of four centimeters.

Step 2: Set the position for the charging station

The charging station must be positioned on the edge of the lawn at a point where the left and right sides each have at least 1.5, preferably 2 meters wide, grass strips. Thus, the robotic lawnmower can also drive from a sharper or shallower angle into the charging station and hits the contacts better. If the entrance is very narrow, it can happen that he has to correct the direction too often and eventually stops with an error message. Other important criteria for the position of the charging station:

  • There should be a power connection nearby. If necessary, you can also work with a weatherproof extension cable, but this one should then hide well, since it must remain in the garden all season
  • The place should be as level as possible and lie a bit off the creative visual axis. The charging station is visually no stain, but also no pronounced gem. In addition, it should not be visible from the street in order not to motivate potential thieves unnecessarily
  • The charging station should not stand in the blazing sun, otherwise the battery can heat up very much during the charging process. If a sunny location can not be avoided, the robotic lawnmower can also be shaded with a plastic roof. For some manufacturers, this is even part of the standard equipment or it is purchased as an accessory

Place the charging station on the edge of the lawn so that it is easily accessible for the robotic lawnmower

If a suitable place is found, the charging station is initially set up provisionally and not yet anchored with the provided earth screws. It should be so on the lawn, that the tail with the contacts is approximately at the height of the lawn edge.

Step 3: Lay the boundary wire

The boundary wire, the so-called induction loop, is a thin, low-voltage cable that shows its limits to the robotic lawnmower. The mowing lawn must be completely enclosed. Individual flowerbeds and other obstacles in the lawn, which are not so robust that the robotic lawnmower can easily bump against it, are excluded by a special laying technique: The boundary wire is laid from the edge at approximately right angles through the lawn to the flower bed or garden pond, enclosing it Obstacle and place the induction loop on the other side parallel and at a short distance to the leading cable back to the edge of the lawn. It is important that the reciprocating cable does not intersect. The magnetic fields of the cables lying close to each other cancel each other out and are ignored by the robotic lawnmower. Basically, the exclusion of all obstacles in the lawn makes sense to avoid shock noise and excessive wear of the robotic lawnmower. In front of waters you should also build a 15 centimeter high barrier.

Begin by laying the cable on one side of the charging station and, as a precaution, leave around one to two meters of cable as a reserve, in case you want to change the position of the charging station with hindsight. Then fix the boundary wire piece by piece with the provided plastic hooks on the lawn. They are simply driven so far into the earth with a rubber mallet that the cable rests directly on the turf everywhere. The distance to the edge of the lawn is different for all robotic lawnmowers. Among other things, it depends on how big the distance from the mower to the edge of the housing is.
Whether the lawn connects to a flowerbed, a wall or a garden path also influences the distance. As a rule, each manufacturer supplies a template that specifies the optimal distance for the different garden situations. Tip: In the grass corners you should lay the induction loop in a slight curve - the robotic lawnmower then does not turn, but follows the induction loop and mows the edge "in one go".

Step 4: Lay the guide cable

Some manufacturers allow the installation of a so-called search or guide cable in addition to the induction loop.It is at a point that is as far away from the charging station, connected to the outer boundary wire and then placed as directly as possible through the lawn to the charging station. It ensures that the robotic lawnmower quickly finds the electricity tap and is also very helpful to guide the device through bottlenecks. Tip: When laying the induction loop, remember the guide cable and leave a cable loop where it will be connected later. This ensures that the induction loop does not become too short later after cutting and that the guide cable can be conveniently connected to it. Depending on the manufacturer, the connection is usually made with a special connecting piece into which the three cable ends are inserted and pressed with a water pump pliers.

Step 5: Connect the charging station

After all cables are laid, they are connected to the charging station. On the back there are corresponding connections for the two ends of the induction loop and for the guide cable. Most manufacturers supply matching plugs that carry metal claws on the inside and are simply pressed onto the cables with pliers. Then connect the station to the power supply. Between the power cable and the connection cable for the charging station is a small low-voltage transformer. It is usually weatherproof, so it can be easily placed outdoors.

It continues with the setting of the mowing time: Basically, you should have your robotic lawnmower mow the lawn every day and give it a rest day per week - preferably on Sundays, because then the lawn is usually used most often. The required mowing time depends on the size of the robotic lawnmower and the size of the lawn area. Devices with so-called "free navigation", which criss-cross the lawn, have an effective surface area of ​​about 35 to 70 square meters per hour, depending on their size. The mowing performance of your robotic lawnmower can usually be found in the operating instructions. Divide the size of the lawn by the hourly output of your robotic lawnmower and set the appropriate mowing time.
Example: If your lawn area is 200 square meters and your robotic lawnmower manages 70 square meters per hour, you should set a daily operating time of three hours. Especially with winding lawns, it makes sense to add a reserve of half an hour to an hour. Whether the lawn is mowed in the morning or in the afternoon, is entirely up to your personal preferences. However, you should abstain from working at night because there are many animals in the garden at night.

Step 6: Adjust the robotic lawnmower

Now the preliminary work is completed and you can put your robotic lawnmower into operation. To do this, place it in the charging station and first adjust the basic settings via the menu. First, the default PIN code is entered and changed as soon as possible. The PIN prevents unauthorized persons from changing the settings of their robotic lawnmower. In addition, the set anti-theft protection can later only be deactivated by entering the number combination. Then, if necessary, set the current date and time

Programming the robotic lawnmower

For example, you can make the settings for the mowing times via the control panel on the robotic lawnmower

In addition, there are still different, depending on the manufacturer very individual settings for mowing. For example, some robotic robots offer the option of defining so-called remote start points. This is useful for larger, winding lawns. The robotic lawnmower alternately moves to three different points along the search wire and then begins to mow. This ensures that even lawn areas that are far away from the charging station are mowed regularly. In addition, you can adjust the width of the corridor within which the robotic lawnmower follows the search cable - he then automatically selects a slightly different distance. This prevents traces of the lawn from being created along the cable as a result of frequent driving.

Step 7: Enable theft protection

A very important function is the theft protection, since the robotic lawnmower is also doing its daily work when you are not at home. Some devices offer multiple security levels. In any case, it is recommended to activate the alarm function. If the robotic lawnmower is switched off or raised, the PIN code must be entered within a short period of time, otherwise a sustained loud signal will sound.

Step 8: Mow the robotic lawnmower

After the most important settings have been made, only the automatic mode must be turned on, and the lawnmower begins - depending on the battery level - the same with the mowing of the lawn. At the beginning, some robotic robots drive along the perimeter wire to "memorize" the lawn, then free navigation begins. In the next few days you should inspect the robotic lawnmower every now and then, adjust the mowing time if necessary and change the position of the boundary wire, if individual areas were not detected well.

Once programmed, the robotic lawnmower independently makes its rounds through the garden, creating a perfectly mown lawn

Step 9: Lay the boundary wire underground

If, after some time, the exact position of the induction loop and the search cable is fixed, you can also sink it into the ground. This has the great advantage that you can scarify the lawn if necessary without damaging the cables. Using a weed cutter, insert a small slit into the ground piece by piece, insert the cable and then close the groove again. Depending on the robotic lawnmower, the cable can be up to 20 centimeters deep in the ground.
