Description of Operation

5.1 Functional Description

STIHL iMOW 5 0 Robot Lawn Mowers - fig9

The robot mower mows the grass in randomly selected paths. It is necessary to route a perimeter wire (1) so the robot mower can identify the boundaries of the mowing area.
The perimeter wire (1) transmits a signal to the robot mower. The signal is generated by the docking station.
The robot mower identifies fixed obstacles (2) in the mowing area using ultrasound sensors and a bump sensor.
If the robot mower identifies a fixed obstacle (2), it will slow down, bump into the fixed obstacle and then continue to move in a different direction.
Areas (3) the robot mower must not navigate and obstacles it must not come into contact with must be blocked off from the remaining mowing area with the help of the perimeter wire (1).
If the robot mower identifies a blocked-off area (3), it will slow down and then continue to move in a different direction.
In mowing operation, the robotic mower leaves the docking station by itself and mows the lawn.
The robotic mower is operated by the MY iMOW® app and the buttons in the control panel on the robotic mower. Light strips on the robotic mower as well as an artificially generated voice output provide information about the current status of the robotic mower.

STIHL iMOW 5 0 Robot Lawn Mowers - fig10

If the battery’s state of charge is low, the robotic mower will search for the nearest guide wire (4) during the mowing operation. If a guide wire (4) is recognized, the robotic mower will return to the docking station by itself. The docking station recharges the battery. At least one guide wire (4) must be installed in the mowing area. A maxi‐ mum of two guide wires can be installed. If the mowing operation is canceled or the battery must be charged, the robotic mower can be sent directly back to the docking station using the MY iMOW® app or HOME pushbutton.

STIHL iMOW 5 0 Robot Lawn Mowers - fig12

Up to three starting points (5) can be specified on a guide wire (4). The robotic mower can move specifically to the respective starting point and start mowing from there.
The mowing area can be divided into several zones (example: A and B) by the guide wire (4). The zones are defined by a starting point (5). The robotic mower can be directed from the selected starting point to the left or right into the desired zone. The robotic mower can then mow specifically in the selected zone. The starting points and zones are managed in the MY iMOW® app and can be taking into account in the mowing plan.

STIHL iMOW 5 0 Robot Lawn Mowers - fig13

If there is a confined section (6) in the mowing area, the robotic mower navigates the confined area, provided that a particular minimum width is maintained between the perimeter wires. If the minimum distance cannot be maintained, a guide wire (7) must be routed through the confined section (6). The guide wire (7) then guides the robotic mower directly through the confined sec‐ tion (6) to a starting point (8). From the starting point (8), the robotic mower can mow the mow‐ ing area behind the confined section (6). The fre‐ quency at which the robotic mower returns to the starting point (8) can be managed by the MY iMOW® app and taken into account in the mowing plan.

Preparing the Mowing Area and Robot Mower for Operation

6.1 Planning and preparing mowing areas

Plan and prepare the mowing area prior to commissioning the robot mower. This enables a robust installation and smooth operation and eliminates potential sources of faults.

Planning mowing surfaces

  • Familiarize yourself with the descriptions about the docking station and wire routing in the following sections.
  •  Transfer the information to your own garden:
    – Outline of the mowing area
    – Position of the docking station
    – Routing of the perimeter wire (note described distances to the edges and wire routing cases)
    – Routing of the guide wire(s) (at least one, maximum of two)

Preparing mowing areas

STIHL iMOW 5 0 Robot Lawn Mowers - fig14

  •  Remove any objects lying around.
  • Remove metals, magnetic materials and materials that conduct electricity as well as old perimeter wires.
  •  Mow lawns with a lawn mower to the cutting height that will later be set for the operation of the robot mower. The default setting for the cutting height on the robot mower is a = 6 cm.
  • Level out holes and rough, uneven patches.
  •  Where ground is hard and dry, slightly moisten the mowing area to make driving the anchoring stakes easier.

STIHL iMOW 5 0 Robot Lawn Mowers - fig15

  • As a result of its design, the robot mower leaves a strip with unmown lawn along unnavigable areas. This strip can be used, for example, to sow flower seeds and create areas with blossoming vegetation for insects.

STIHL iMOW 5 0 Robot Lawn Mowers - fig16

  • If you want to mow without leaving an edge along inaccessible areas: Install edging stones or flagstones with a minimum width of a = 24 cm along these areas.

8.1 General requirements
Checking routing of perimeter wire and guide wire in the mowing area

STIHL iMOW 5 0 Robot Lawn Mowers - fig48

  • Make sure that the mowing area along the perimeter wire and the guide wire is flat and clear of obstacles as far as possible along the following widths: Perimeter wire (1)
    – Toward the outside: a = 37 cm (length: 1x iMOW® Ruler)
    – Toward the inside: b = 1.2 m Guide wire (2)
    – Toward the right in the direction of travel toward the docking station: a = 37 cm (length: 1x iMOW® Ruler)
    – Toward the left in the direction of travel toward the docking station: c = 1.2 m

Installing the Perimeter Wire

  •  Install the perimeter wire clockwise starting at the docking station.
  •  Do not kink, cut, put tension on or cross the perimeter wire.
  •  Make sure that the perimeter wire does not cross over a guide wire.
  •  Exception: When installing a corridor, the guide wire must cross the perimeter wire.
  •  Keep a minimum distance of 1 m to perimeter wires of adjacent robot mower installations.
  • Make sure that the length of the perimeter wire does not exceed 850 m.
  • Do not route the perimeter wire and guide wire at different depths in the soil.

Attaching perimeter wire and guide wire

STIHL iMOW 5 0 Robot Lawn Mowers - fig49

  • Use anchoring stakes to secure the perimeter wire and guide wire so that the following conditions are met:
    – The maximum distance between fixing pins must not exceed a = 1 m.
    – The perimeter wire and guide wire lie flat on the ground in all areas.
    – The anchoring stakes are sunk completely into the ground.

Installing Wire Reserves
Wire reserves make it easier to correct installed wire and give some leeway for future adaptations.
Examples:

  • A bed is extended and blocked off.

  • Bushes and shrubbery grow and the perimeter wire must be installed around the plants in a larger arc.

  • The perimeter wire was cut too short at the docking station and cannot be connected. One or several wire reserves can be planned and installed.
    STIHL iMOW 5 0 Robot Lawn Mowers - fig50

  •  Route a = 1 m of perimeter wire in parallel and closely together around 2 fixing pins without the perimeter wires crossing over each over.

  • Secure the wire reserve at the center using two additional fixing pins.

8.2 Planning guide wire and routing connection point in the perimeter wire

Carefully plan the routing of one or several guide wires in advance. Take into account the position of all guide wires when installing the perimeter wire. At least one guide wire must be installed; two guide wires may be installed.

STIHL iMOW 5 0 Robot Lawn Mowers - fig51

A guide wire (1) fulfills the following functions:

  •  Orientation for returning to the docking station (2)
  •  Moving toward a starting point (3)
  •  Splits the mowing area into zones (A and B)

Starting at the docking station (2), install the guide wire (1) across the mowing area and connect it to a point on the circumferential perimeter wire (4) that is as far away as possible.

STIHL iMOW 5 0 Robot Lawn Mowers - fig52

  • Plan the guide wire so that the following conditions are met:
    – Route the guide wire for a length of a =2 m in a straight line from the docking station to the mowing area.
    – The minimum distance between the guide wire and the circumferential perimeter wire is b = 27.5 cm
    – Route the guide wire with a minimum distance c = 37 cm (length: 1x iMOW® Ruler) in a straight line and at a right angle to the perimeter wire and connect it.
    STIHL iMOW 5 0 Robot Lawn Mowers - fig53
    – The guide wire must not cross over a blockedoff area connection.
    – The guide wire must not be connected to the perimeter wire in a corner.
    – The guide wire must not cross over a perimeter wire.
    Exception: When installing a corridor, the guide wire must cross the perimeter wire.
    – The guide wire must not be kinked or under tension, and it must not cross over itself.
    STIHL iMOW 5 0 Robot Lawn Mowers - fig54

The connection point for the guide wire must be installed during the installation of the circumferential perimeter wire (4).

  •  Secure the perimeter wire (4) at the intended areas using a fixing pin (5).

  • Place the perimeter wire (4) in a loop with a length of a = 15 cm and secure with another fixing pin (5).

  • Cut the perimeter wire (4) at the end of the wire loop with a wire cutter.
    The wire ends are connected to the guide wire at the completion of the installation. 10.1

  •  Continue to install the perimeter wire (4) around the mowing area.

8.3 Corners
Corners with a 90° angle
Corners with a 90° angle can be split into two corners with a 45° angle. Consequently, the robot mower changes its direction more smoothly and with less jerking in this area.

STIHL iMOW 5 0 Robot Lawn Mowers - fig55

  •  Route the perimeter wire in corners for at least 37 cm (length: 1x iMOW® Ruler) across the area.

Tapered corners with an angle < 90°
Divide tapered corners with an angle < 90° into two corners. As a result, the robot mower changes its direction more smoothly and with less jerking in this area.

STIHL iMOW 5 0 Robot Lawn Mowers - fig56

  •  Make sure that tapered corners are not at an angle less than 90°.
  •  If the angle is less than 90°: Split the angle.
  •  Design one corner with an angle greater than 90°. Then route the perimeter wire in a straight line for at least 37 cm (length: 1x iMOW® Ruler).
  • Then design a corner with an angle greater than 90°. Subsequently route the perimeter wire in a straight line for at least 37 cm (length: 1x iMOW ® Ruler).

8.4 Navigable area
The robot mower is able to navigate areas directly adjacent to the mowing area if the difference in height between the navigable area and the mowing area is no more than 1.5 cm. The ground must be solid and there must not be any obstacles.
Examples:
– Patio
– Paved path
– Edging stones or flagstones
Edgeless mowing is enabled by maintaining a short distance between the perimeter wire and the navigable area.

STIHL iMOW 5 0 Robot Lawn Mowers - fig57

  • Route the perimeter wire parallel to and without any distance from the navigable area.
    The maximum difference in height between the navigable area and the mowing area is a = 1.5 cm

8.5 Unnavigable area
An area is unnavigable if obstacles close to the ground protrude into the mowing area, the ground is not solid or is very uneven and if the difference in height between the mowing area and the adjacent area is more than 1.5 cm.
Examples:
– Wall or fence
– Hedge or shrubbery with branches that grow close to the ground
– Stone garden or gravel path
– Heavily rooted or uneven ground

STIHL iMOW 5 0 Robot Lawn Mowers - fig58

  •  Route 37 cm (length: 1x iMOW® Ruler) of perimeter wire parallel to the unnavigable area.
  • If the unnavigable area is within the mowing area: Block off the unnavigable area with a restricted area.

8.6 Water areas
An increased wire distance must be maintained to water areas if the water area has not been blocked off from the mowing area by a fixed obstacle with a minimum height of 10 cm.
Examples:
– Garden pond
– Pool
– Stream or watercourse

STIHL iMOW 5 0 Robot Lawn Mowers - fig59

  •  Route the perimeter wire at a distance of a = 1 m in parallel to the bank area.
  •  If the water area is within the mowing area: Block off the water area with a restricted area.

8.7 Drop-off edge
Keep an increased wire distance to drop-off edges if the drop-off edge has not been blocked from the mowing area by a fixed obstacle with a minimum height of 10 cm.
Examples:
– Stairs
– Retaining wall
– Tiered slope

STIHL iMOW 5 0 Robot Lawn Mowers - fig60

  • Route the perimeter wire at a distance of a = 1 m parallel to the drop-off edge.

8.8 Restricted area
Areas within the mowing area that must not or cannot be navigated by the robot mower must be blocked by a restricted area.
Examples:

  • Bed without a fixed border with a minimum height of 10 cm
  •  Garden pond or pool without a fixed border with a minimum height of 10 cm
  •  Obstacles that the device must not come into contact with:
  • Obstacles that are not strong enough
  • Obstacles below a height of 10 cm

To ensure a robust mowing operation, restricted areas must not have any inwardly curved shapes.

STIHL iMOW 5 0 Robot Lawn Mowers - fig61

  • Route the perimeter wire (1) away from the edge toward the restricted area. Make sure that the following dimensions are maintained for the restricted area:
    – Minimum distance to other perimeter wires a = 55 cm
    – Wire distance b = 37 cm (length: 1x iMOW® Ruler) (for water areas and drop- off edges, b = 1 m)
    – Minimum diameter of the restricted area: 74 cm

STIHL iMOW 5 0 Robot Lawn Mowers - fig62

  • Route the perimeter wire (1) around the area to be blocked off.
  • Route the perimeter wire (1) parallel and close together back to the edge without the perimeter wires crossing each other.

8.9 Fixed obstacle
A fixed obstacle within the mowing area does not have to be blocked off by a restricted area if the obstacle is at least 10 cm high. The obstacle is identified by the ultrasound sensors and the bump sensor.

STIHL iMOW 5 0 Robot Lawn Mowers - fig63

  •  A fixed obstacle with a minimum height of a = 10 cm does not need to be blocked off.

8.10 Confined section

STIHL iMOW 5 0 Robot Lawn Mowers - fig64

The robot mower navigates all confined areas, provided that a minimum width (a) is maintained between the perimeter wires (1).

  • Route the perimeter wire (1) as illustrated and make sure that the following dimensions have been maintained:
    – Minimum distance between the perimeter wires (1) in the confined section: a = 2 m
    – If the confined section is restricted by side obstacles: Include an additional distance of b = 37 cm (length: 1x iMOW® Ruler)

  •  If the minimum distance a = 2 m between the perimeter wires (1) cannot be maintained:
    Route a guide wire through the middle of the confined section.

8.11 Corridor
Functional Description

STIHL iMOW 5 0 Robot Lawn Mowers - fig66

Use a corridor (1) to overcome confined sections in a precise way or to define passageways. The corridor divides the mowing area into a main mowing area (A) and another mowing area (B).
The perimeter wire (2) is routed without interruptions. It forms a corridor at the transition from the main mowing area (A) to the other mowing area (B).

STIHL iMOW 5 0 Robot Lawn Mowers - fig67

Wire loops (4) indicate to the robotic motor when a corridor starts or ends.
A guide wire (3) must be installed in the middle of the corridor.
A corridor must be followed by a starting point (5) within the mowing area (B). Otherwise, the robotic mower will not find its way from the main mowing area (A) through the corridor to the other mowing area (B). Starting points and their approach frequency can be set using the MY iMOW® app.
