To the world of robotic lawn mowing with the FriendlyRobotics Robomower. Thank you
for purchasing our product. We know that you will enjoy the extra free time you will have while
using Robomower to mow your lawn. When installed and used properly, Robomower will
operate safely on your lawn and provide you with a quality of cut matched by few mowers of
any kind. You will be impressed with your lawns’ appearance and best of all Robomower did it
for you.
IMPORTANT!
The following pages contain important safety and operating instructions.
Please read and follow all instructions in this manual. Carefully read and
review all safety instructions, warnings and cautions contained in this manual.
Failure to read and follow these instructions, warnings and cautionary
statements may result in severe injury or death to persons and pets or damage
to personal property.
A Basic How It Works
A small wire, called the perimeter wire, is placed around the perimeter of the lawn and any other areas
where you do not want the mower to enter. A small signal is generated from a device attached to the
perimeter wire, called the Perimeter Switch. When turned on, this signal is carried through the perimeter
wire, creating what we define as a virtual wall. The virtual wall is visible only to the Robomower, keeping
the Robomower where you want it, on your lawn. The perimeter switch must be turned on to activate the
perimeter wire before the Robomower will operate.

Safety Features
1. Child Guard / Safety Guard
This menu option offers a safety feature to help prevent children or others not familiar with the
safe operation of the mower to operate it freely.
2. Lift Sensor
There is a sensor located on the front caster wheel of the mower. In the event the front of the
mower is raised approximately 1-inch from its resting position on the ground during blade
operation, the blades will stop rotating immediately (< 1 second).
3. Sensor Equipped Bumpers
The front and rear bumpers are equipped with contacts that will activate when the mower
strikes a solid, fixed object when that object is at least 6-inches in vertical height from the
supporting surface of the mower. When the bumper sensor is activated, the mower will stop
movement in that direction and reverse itself away from the obstacle. In manual blade
operation, bumper activation will stop the rotation of the blades immediately (<1 second).
4. Emergency Stop Switch
Located on the top outer surface of the manual controller, red in color. Pressing this button at
any time during operation will stop all mower movement and stop the rotation of the blades
immediately (<1 second).
5. Automatic Mode Recognition
The Robomower is designed so that it cannot be operated in the manual mode while the
Manual Controller is in its’ pocket and it cannot operate in the automatic mode while the
Manual Controller is removed.
6. Two-Step Operator Presence Control
While in manual mode, it requires two independent finger actions in order to engage the
mower blades. Once engaged, the mower blade button must remain depressed to continue
blade operation. Once released, the two-step engagement process must be repeated.
7. Electronically Controlled Charging System
The Robomower is equipped with an on-board charge control system. This allows you to
keep the charger connected at all times, even after the battery is fully charged. The control
system will prevent an overcharge to the battery and keep it fully charged and maintained for
the next use.
8. Sealed Power Pack
The power pack that operates the Robomower is completely sealed and will not leak any type
of fluids, regardless of position. In addition, the power pack contains a one-time-use fuse in
the event of a short-circuit or power malfunction.
SAFETY
Page 6
9. Perimeter Switch and Perimeter Wire
The Robomower cannot operate without a perimeter wire installed and activated through the
Perimeter Switch. In the event the Perimeter Switch is turned off or otherwise fails to function, the
Robomower will stop operating. Likewise, should a break in the perimeter wire occur the
Robomower would again stop operation. A break in the perimeter wire prior to operation will
prevent the Robomower from operating. The Robomower can only operate within the boundary
of the perimeter wire.
10. Auto-Off Perimeter Switch
The auto-off feature of the perimeter switch shuts down the perimeter switch operation after
approximately 5 hours of continuous operation. This is typically 1 to 2 hours after which a fully
charged Power Pack will need to be re-charged. This helps to prevent unauthorized persons from
attempting to re-start the Robomower after it has completed its’ operation.
11. Over-Current Monitoring Protection
Each of the three blade motors and each of the two wheel drive motors are monitored
continuously during operation for any situation that may cause these motors to over-heat. In the
event this is detected, the Robomower will stop operation of at least that motor and possibly the
mower itself and indicate that the motor is cooling down. While unusual, this may happen when
the mower is put in grass that is severely overgrown; the underside of the mower is clogged from
poor cleaning maintenance; the mower has encountered an obstacle that is unable to activate the
bumper sensor preventing it from moving; or a problem landscape area has caused the mower to
get stuck and is preventing it from moving.
WARNING!
!
This warning symbol will be found at several points throughout
the pages of this owner/operator manual. It is intended to

Perimeter Wire Setup
Chapter 1
Page 9
1.0 Where To Start
In order to determine the best location to begin the setup, it is best to first make some basic
decisions based on your lawn. For each zone that is set up, allow for placement of one
Perimeter Switch for that zone. Find a convenient spot outside the perimeter of each zone that
is relatively easy for you to access. A spot sheltered from the elements is preferred
1.1 Using The RoboRuler
There are two basic measurements that are used on the RoboRuler. The shorter distance is
used along perimeter edges where the area outside the immediate perimeter (about 12 inches/30
cm) is free of obstacles and is the same relative height as the perimeter edge. The longer
distance is used along perimeter edges where the area outside the immediate perimeter has
obstacles or differences in the height along the perimeter edge. See Figure 1.1.

as an obstacle.

basic level and free of obstacles.

1.2 Starting The Perimeter Wire
Tear out the perforated center piece on the perimeter wire box. Puncture the plastic covering
with your finger and feel around inside the center of the wire spool for the end of the wire. Pull
the wire end out of the box. The box is designed as a dispenser for the wire so do not remove
the wire spool from the box. After reviewing the illustrations and instructions in the following
pages you will be ready to lay out the perimeter wire and start pegging it to the ground. Figure
1.2
Leave enough wire at the beginning, where the Perimeter Switch is going to be located. Use the
RoboRuler to help guide you on placement of the wire along the perimeter. Use a minimum
number of pegs at this point, as you will want to test the wire position at the end of the setup.
See Section 2.5 for details on testing the setup.

WARNING!
!
Damage to the eye is possible. Use proper eye protection
and wear appropriate work gloves when hammering the
pegs. Hard or dry ground may cause pegs to break when
driving them in. In extreme cases, watering the lawn where
the pegs will be driven can be beneficial.
1.3 Fastening The Wire To The Ground
Add pegs in to pull the perimeter wire down to the ground surface, below the grass tips Figure
1.3
Add pegs in to pull the perimeter wire

1.4 Corners & Sharp Turns
Care must be taken not to create a turn sharper than 90 degrees when setting up the perimeter
wire. A turn sharper than 90 degrees can cause the Robomower to lose track of the perimeter
wire. In situations where a corner may require a wire placement of less than a 90-degree angle,
placement can be adjusted using several angles to avoid this. See Figure 1.4.

1.5 Narrow Areas And Narrow Passes
The minimum distance for an effective narrow pass is 5.5 feet (1.7 m) between perimeter wires.
Figure 1.8.
1.6 Defining Obstacles-Perimeter Islands
Many obstacles can be left in the lawn without consideration to excluding them using the
perimeter wire. The basic rule of thumb is that the obstacle must be at least 6 inches (15 cm)
high from the ground and the obstacle must be relatively rigid. Good examples of these kinds of
obstacles include many trees, phone poles, power poles and flag poles.
To create a perimeter island, take the wire from the perimeter section closest to the obstacle and
peg the wire around the obstacle, returning back to the same spot of the perimeter. There are
two keys to setting up the perimeter wire to exclude an obstacle; 1) the two wires going to and
from the obstacle should be placed under the same peg (touching) and 2) follow the direction of
set up as shown in Figure 1.6.

The Robomower can freely move across this section, but will still
recognize the perimeter island. By allowing this, multiple
obstacles in a given lawn will have little effect on free movement of
the Robomower or its’ efficiency.
Large trees, OK to be treated as an
obstacle and not excluded with the
perimeter wire. Be sure they are at
least 4 feet (1.2m) from the perimeter.

1.7 Multiple Zones/Areas
As mentioned earlier, your home may require more than one zone to be set up in order for the
Robomower to work in all of your lawn effectively Where grass areas are not contiguous, or are
separated by fences or other objects, it is also recommended to make each of these a separate
zone.
Perimeter switch can be moved between different zones or you
can use one switch for each zone.

1.8 Slopes
The maximum slope limit is 15 degrees. If you are unsure as too whether a slope is too steep or
not, attempt driving the Robomower manually up the slope. If the front of the mower does not lift
from the ground, the slope is fine to include in the cutting area. If however it does lift, exclude
this section from the cutting area.
WARNING!
!
Severe injury can occur. When attempting to mow sloped
areas that are too steep for automatic operation of the
Robomower, insure that you can maintain a safe and sure
footing before attempting to mow. Cut across slopes for
safety. Always wear appropriate closed toe shoes when
operating the Robomower manually.

1.9 Completing The Setup
Once the perimeter wire is completed and pegged to the ground, the last step to complete is
attaching the Perimeter Switch to the perimeter wires and testing the setup. Figure 1.12
Note that the wires are adjacent and touching leading from the
perimeter to the Perimeter Switch. Peg firmly to the ground leading
away from the perimeter and towards the switch location

2.3 Setting The Cutting Height And Ground Clearance
Remove the Power Pack before making any adjustments. The Robomower has two basic
adjustments, cutting height and ground clearance. The cutting height adjustment is located at the
front wheel and is controlled by rotating the front wheel hub in or out, which effectively causes the
front wheel to be raised or lowered. See Figure 2.6.
Rotate the front wheel
hub in (lower) or out
(higher) to adjust the
cutting height. Each
click represents about
1/4 inch (6 mm) in
height of cut.

WARNING!
!
Severe injury is possible. Always remove the Power Pack when attempting
to adjust the height of cut or otherwise lifting the mower off the ground.
Never lift the mower or attempt to adjust the cutting height during
operation. Blades are very sharp and severe cuts or lacerations are
possible. When working around or near the blades always wear heavy
gloves.
The ground height adjustment is located in the Power Pack compartment of the mower. See
Figure 2.7. It has two positions, upper and lower. (RL550 Europe has three; upper, lower and
middle) The lower position (closest to the bottom of the Power Pack compartment) provides the
highest level of ground clearance while the upper position (farthest from the bottom of the Power
Pack compartment) provides the least amount of ground clearance. See Figure 2.8.

Remove the Manual Controller
Drive the Robomower to a flat and level section of the lawn, at least 4 feet (1.2 m) from
the perimeter wire
Insert the Manual Controller in the holder and pivot it down flush
Turn on the Perimeter Switch
Follow the calibration setup process as shown in Figure 2.10. (next page)
Note: If the calibration was not successful, the display will read ‘Restart Elsewhere’. Drive
the Robomower to another flat and level surface within the lawn, at least 10-15 feet (3 – 4.5
M) from the first spot and repeat the calibration process as outlined above.
2.5 Testing Wire Position for Edge Mowing
As mentioned in Chapter 1, it is best to test the position of the perimeter wire on edge mowing to
determine if any small adjustments need to be made to the wire position before driving the rest of
the wire pegs into place. Remove the Manual Controller from the holder and follow the steps in
Figure 2.9 to turn off the mowing blades for this test. Repeat this process to turn the blades back
on once you have completed this test.

The Robomower cannot operate unless the Perimeter Switch is turned on and the mower is on
the inside of the active perimeter. Press the ‘ON’ button to turn on the switch. You will hear one
short beep when the switch is first pressed, indicating it is on. If one of the other indicators is on
refer to Chapter 7, Text Messages and Troubleshooting for further help.
WARNING!
!
Serious injury or death can occur. This machine has sharp
rotating blades. When operating in automatic mode, keep
children, pets and bystanders away from mower. When
operating automatically, do not leave unattended if children,
pets or other persons will come in contact with the mower
during operation. Never allow persons or pets to ride on this
machine or block the path of travel.
3.2 Positioning The Robomower On The Lawn
Remove the Manual Controller from its’ holder and drive the Robomower into the lawn area to be
cut. Position the Robomower at least 3 feet (1 m) from any straight length of perimeter wire, with
the front of the mower pointing to the perimeter wire. Figure 3.1.

Chapter 3
Page 22
3.4 Scanning (Mowing)
Keep in mind that the Robomower will not mow all the grass on its first pass, in fact it will leave
uncut grass in between many of the legs it makes. This is expected and is entirely normal.
These uncut areas will be cut on subsequent passes of the Robomower across the lawn. Just
like a dishwasher, wait until the job is finished before you can appreciate the results. The
Robomower will continue to run for the amount of time selected or for the default ‘MAX’ time,
which is generally 2.5 to 3.5 hours, depending on grass type and condition. (RL550 Europe 2
hours) See Chapter 6, Operator Settings and Advanced Features for more detail on setting
operating time.
Note: There is an option to skip the edge mowing and to start scanning (mowing) the main area
of the lawn. Simply press the ‘GO’ button two times in sequence when starting the mower.
3.5 Mowing Complete
When the Robomower has operated the allotted time, it will simply stop in the lawn, waiting for
you to drive it back home and plug it into the charger, ready for the next mowing session. The
LCD will display a text message as seen in Figure 3.7 if the mowing time is set to the default time
of ‘MAX’ or the message as shown in Figure 3.8 if the mowing time has been selected to any
time other than ‘MAX’.
Recharge Battery

Time Completed
Figure 3.8
If the Robomower has completed its’ mowing and it is more than 20 minutes before you arrive to
move it, the LCD screen will be blank. The Robomower will shut itself down into a sleep mode
after 20 minutes of inactivity at all times. This is an energy saving feature. Pressing the ‘GO’
button or removing the Manual Controller from the holder will ‘wake up’ the Robomower and
display the message that was on the LCD when it went into sleep mode. In this case, either the
message in Figure 3.7 or 3.8.

Power Pack Charging
&
Power Management
4.1 Charging
The standard charger (power supply) included with your Robomower will re-charge the Power
Pack from the ‘Recharge Battery’ level in approximately 24 hours, depending on conditions.
Figure 4.1 There is a fast charger available as an accessory. See the accessories available for
your Robomower in Chapter 10.
Connect the output lead of the charger, Figure 4.2, into the charging socket, located under the
Manual Controller holder, Figure 4.3.
Connect the other end of the charger to a regular
household receptacle, 120 Volts AC and the charging process will begin (European models utilize
230 volts mains power). Lightly pivot the Manual Controller down, allowing it to rest gently on the
charging cord. DO NOT attempt to force the Manual Controller all the way to the flush position.
The Robomower charger is designed for indoor dry use only. Do not charge the Robomower
where wet contact is likely. The LCD on the Manual Controller will display the text seen in Figure
4.4 and the battery icon will continually move from empty to full to show the charging. Once the
battery is fully charged, the message will change to that as shown in Figure 4.5, reminding you to
keep it connected to the charger until the next use.
Charging is such an important aspect for assuring good performance and Power Pack life that a
special alert and power management system is incorporated into the mower to remind and alert
you when the proper charging process is not occurring.
WARNING!
!
Shock hazard. Injury or electrocution can occur. The Robomower
charger is designed for indoor use in dry locations only. Never use
the charger or charge the Robomower in areas where extreme
dampness or wet contact is likely. Never use a charger when the
leads are damaged. Use only the recommended charger with your
Robomower.

The importance of proper charging and maintenance of the
Robomower Power Pack cannot be stressed enough. Failure
to follow the recommended charging procedures will result in
poor performance of the Robomower and shorten the life of
the Power Pack.
4.3 Off-season storage
The Power Pack is best to stay connected to the charger at all times of non-use. The charging
system is designed to operate continuously without a problem and will not damage the Power
Pack. The only exception to this rule concerns extremely cold temperatures. If you store your
Robomower in an area where the temperatures can reach –4F (-20 C) then follow these steps;
1) fully charge the Power Pack for each Robomower you own
2) store them in a dry area where the temperature will not fall below 0 degrees F (-18 C).
The Robomower should always
be connected to the charger
when not in operation

Manual Operation
5.1 Driving and Navigating
The Robomower is equipped with a Manual Controller that allows you to easily drive it. Using
your thumb or index finger of your right hand, gently press the navigator button in the direction
you want to drive. The button is omni-directional, allowing for slight turns as well as sharp turns,
all the way to a complete circle.
WARNING!
!
Serious injury can occur. Always wear appropriate footwear when driving
and using the Robomower in the manual mode. Keep a safe distance from
the mower when operating it manually. Note that the reverse driving
direction is from the point of view standing at the rear of the mower. Always
look behind you when using the reverse direction drive. Do not operate the
mower in areas not suitable for manual operation or on slopes where a sure
footing is not possible. Cut across slopes for safety. Do not drive the
mower with persons sitting on it and do not manually operate within 10 feet
(3 m) of other persons or pets.
5.2 Manual Mowing
You have the ability to manually activate the blades on the Robomower in order to trim small
areas. After the blades are activated you may drive the mower using the navigator button and
you may cut in any direction the navigator button will operate. The manual mowing operation on
the Manual Controller is a two-step OPC (Operator Presence Control) type system for safe use.
At any time the blades have been stopped, it will require the OPC activation process to be
repeated. During manual mowing operation, activation to any bumper sensor will shut down the
blades, requiring the blade activation process to be repeated.
Step 1
Using right thumb, press and hold
‘C’ button
Step 2
While holding the ‘C’ button,
press the ‘Mow’ button with
your left thumb. The blades
will now start.
Step 3
Release the ‘C’ button. Maintain
pressure on the ‘Mow’ button with your
left thumb. Navigate and drive the
mower using your right thumb on the
‘Navigator’ pad.

Text Messages and Troubleshooting
7.1 Messaging
The Robomower is equipped with a sophisticated monitoring system that will notify you in the
form of a text message in the LCD panel when common operational faults occur. In addition, it
will also communicate in text form several messages that are meant as a prompt to the user to
perform a certain function or action. In the event the Robomower has not completed an
anticipated operation and has stopped in the lawn, it will typically display a text message
informing you of the reason it has stopped. If the LCD screen is blank, pressing the ‘GO’ button
one time will wake the mower up and the last fault or message displayed prior to stopping will
now be displayed.
While it is impossible to list every circumstance that will result in a message display, the most
common reasons for a particular message are provided in the following chart. Following this

Care and Maintenance
9.1 Mowing Deck
The underside of the mowing deck needs to be inspected, and cleaned if necessary, between
operations. The Robomower is a dedicated mulching mower and because of this can accumulate
clippings under the mowing deck, particularly when mowing wet and damp grass. Figure 9.2
WARNING!
!
Serious injury can occur. Always remove Power Pack before lifting
mower. Blades are very sharp and can cause severe cuts or lacerations.
Always wear heavy work gloves when working in and around the blades.
Never use a damaged or broken blade. Use only sharp blades.
Most grass accumulation can be removed using a small wooden stick or similar object. Carefully
scrape the collected grass debris from under the mowing deck. If necessary, remove the blades
to gain better access to the mowing chambers in order to clean them. Do not place the mower
upside down, damage to the Manual Controller can occur. Instead, lean the mower against
another surface to gain access to the mowing deck area.
NEVER use a water hose or other type of liquid sprayer to clean the underside of the mower.
Component damage can occur. Use only a damp or wet cloth to wipe the surface clean after
scraping.
9.2 Blades
The cutting blades of the Robomower should be examined for damage between operations.
Replace any damaged blade found. Only use sharp blades. Replace blades at least once per
season, more often if they have been severely dulled. Machine sharpening is not recommended,
as a good balance cannot be achieved after machine sharpening. See Figure 9.1.
9.3 Outer Housing
Use only a damp cloth and a dry brush to clean the outer surfaces of the Robomower. A light
detergent can be used in a water solution, then soaking and wringing dry the cloth for cleaning.
Never use harsh or abrasive cleaning solutions. Never spray with a garden hose or other type of
liquid spray hose.
9.4 Power Pack
Always follow the maintenance and charging instructions found in Chapter 4 for the Power Pack.
