EPSON ROBOT SYSTEMS —
TO SPEED UP
YOUR PRODUCTION RUN
Our robots palletise, saw, mill, drill, grind, mount, move and assemble. They work
precisely and at breathtaking speed in these and many other applications — often
up to 24 hours a day.
As one of the pioneers in robotics we know exactly what the main feature of the combination of kinematics and intelligent control must be apart from speed and precision: Reliability! That is because the standstill of an installation
resulting in a loss of production is expensive, very expensive. Therefore to us, innovation means more than just
up-to-date robot technology. Every day, our development engineers strive to make our robot systems even more
economical, flexible and reliable — under all conditions.
Integrated automation
We offer you a flexibly expandable range of products with different integrated components. Among these are a
great number of SCARA robots and 6-axis robots for diverse applications as well as controllers and software.
Everything engages perfectly and is easy to operate.
SERVICE AND SUPPORT
Our service and support program helps you to tap the full potential of your Epson robot systems.
Feasibility studies
Pre-sales support
After-sales support
Instead of theoretical simulations
we offer cycle time tests with real
robots. There are many ways in
which you benefit from those studies. Prior to your investment you are
provided with optimal robot configuration and installation site as well as
precise cycle times. That is how you
get maximum planning and project
security.
How can a robot system be efficiently integrated into an installation?
How can cycle times be optimised?
How can the robot program be integrated into external software? Our
application engineers advise you
during planning as well as during
implementation.
Hotline service, repair service on
site, inspection and individual
maintenance concepts as well as
spare part packages tailored to your
needs are only some examples of
how we do everything to have your
production running non-stop.
Central spare part stocking
Training
Whether you need introductory
seminars, or programming, maintenance or operator trainings — our
experts share their knowledge with
you and your employees.
All spare parts are rapidly delivered
from our central warehouse in
Meerbusch, Germany.

WE ARE SCARA!
SCARA (Selective Compliance Assembly Robot Arm) robots, also referred to as
“horizontal articulated arm robots”, are a success story of automation. With four
degrees of freedom, they can freely position and join a payload with every possible
horizontal orientation. They are relatively easy to set up and work particularly
precisely and reliably.
In the beginning was Epson
The SCARA principle: simply reliable
In a study, Professor Hiroshi Makino from Yamanashi
University in Tokyo found that the majority of joining
processes in production are vertical processes executed
from above — that was when the SCARA was born!
The Seiko Epson company immediately took on that
method and developed a robot type for in-house
production. That was even before that kinematics was
brought on the market as the first freely available SCARA
in 1982.
The design of SCARA robots is similar to a human arm,
since they have an articulated arm which can only swing
horizontally. Usually, they have four freely programmable
axes allowing handling in plane-parallel surfaces. The
shaft serves to install tools and can rotate independently
from its vertical motion to freely orientate the product
within the work envelope. Thanks to their design,
SCARAs feature high vertical rigidity.
Adapt your installation to the robot?
Why not just choose the Epson robot you need?

Good — better — Epson
Experience, expertise, inventiveness
or, put more simply: the specialists
Ever since we started, we have been continuously
further developing the SCARA technology and have
realised milestones such as ball screw splines, brushless motors with absolute encoder, Smart Motion
Control and much more. Today, Epson has the most
comprehensive SCARA robot product range worldwide
— offering more than 200 variants.
With Epson you can be sure. We develop SCARA
robots in our in-house research centres and produce
them in our quality-certified manufacturing facilities.
The result: SCARAs that work with perfect precision
and reliability, convince through short cycle times and
are incredibly user-friendly.

COMPACT, FAST,
PRECISE — AND
EXTREMELY VERSATILE
There are more than 200 SCARA variants, arm lengths ranging from 175 mm to
1,000 mm, payloads ranging from 1 kg to 20 kg and different mounting options.
The robots are available in different protection classes or as cleanroom versions —
we are absolutely certain that we can offer you just the right SCARA robot for
your application.
Robust design
The reduced number of assemblies as well as the integrated
feed-through allow reliable operation without expensive
maintenance work.
Small interference contours reduce the risk of collision, which
is particularly important if there are several robots working
together in most confined spaces. High arm rigidities make the
Epson SCARA insensitive to high insertion forces.

G FOR GENIUS —
THE EPSON G-SERIES
Epson SCARA G1
Our mini — compact power
The solution for tasks in most confined spaces: the Epson G1 — developed
as a micromanipulator, transfer unit or high-performance feeder for larger
robots. Designed for work where a thousandth of a millimetre matters, such
as for electronic manufacturing or precision-mechanical work processes.
Ultralight due to its high-strength aluminium design and at the same time
compact and powerful.

Epson SCARA G3
It’s all about the curve
SCARA G3 are just the right choice for use in confined spaces as they are
common in automated component manufacture, since these robots,
despite their compact size, cover a large work envelope.
However, we did not stop there and have further developed the G3
based on the fact that a high percentage of all assembly work is performed
in the same arm orientation. Therefore, Epson G3 are also available
with a left-curved or right-curved first arm. Thanks to this arm geometry
especially developed by Epson, the Epson G3-351-L/G3-351-R is the
only SCARA of that size on the market whose maximum rectangular work
envelope covers an area larger than an ISO A4 sheet.

A comparison of the G3-351S with the lefty arm

square work envelope can be increased by
about 40 %. That is just the space productivity
needed in modern automation.

Epson SCARA G6
The new efficiency class
The new G6 design allows for a large work envelope at very compact
dimensions. The robots can carry out tasks with an arm length of e. g. 550 mm
when usually 600 mm would be required. G6 are the ideal solution for
applications with a focus on high speed at maximum precision, such as is
the case with the production of mechanical and electrical parts, pick-andplace applications, equipping with small parts, dosing or feeding.

Epson SCARA G10
Fast and strong
Ultrafast speed and higher payload? A combination that Epson G10 can
perfectly handle due to the high arm rigidity. G10 are fast in every sense of
the word — for assembly and configuration as well as for handling with
multi-grippers. They use all their advantages particularly in applications
such as the assembly of heavy parts, packaging and palletising as well as
loading and unloading. Since there are no tubes, the design is very compact.

Max. payload: 10 kg
Reach: 650/850 mm
Z-stroke: 180/420 mm
Epson SCARA G20
Long arm with high strength
Manipulators of the G20 series are suitable for high payloads such as heavy
parts or packaging units (up to 20 kg). Since the arm of the G20 is
1,000 mm or 850 mm long, the work envelope is large. Due to the high
moment of inertia of the U joint, heavy loads can be handled fast and
reliably — without any vibration of the robot arm as is the case for many
competition models with a similar arm length.

SOLUTIONS WITH SYSTEM
— AND FUTURE
Epson SCARA robots prove their strong performance and unparalleled reliability
in diverse applications.
Loading and unloading machines
Packaging and palletising
Expectations are high: With high point accuracy, the
robot must still move at high speed to achieve the
required installation throughput. During loading and
unloading, the work pieces are defined on pallets, work
carriers or conveyors or they are fed to the installation
as bulk material with subsequent separation and
passed on after the process. Epson SCARAs carry out
these tasks precisely and reliably in pace with the
machine cycle.
Modern packagings require a high degree of flexibility
of the packaging lines. That is because ever shorter
product change times as well as a high process
reliability must be ensured. Epson robots package and
palletise even highly sensitive parts. With Conveyor
Tracking, the robots can also be used for picking up
parts from moving conveyors or placing them there.
In that process, objects are detected by a camera or
sensor.
Assembling and equipping
Testing, measuring and checking
Manual activities during assembling and equipping are
inefficient as well as error-prone. Apart from that,
the human arm is naturally limited in its range of motion.
Thanks to the optimised ratio of arm 1 and arm 2,
Epson SCARAs, on the contrary, have maximum freedom of movement and are able to precisely assemble
even the smallest parts. Due to their excellent dynamics,
high insertion forces and rigidities as well as the good
deadload–payload ratio, Epson robots are perfectly
suitable for assembly and equipping tasks — even for
small batch sizes.
Quality checks, measurements, test runs prior to series
production — precise detection is most important here.
Epson SCARA robots with the integrated Epson vision
system handle these tasks also at high clock rates. The
PC-based Epson RC620 master controller allows use
with other software and hardware for measuring and
checking. Moreover, the master controller can be easily
combined with pattern recognition systems or forcetorque sensors from other manufacturers. If the product
deviates from the tolerance values with respect to the
predefined parameters, it is detected as faulty at an early
stage and safely sorted out.
SO THAT YOU KNOW
BEFOREHAND WHAT YOU
WILL NEED LATER
Trial & error — why not? Before using an Epson SCARA robot in your application,
you can try, compare and visualise sequences at no risk. Not only in the design
phase, but also during integration and operation does the free Epson RC+ Simulator help you save time and money.
The design phase — easy planning and cost reduction
Already during the design phase, you can accurately plan your robot cell
quickly and easily and reliably estimate the cycle time for your application.
This way, feasibility is proven before a single part of the installation is
manufactured. You can also prepare for later installation expansions in the
simulation so that the installation must only be shut down when it cannot
be avoided.
The integration phase —
reducing integration times, avoiding damage
Prior to the robot delivery, an offline program validation is carried out.
Programs can be created parallelly and even complex motion sequences
can be visualised and evaluated. This serves to detect risks of collision
and avoid damage to the equipment.
The Epson RC+ development
environment — powerful,
efficient, intuitive
With its intuitive Windows operator
interface, the open structure and
integrated Machine Vision, the
powerful Epson RC+ project management and development environment is ideal for the uncomplicated
programming of your applications.
Now, we have also added a graphical 3-D environment to allow you to
almost entirely simulate the robot
program and obtain visualised robot
motion.
The operation and maintenance phase —
reduction of downtimes
Troubleshooting and program modifications can be comfortably carried
out from your office. Collision detection, reachability checks and robot
motion are visualised in 3-D.
SCARA, 6-axis or the Epson SPIDER — all of
these robots as well as different motion
sequences can be imaged with the Epson RC+
Simulator.

BECAUSE QUALITY IS THE
BEST RECIPE
Just like all other Epson robot systems, robots of the
Epson SCARA G-series also feature a great number
of advantages. High-quality components ensure longevity and high availability. The design also focuses
on reliability — starting from well-established design
principles to easy accessibility of all components.
The economical and futureoriented complete solution
All main components are Epson
products; they are developed in our
research centres and produced in
our quality-certified manufacturing
facilities. Hardware and software
match perfectly.
We get to the point fast: Smart Motion
Smart Motion is the revolutionary motor management by Epson used in all
Epson robot systems. At low vibration, Epson robots reach the end position
much faster and much more precisely. Optimum positioning, short cycle
times and increased path accuracy — be on the economical side with
Smart Motion!

As a result of overshooting, common motor controllers lead to increased deviations.
The result: imprecise positioning, poor interpolation and longer process times. Epson Smart Motion,
however, minimises overshooting. Epson robots are more precise and product-conserving and get
to the point faster — even if cycle times are extreme.
FLEXIBLE
CONTROLLER
CONCEPT
EPSON SCARA G-SERIES
A central controller or compact slave controller —
Epson SCARA G-series robots can be perfectly
controlled by means of Epson controllers and can be
smoothly integrated into your production processes.
Epson RC180 — the most compact, most lightweight and
fastest controller of its performance class on the market
With its compact dimensions, the Epson RC180 is incredibly small.
The controller is mainly intended to work as a stand-alone slave.
Epson RC620 — the powerful master controller for up to
20 axes
Epson Vision
Epson Vision allows high-speed communication
between robot and Machine Vision. Bar codes
are identified, and so are characters and icons —
even if backgrounds are changing or clock rates
are high.
This controller has it all under control: robots, conveyors and many other
peripherals. Due to its open, Windows-based system design, the controller
offers unlimited possibilities and allows easy operation. The RC620 supports
Conveyor Tracking as well as most diverse bus protocols and interface
expansions.
For even higher demands of system resources, such as fieldbus masters or
the integration of external .dll files, there is the Epson RC620+. It features a
higher-performance processor and an even greater memory expansion.
For robots with eye contact
The powerful, integrated vision systems reliably detect and position parts —
even in case of manufacturing deviations, part changes or varying light
conditions. Epson Machine Vision: That is perfectly matching hardware
and software.

Reduced mass but increased power. Optimised efficiency. Compact design but
a larger work envelope. We always consider the next step. It is not all about the
initial investment, but also about the operating and follow-up costs of our robots
in your application. Our aim: to be efficient in every way.
More power in reduced space
Slim design and minimised weight lead to considerable savings in operating
costs. Compared to previous models, we have reduced our G-series by
10% in height, for example. Since the robots have no tubes and the user
wiring inside, the design is particularly compact.
Larger work envelope
Economical —
also in the long run
The combination of maximum
reliability, a reduced number of
components and reusability
of components results in a
high added value.
We have increased the working range of our SCARA kinematics by an
average 23 %. The result is an work envelope which is equal to that of
non-Epson robots of the next bigger size.
Higher speed
We have achieved an average increase in axis speed of 20%, just the same
as the payload. Every kinematics has the highest position accuracy of its
class.
High efficiency, optimised ratio of supplied energy and
payload
All Epson robots stand out for a particularly low power consumption.
That way, electric energy is converted into kinetic energy so as
to achieve high efficiency and short cycle times.

THE GREEN WAY:
ENVIRONMENT AND
SUSTAINABILITY
Environmental protection has a long tradition at Epson and is an integral part of
the company philosophy. It is our aim to reduce the environmental impact of our
products — from the concept to recycling, from the choice of materials and
components to transport to reuse.
Saving energy — and costs
Life cycle assessment
Energy is money and a real economic factor. Therefore, we consistently
strive to develop particularly reliable, failsafe products which consume less
and less energy. Since 1995, Epson has implemented an environmental
management system based on a holistic approach.
Since the year 2000, we have been
registering the environmental impact
of individual items of our manufacturing program. Life cycle assessment gives information about how
much raw material and energy a
product consumes within the course
of its production, use and disposal
and what emissions are generated.
Environmental Vision 2050 — our goals
With our Environmental Vision 2050, we set an example. One of our main
intentions is to reduce our CO2 emissions during the complete life cycle of
a product by 90% by 2050. Moreover, we are going to introduce reuse and
recycling for all of our products and are engaged in protecting biodiversity.
Sustainable and environmentally friendly
Within the framework of our sustainability initiative, we have committed
ourselves to high ethical and ecological standards. The annual “Epson
Sustainability Report” documents how we ensure and continuously improve
the good environmental performance of our products and production
processes.
