What Are Articulated Robots Used For?
Articulated robots are the most common robot type.
“Articulated” is a term that represents the way axes and
joints move. Axes and joints are usually designed to contain
movement
within a workspace envelope. When considering these types of robots,
you
can also find models designed to work side by side with people,
using
articulation to operate safely without bumping into people or other
machinery. Scroll to the Collaborative Series to see our articulated
robots designed to be safe to operate in the same workspace as
people.
An articulated robot arm design uses a series of axes, ranging from
3-axis models to 7-axis models. A 6-axis robot is one of the most
adaptable articulated robot configurations. With 6 axes, it can move
forward and back, up and down. It can also yaw, pitch and roll,
resulting in a complex set of movements that can simulate the
motions of
a human arm. This articulated robot advantage allows it to do things
such as grab small items from a shelf and put them on a conveyor.
The
same complexity also makes articulated robots an excellent choice
for
robotic packaging solutions, palletizing and custom applications
such as
deburring robots.
Articulated robot advantages include more degrees of freedom (DOF)
than
other robots, making them more versatile. By integrating an
articulated
robot arm design into a production line, you can increase your
productivity by accelerating speed and improving precision.
You’ll
also improve quality and increase flexibility to quickly accommodate
process changes. Because articulated robot systems are a more common
part of the production and manufacturing process, they have also
become
more affordable, making them a viable option for small and
medium-sized
businesses.
Automotive
assembly robots can include articulated robots that serve as
material joining robots, coating robots and sealing robots. Robots
can
be part of the line and handle tasks independently or can be
collaborative—designed to assist humans in the production
process.
What Are Delta Robots Used For?
Delta
robots are umbrella-shaped robots designed to mimic the
movement
of the hand. This robot is ultra fast, however, so they can operate
with
much more accuracy and speed than people. Also known as
parallel-link
robots or spider robots, delta robots are often an excellent
alternative
to expensive all-in-one automation systems.
In delta robots, the motors are fixed within the frame, ensuring that
mass and resistance stay above the workspace and away from the
ultra-light arms and end-of-arm tooling. Delta robots are usually a
light payload robot with tooling that might include a gripper
finger,
vacuum cup, a gripper arm or another custom application.
Because of their unusual construction, delta robots can move their
arms
with exceptional dexterity within their workspace in the x and y
axes,
but usually with limited movement along the z axis. Their work
envelope
is generally more controlled and limited than an articulated robot
work
envelope. Delta robots will require 4 or more axes to complete a
task as
simple as moving an item from a bin to a box, or as complicated as
grasping pill bottles or moving flat items into a standing position
or
other types of part reorientation.
Delta robots’ exceptional dexterity make them an excellent
choice
when choosing precision assembly robots, a pick and pack robot as
well
as a pick and place robot. These high productivity robots are often
good
choices for robotic packaging solutions. Adding vision technologies
allows this series of robots to complete more intricate tasks such
as
placing irregular food items into boxed compartments, such as
transferring food items into boxes.
Delta robots are also suitable for use in plants with strict health
and
safety regulations. They can be configured to comply with food
manufacturers standards for equipment washdown. Motors can be
isolated
in enclosures to ensure that food or pharmaceutical product is
protected
from potential contaminants such as lubricants, fragments of metal
or
plastic, or dust.
Delta robots are practical choices to perform repetitive tasks
quickly
and consistently. This solution is especially useful when replacing
human activity that causes mental fatigue or repetitive motion
injuries,
such as carpal tunnel syndrome, back pain or tendinitis.
Specialty Robots and Series Applications
Because industrial robots can be configured in ways that offer almost
endless functionality, it helps to sort them in a few working
groups,
called robots by series. Articulated robots and delta robots are two
of
the most popular robots by series. As you’re considering
robotics
for your production or manufacturing facility, there are six
additional
categories of robots by series to explore.
Collaborative Robots
Although lights-out automation is an exciting concept, in many
facilities, robots work alongside humans, taking over the tasks that
are
especially repetitive or dangerous. This allows your team to focus
on
more intelligent or cognitive work. Collaborative
robots, or cobots, in manufacturing are designed to work
side-by-side with people. They use safety stop features instead of
fencing, reducing the robot’s footprint. Some models are built
for
light work, such as small assembly robots, while others are created
to
do the heavy lifting in industries such as automotive, metalworking,
distribution and packaging.
By reducing the strain on employees, this robotic series improves
worksite safety and frees people up to focus on more
technically-oriented tasks. FANUC has more cobot models than any
cobot
manufacturer in the industry, including six models ranging from 4 to
35
kilograms in payload for nearly any manufacturing application.
Palletizing Robots
In almost every industry, finished products must be packed into
pallet
configurations for shipping. Although each sector has different
sizes of
finished products with separate weight requirements and various
shipping
configurations, there is a palletizing robot option for almost every
job.
Palletizing robots are job-specific equipment that serve as a part
transfer robot. These heavy-duty robots are installed in ways that
allow
them to interact with the last stages of the assembly line to grip,
lift, move and arrange payloads to preset configurations.
Material handling robot applications for high payload palletizing
robots
can include payloads up to 2,300 kilograms. FANUC was one of the
first
robot suppliers to develop a series specifically designed for
palletizing and still leads the way in the industry.
Arc Welding Robots
FANUC arc welding robots can be found in many different industries.
They’re highly customizable and can work in very tight or
narrow
spaces. These robots were first used in the automotive sector
welding
seats, axles and other components, taking over some of the
most-dangerous tasks in the industry.
Today’s heavy duty robots are built to withstand the rigors of
welding, so your staff can focus on less-hazardous activities. These
welding robots feature a slim arm and hollow wrist design.
Industrial
arc welding robots can be programmed for laser welding, soldering
and
cutting.
FANUC offers a selection of models that can be customized to meet the
welding demands of your organization. An arc welding robot comes
with a
variety of tools that increases versatility and makes the welding
processes safer. FANUC also offers a series of arc welding cobots
able
to work in the same space with your welding operators.
Top Mount Robots
Top mount robots are designed to be light enough to mount safely over
the
workspace as part of a robotic assembly system, making them a type
of
mobile robot. Top mounts or a gantry robot can allow it to move
above
the manufacturing or production process.
If you’re looking for a heavy payload robot, these lightweight
top
mounts can accommodate payloads of up to 70 kilograms. These 6-axis
machines also provide exceptional versatility, making it easier and
safer to tend to and manage jobs.
Top mount robots also keep down costs on machine tending and handling
duties. These models feature a range of axes and variety of mounting
options.
Paint Robots
Paint
robots bring more consistency and speed to your painting
applications and improve safety in hazardous painting work
environments.These coating robots have a smooth aluminum surface
that
resists contamination and is easy to clean. The aluminum surface
also
keeps paint robots lightweight so that they can run on less power. A
hollow wrist feature allows for tubes to run through the robot,
eliminating the need to run outside hoses.
FANUC’s articulated robot configurations can work with a wide
variety of painting and coating applications. The 6-axis
articulation
allows you to optimize your articulated robot work envelope. Because
we
designed some models to operate in hazardous environments with a
wide
range of reaches, paint robots can eliminate the need to put people
into
situations that are dangerous to their health. All of FANUC’s
painting robots have been designed and built in Rochester Hills,
Michigan, since 1982.
SCARA Series
FANUC’s SCARA robots are fast, precise, easy to use and an
affordable solution to maximize productivity. In addition,
FANUC’s
SCARA robots offer best-in-class speed and performance. These
high-productivity robots are designed to work as part of a robotic
assembly system, for pick and place and as inspection robots in a
variety of applications.
Although SCARA robots are often small assembly robots and may be
considered a light payload robot, depending on the model, they can
also
handle a payload up to 6 kilograms. Because they feature a
pedestal-mount design, they fit into smaller footprints and operate
within an efficient SCARA robot work envelope. This offers exciting
possibilities for a variety of robotic packaging solutions.
