FANUC produces the largest range of industrial robots in the world, with payloads ranging from 1 to 2,300 kg capacity. Most models are of the
6-axis articulated arm style common in industrial environments but specialty models are also produced with varying axis configurations and application focuses. Some specialty models have fewer or more axes or special characteristics that help them perform in certain environments (such as in clean rooms or in wet/dirty wash down areas).
Robots A typical FANUC robot system comprises a robot arm (also called the
mechanical unit), a controller, and a teach pendant. This equipment comes standard with any FANUC robot and can be customized during the ordering process to suit each application.
Arm The robot arm is what most people think of when they think of a robot: this is the servomotor-articulated machine that performs the work. Robot arms are sold without any attachments, or
end effectors, to perform work. Integrators or end users design or purchase custom end effectors suitable for their application and attach these to the robot's faceplate. Through-arm cable sets allow the robot to pass signals or pressurized air from the base of the robot out to the end effector. Signals carry useful information from end effector sensors back to the robot to, for example, confirm when a part is being held by the robot or is missing. Signals can mean basic IO signals (on/off) or more advanced communication such as Ethernet. The pressurized air is used to actuate grippers or power vacuum cups (through
venturi generators) to grip and move parts.
Controller The controller contains computers that control the arm, power supply and regulation equipment, and sometimes auxiliary hardware specific to an application such as IO or networking equipment. Due to the variety of automation applications being deployed, controllers must contain hardware that enables the robots to be used in many different applications and with other technologies. To that end, all FANUC controllers contain the computers and connections required to use 2D/3D cameras, they can function as
PLCs, and even operate as a web server to allow technicians to remotely access the robot from a browser.
Teach pendant The teach pendant is the robot programmer's primary interface with the robot when teaching and maintaining. During normal operation, the teach pendant is usually stowed out of the way so the robot can automatically run through programmed motion. The teach pendant contains a touch screen display and keypad to view and edit program data, as well as a
deadman switch that the operator must hold in order to enable the robot to move. This allows the programmer to safely operate the robot while being in close proximity to the arm. During normal operation humans are kept away from the robots for safety reasons.
Handling robots Handling robots move goods, perform assembly tasks, and inspect parts. This class is essentially the standard robot offered and is suitable for most general industry applications. Many robots are produced within this class and are grouped into distinct payload groups and arm families. Robot series included in this designation include the LR Mates, M-10, M-20, M-900, M-1000, and M-2000 series.
Collaborative robots FANUC produces a range of industrial robots with safety sensors and software to enable limited power and force collaborative operation. This allows the robots to safely work alongside humans in a collaborative fashion. FANUC's collaborative robot series include the CR-Series and the newer CRX-Series.
Palletizing robots Palletizing applications have no need for 6 axes of articulation common to other industrial robots because boxes are picked, placed, and only rotated along the floor plane. To simplify design and improve rigidity, palletizing robots are produced with 4 axes of articulation. These robots use a "
parallel link" design that keeps the wrist at a fixed orientation that is parallel with the floor. This lets the operator program the robot to pick and place boxes without worrying about keeping the box level with the pallet.
Delta robots These robots are sometimes referred to as "
spider robots" due to the shape and movements of their arms. These are low-payload high-speed robots commonly used to pick or place objects off fast conveyor belts. It's common to see several of these robots arranged along a conveyor belt, all picking or placing objects at high speed. Delta robots use 3 arms, each controlled by a single axis servo motor. The 3 arms connect underneath the robot and support the faceplate, similar to an inverted camera tripod. By adjusting the position of each arm, the faceplate is moved around underneath the robot. Because of the lower mass and fewer moving parts, delta style robots trade reduced payload and reach for increased speed.
Paint robots These robots are suitable for use in paint booths. Automotive painting was the most common early market, but robot painters are reaching other industries due to the hazards facing humans from paint. Painters are explosion-proof and suitable for use in hazardous environments. An
atomizer at the faceplate distributes paint particles towards the painted part.
Toploader robots Toploader robots are mounted to a rail that runs over CNC machines for rapid servicing. Mounting one robot on an overhead rail allows the robot to slide from machine to machine, servicing them as required.
ARC robots ARC robots are intended for welding applications. They normally have hollow faceplates for easy mounting of welding tips and space on the arm for mounting welding equipment. ARC robots are generally adapted from other Handling Robots, with minor modifications that better resist weld splatter.
SCARA Robots SCARA robots are 3 link robots suitable for high speed applications with minimal part rotation and work envelopes. Because they have fewer joints to control, they tend to be more rigid and faster than their 6-axis counterparts. FANUC SCARA robots have special controllers that are more compact and energy efficient than others.
Controllers FANUC produces several controllers, each geared towards a certain size of robot.
R-30iB Plus This is the most common controller and is used on most handling, palletizing, and welding robots.
R-30iB Mate Plus This smaller controller is used on the LR Mate series of handling robots.
Compact Plus This is the smallest controller and is used with SCARA robots. It has many of the same capabilities as the larger controllers, but with smaller
power amplifiers.
R-30iB Mini Plus Used exclusively for CRX-Series robots, this controller is smaller than a Mate and is optimized for use with CRX robots. It is the latest generation controller from FANUC, and was released in 2019.
iRVision iRVision, sometimes stylized "
iRVision" is FANUC's robot vision product. These products encompass 2D and 3D imaging sensors (cameras) and software that allows programmers to incorporate vision into robot tasks. Vision is commonly used to allow robots to locate parts on a surface and pick them. This allows parts to be fed into a work cell flexible (such as on a conveyor or a pallet) and removes the need for precise fixturing. Inspection is another common use for vision, allowing the robot to inspect a part for defects, confirm assembled parts are present, or perform other quality control tasks. Cameras can be fixed in a work cell or mounted to the robot itself. ==See also==
