Industrial robotics is the use of programmable, physically embodied machines to perform repetitive or precise manufacturing tasks—such as pick-and-place, assembly, dispensing, and inspection—inside a production environment. It fits into factory automation as the "hands" layer: where factory automation coordinates the whole line and RPA (robotic process automation) handles software-only tasks like data entry, industrial robots do the physical work. Consider it when a task is high-volume, repeatable, and demands consistency or speed beyond reliable manual output.

Industrial robotics vs. general robotics vs. RPA

These three terms get used interchangeably, but they solve different problems.

The practical distinction: industrial robots are fixed or semi-fixed machines engineered for repeatability and cycle-time targets. RPA never touches a physical product. If your bottleneck is a physical step on the line, you are looking at industrial robotics, not RPA.

Factory tasks that commonly justify an industrial robot

Industrial robots tend to earn their place where a task is repetitive, precision-sensitive, or physically demanding. Common categories:

• Pick-and-place / machine tending — loading and unloading parts from presses, CNC machines, or test stations.
• Assembly — inserting, fastening, or joining components with consistent force and position.
• Dispensing — applying adhesives, sealants, or solder in repeatable patterns.
• Inspection and handling — moving parts through vision or measurement stations.
• Packaging and palletizing — end-of-line tasks with high repetition.

As Epson's own positioning puts it, manufacturers adopt industrial robots to reduce production costs, improve product quality, and increase their bottom line. Those three outcomes map directly onto the task types above: cost comes from labor and cycle-time reduction, quality from repeatability, and throughput from running without fatigue.

Matching a robot type to the task

The right robot depends on reach, payload, precision, and how the task is laid out.

• SCARA robots — fast, horizontal reach, good for pick-and-place and assembly where the motion is mostly in a plane. A strong default for small-part handling.
• 6-axis articulated robots — flexible positioning in 3D space; suited to complex assembly, machine tending, and tasks needing varied orientation.
• Cartesian / linear robots — simple, rigid motion along axes; good for dispensing, inspection, and tasks with a fixed path.
• Delta robots — very high speed for light payloads; common in high-throughput pick-and-place.

A simple matching rule: start with the motion the task actually requires. If parts move in a plane at high speed, SCARA or delta usually fits. If the tool must approach from many angles, a 6-axis arm is the safer choice. If the path is fixed and simple, a Cartesian system may be the most cost-effective.

Benefits and the constraints that come with them

The benefits are well established in the category: lower production cost, more consistent product quality, and higher throughput. But each benefit carries a constraint you should plan for.

• Integration — a robot is one component. It needs end-of-arm tooling, fixturing, a controller, and often vision or sensors. Budget for integration, not just the arm.
• Safety — robots operate at speeds and forces that require guarding, risk assessment, and compliance with applicable safety standards. This is a design requirement, not an add-on.
• Cost — total cost includes the robot, tooling, integration, programming, and ongoing maintenance. The payback case depends on volume and labor cost, so model it against your actual task.
• Flexibility limits — a robot programmed for one task may need re-tooling and re-programming for another. High-mix, low-volume work needs more flexibility than a fixed automation cell provides.

How to decide whether to apply it

Work through these questions before committing:

1. Is the task repetitive and high-volume enough? Robots amortize best over sustained production.
2. Is the task physically hard to do consistently by hand? Precision, force, or speed requirements favor automation.
3. Can the task be described as a repeatable motion? If it varies every cycle, automation is harder to justify.
4. Have you accounted for integration, safety, and tooling? These often exceed the robot's own cost.
5. Does the payback work at your volume? Compare total cost against labor, scrap, and throughput gains.

If most answers point toward repetition, precision, and volume, industrial robotics is a reasonable fit. If the task is low-volume, highly variable, or mostly software-based, look at RPA or general automation instead.

For a direct comparison of Epson industrial robots against other automation options for a specific factory task, the choice comes down to the same dimensions: task motion, payload, precision, integration effort, and total cost.

FANUC robots are industrial robotic arms and collaborative robots made by FANUC, a company whose global site also covers FA (factory automation), ROBOMACHINE, CNC, ROBODRILL, ROBOSHOT, ROBOCUT, ROBONANO, and laser products. They are used to automate tasks such as welding, picking, palletizing, machine tending, and assembly, and they integrate with FANUC controllers, vision, and CNC/FA equipment. This guide explains the main robot series, what each is typically used for, and how to think about selecting one.

Where FANUC robots fit in factory automation

FANUC organizes its business around factory automation and robotics. Robots are one part of that picture, alongside CNC systems and ROBOMACHINE products (ROBODRILL, ROBOSHOT, ROBOCUT, ROBONANO) and laser equipment. In practice, a FANUC robot is usually not a standalone purchase: it works with a controller, and often with vision and other FA equipment, to form a cell or production line.

This matters when you evaluate a robot, because the arm alone does not determine whether a task is feasible. The controller, the end-of-effector, the vision setup, and how the cell connects to existing CNC or FA equipment all affect the result.

Major FANUC robot series

FANUC's robot range is commonly grouped into several families. The exact payload and reach figures vary by model, so treat the descriptions below as orientation and confirm specifications for the specific model you are considering.

Two practical distinctions cut across these families:

• Industrial robots vs. collaborative robots. Traditional industrial arms (M-, LR Mate, R-) are typically deployed in guarded cells and chosen for speed, payload, and repeatability. CRX cobots are designed for collaborative operation, which changes how they can be installed and used on a line.
• Payload and reach as the first filters. For any series, the two numbers that most often decide whether a model fits are how much it can carry and how far it can reach. A task that needs a long reach to a machine tool, for example, will rule out compact models regardless of series.

Common applications

FANUC robots appear across a recurring set of industrial tasks:

• Welding — arc and other welding processes, often with the robot integrated into a welding cell.
• Picking and handling — moving parts between positions, frequently paired with vision to locate randomly oriented parts.
• Palletizing — stacking cases or goods, typically requiring higher payload and reach.
• Machine tending — loading and unloading CNC machines or ROBOMACHINE equipment such as ROBODRILL.
• Assembly — placing, inserting, and joining components, often with force or vision feedback.

The application usually determines the series more than the other way around. A palletizing task points toward a higher-payload M- series model; a compact machine-tending cell points toward LR Mate or a CRX cobot.

How FANUC robots integrate with controllers, vision, and CNC/FA equipment

A FANUC robot is part of a system. Three integration points come up repeatedly:

1. Controller. The robot is driven by a FANUC controller, which runs the motion programs and manages inputs and outputs to the rest of the cell.
2. Vision. Adding vision lets the robot locate parts rather than rely on fixed positions, which is common in picking and inspection tasks.
3. CNC and FA equipment. In machine tending, the robot communicates with CNC machines or ROBOMACHINE products to coordinate door opening, part exchange, and cycle timing.

Because these elements are interdependent, a realistic evaluation asks not only "which robot" but "which robot plus controller plus vision plus cell layout."

Key factors when selecting a FANUC robot

Use these as a checklist before narrowing to a model:

• Payload. The weight of the part plus the end-effector must be within the robot's rated capacity, with margin.
• Reach and working envelope. Confirm the robot can physically reach every position the task requires, including machine doors and fixtures.
• Application type. Welding, palletizing, assembly, and machine tending each push toward different series.
• Industrial vs. collaborative. Decide whether the cell will be guarded (industrial arm) or needs collaborative operation (CRX).
• Integration requirements. Identify whether vision, CNC communication, or other FA equipment is needed, since this shapes the controller and cell design.
• Environment and duty cycle. Consider the conditions and how continuously the robot will run.
