Industrial robots: what they are, uses, and the future for businesses

Did you know that more than 60% of repetitive industrial tasks can already be automated without human intervention? This is not a future scenario: it is happening now, and companies that still do not take it into account could fall behind. Industrial robots not only transform production lines, but also completely redefine how we think about efficiency, safety, and profitability in manufacturing environments. In this article, you will learn what these systems really are, how they have evolved, what they are used for, and what you should consider if your company is evaluating their adoption. In addition, we explore the trends driving the evolution of this technology.

What is an industrial robot?

An industrial robot is a multifunctional, programmable, automatically controlled manipulator designed to move materials, parts, tools, or specialized devices through variable programmed motions. According to ISO 8373, these systems must have at least three degrees of freedom and be reprogrammable for different tasks.

Unlike service or mobile robots, industrial robots are designed specifically for manufacturing and mass-production environments, where precision, repeatability, and speed are critical.

Brief history and evolution

The first industrial robot was Unimate, installed in 1961 by General Motors. This mechanical arm automated the handling of hot metal parts, marking the beginning of industrial robotics.

In the following decades, robots evolved into more sophisticated systems with up to six axes, sensors, and machine-vision capabilities.

Today, collaborative robotics (cobots) allows humans and robots to safely share a workspace, increasing the flexibility of production lines.

Main applications of industrial robots

Industrial robots are used across a wide range of industries, with the most common being:

• Welding: Welding robots are essential in the automotive and metalworking industries. They perform arc and spot welding with high precision and speed, ensuring consistent joints and reducing the margin of human error. They also minimize risks from heat, sparks, and toxic fumes.
• Material handling: Used to move, sort, or assemble components, these robots automate tasks that require strength and repetition. Their use improves workplace ergonomics, reduces cycle times, and optimizes production flow.
• Palletizing and packaging: They automate product stacking and preparation for distribution. They are common in the food, pharmaceutical, and logistics industries, where packing speed and pallet organization are critical to warehouse efficiency.
• Painting and coatings: They ensure uniform coverage, reducing paint waste and improving finish quality. Their use is common in automotive, home appliances, and metalworking, where high precision and safe conditions for operators are required.
• Quality inspection: Equipped with cameras and machine-vision systems, robots can detect defects imperceptible to the human eye. This helps maintain higher quality standards and reduce costs from defective products or returns.
• Food and pharmaceutical industry: They perform tasks such as packaging, sorting, cutting, or dosing, always meeting strict hygiene standards. They are ideal for handling delicate or sterile products without human contact.

These applications align with the growing need for flexible, scalable automation, offering companies a clear path to improving competitiveness, traceability, and responsiveness to market demand.

Components, autonomy, and safety

An industrial robot is made up of several key components that work in sync:

• Actuators and motors: These are the elements responsible for generating motion. Actuators can be electric, hydraulic, or pneumatic, depending on the required force and the environment. They determine the robot’s precision, speed, and payload capacity.
• Sensors: They collect data from the environment and from the robot itself, including position, temperature, force, or proximity. Thanks to sensors, the robot can adjust its behavior in real time and operate more safely and efficiently.
• Controllers: They function as the system’s “brain.” They interpret programmed or software-generated commands, process sensor information, and execute actions through the actuators. They can be local or connect to industrial networks to synchronize with other machines.
• Programming and monitoring software: It allows you to define paths, sequences, operating parameters, and the robot’s tasks. Modern environments enable intuitive programming, including via graphical interfaces or guided learning.

Levels of autonomy

• Program-controlled robots: They perform repetitive tasks following previously established routines. Their autonomy is low, but they offer high precision and speed in stable environments.
• Adaptive or intelligent robots: They integrate technologies such as artificial intelligence, machine vision, and machine learning. They can recognize objects, adapt to variations in the environment, and optimize their behavior based on real-time data.

This advanced autonomy is essential in processes where flexibility and variability in products or working conditions are high.

Safety in industrial robotics

The safe integration of robots in work environments is a priority. International standards, such as ISO 10218 and ISO/TS 15066 (for cobots), set key requirements such as:

• Safe design of robotic cells: physical or virtual delimitation of the work area.
• Limited speeds in collaborative mode: cobots reduce their movement or stop when humans are nearby.
• Presence sensors and emergency stop: to ensure personnel safety.

In addition, it is increasingly common to implement risk simulations, virtual environments, and digital twins to validate safety conditions before the system is commissioned in real operation.

Trends and the future of industrial robotics

The future of industrial robotics is shaped by:

• Cobots and Industry 4.0: greater human-machine collaboration and integration with IoT and MES systems.
• Generative AI: models such as Gemini or ChatGPT can assist with robot programming and diagnostics.
• Expansion in SMEs: thanks to more affordable prices, modular solutions, and greater ease of use.

Considerations for companies in the research phase

For organizations evaluating the adoption of industrial robots, it is recommended to:

• Assess ROI: considering not only the initial cost, but also long-term savings in labor, quality, and efficiency.
• Analyze scalability: the system must adapt to production increases without major additional investments.
• Plan maintenance: considering the availability of spare parts and technical support.
• Commit to AI integration: systems with vision, learning, or natural language can make operation easier.

Frequently asked questions about industrial robots

1. What is the difference between an industrial robot and a complete robotic cell?

An industrial robot is a multifunctional, programmable manipulator that performs specific tasks such as welding, assembling, or palletizing. By contrast, a robotic cell is a complete system that integrates the robot with additional elements such as conveyors, sensors, or safety systems, operating as an autonomous unit in production.

2. What safety standards should I consider when integrating industrial robots?

It is essential to comply with standards such as ISO 10218, which regulates safety for industrial robots, as well as ISO/TS 15066 for collaborative robots. These standards ensure safe and reliable environments for human-robot interaction.

3. What type of robot is most recommended if my factory has space constraints?

For limited spaces, SCARA or Delta robots are usually the best option. They are compact, fast, and precise, making it possible to automate tasks without requiring large areas or bulky structures.

4. How do I know whether I need a Cartesian robot or an articulated one?

If your operation requires precise movement along linear axes (X, Y, Z), a Cartesian robot is ideal due to its precision and lower cost. However, if you need flexibility, reach, and the ability to handle complex configurations, an articulated robot is more suitable.

5. What advantages does installing collaborative robots offer compared to conventional ones?

Cobots are safer, more flexible, and easier to program, and they are also more affordable for SMEs. They can operate alongside workers without physical barriers, which reduces integration costs and improves return on investment.

6. What phases should the project include if I want to implement an industrial robot in my plant?

A well-structured project should include: initial process assessment, system design with the appropriate robot, installation and programming, safety and performance validation, and a maintenance and staff training plan.

7. Can I monitor the status and performance of my industrial robots in real time?

Yes. Modern robots incorporate advanced sensors that enable real-time data capture. By applying predictive maintenance techniques, it is possible to anticipate failures, optimize operational availability, and reduce downtime costs.
