CES 2026, the world’s largest technology trade show, has come to a close—and this year, one theme stood out above all others: robots. From humanoids and quadrupeds to sports and healthcare applications, robotics was everywhere on the show floor, signaling that the era of Physical AI—where AI and robotics come together in the real world—is quickly taking shape.

With Jae-bum Park, Senior Researcher at POSCO Research Institute, we look at what CES 2026 revealed about the future of robotics and where POSCO Group’s strengths could create new opportunities in this fast-growing industry.

Powering the Energy Transition: Robots Were Everywhere at CES 2026

At this year’s CES, robots were impossible to miss. Even in booths hosted by companies not traditionally associated with robotics, robot-related technologies appeared throughout the exhibition. The message was clear: AI-powered robots are moving beyond demonstrations and entering everyday life and industrial environments.

One of the most talked-about exhibits was Atlas, the humanoid robot presented by Boston Dynamics, Hyundai Motor Group’s robotics affiliate. Equipped with 56 degrees of freedom (DoF), Atlas demonstrated highly flexible movement and the ability to handle heavy-duty tasks involving loads of more than 50 kilograms—offering a glimpse of its potential in real industrial settings.

The exhibition also introduced a collaboration case involving POSCO and Boston Dynamics. On screen, Spot, Boston Dynamics’ quadruped robot, was shown moving through high-temperature facilities at a POSCO steelworks. In a noisy and heat-intensive environment, Spot was able to detect gas leaks and carry out precise inspections of equipment and infrastructure. The scene offered a compelling look at how robots are evolving from crowd-pleasing exhibits into reliable co-workers on industrial sites.

Another exhibit that drew attention came from Korean company Bodyfriend, which showcased a massage chair designed to feel almost like wearing a robotic suit. Its wearable AI healthcare robot, with independently moving arms and legs, attracted strong interest for its ability to analyze and stretch the user’s joints.

Robots were also making an impact in sports. Table tennis robots and combat robots once again proved popular with visitors, while sports robots introduced by Chinese companies such as Unitree and others showed just how far the technology has advanced. Some were able to analyze an opponent’s movements and track the trajectory of a ball in real time, providing highly detailed coaching.

Degrees of Freedom: What Makes Robot Movement More Sophisticated

As CES 2026 made clear, robot movement is becoming increasingly refined as technology advances. One term that many robotics companies use when discussing precision and flexibility is DoF, or Degree of Freedom. In simple terms, DoF refers to the number of joint axes a robot can move or control.

Generally speaking, the higher the DoF, the more independently controllable joints a robot has. This is particularly important for humanoid robots, which are expected to move in ways that resemble the human body. Industrial robot arms used in automated manufacturing processes typically have around 6 DoF, while humanoid robots usually range from 30 to 60 DoF. With 56 DoF, Boston Dynamics’ Atlas is close to the level required to mimic full-body human joint movement.

That said, increasing DoF also means adding more components such as motors, reducers, and sensors. In other words, the more sophisticated the movement, the higher the production cost. That is why robotics companies carefully design and allocate DoF based on each robot’s purpose and application.

Why Actuators Matter

An actuator is the drive unit that physically moves a robot’s joints. It can be understood as a complete joint system that combines a motor, reducer, sensor, and control circuit.

A motor on its own produces rotational motion. But for a robot arm to extend in a straight line or bend with precision, rotational movement alone is not enough. By integrating gears and electronic controls, an actuator enables more complex forms of motion, including both rotational and linear movement. If a motor is like a muscle cell, an actuator is the complete muscular joint that allows a limb to move in a controlled way.

For a humanoid robot with 56 DoF, roughly 56 precision actuators are needed.

Why Hyper NO Matters in the Age of Robotics

Electrical steel is also a critical material in motor manufacturing, accounting for roughly 20% to 30% of total motor production cost. This is especially important in robot motors, which must generate high output despite their compact size. In many cases, the performance of the electrical steel used inside the motor directly affects the motor’s overall efficiency and output.

To achieve better performance, the steel sheet must be made as thin as possible. If it is too thick, eddy currents* can form inside the material, causing energy loss in the form of heat.

*Eddy currents are swirling electric currents generated by electromagnetic induction when the magnetic field around a conductor changes rapidly.

POSCO’s high-performance electrical steel, Hyper NO, is designed to maximize magnetic performance even at extremely thin, paper-like thicknesses. The thinner electrical steel becomes, the more difficult it is to manufacture. In fact, only about five to six steelmakers worldwide, including POSCO, are capable of stably mass-producing electrical steel at the Hyper NO level. That makes it a strategic material with high technological barriers to entry—and an increasingly important one in the era of robotics and electrification.

Energy and Materials Will Help Power the Humanoid Robot Era

No matter how advanced a robot’s movement may be, it cannot function properly without enough energy. Today, humanoid robots typically operate continuously for only about two to four hours, making battery technology one of the biggest limiting factors in the industry.

At CES 2026, swappable battery systems emerged as a notable trend aimed at addressing that limitation. Boston Dynamics’ Atlas, for example, is known to operate continuously for around four hours, and it is even equipped with a function that allows it to replace its own battery when power runs low.

Tesla CEO Elon Musk recently predicted that there could be 10 billion humanoid robots within 25 years. If production reaches that scale, demand for actuators would rise into the hundreds of billions, making growth in demand for high-performance electrical steel almost inevitable. Once replacement demand is taken into account, the number of batteries required could also reach into the tens of billions.

This would also drive a sharp increase in demand for lithium, one of the key raw materials used in batteries. From this perspective, POSCO Group’s high-performance electrical steel technology and lithium assets are likely to draw growing attention as the robotics market continues to expand.

As robotics moves closer to real-world adoption, the future of the industry will depend not only on software and AI, but also on the materials and energy technologies that make advanced movement possible. In that future, POSCO Group is well positioned to play an important role.

The Asia Pacific region’s Available Seat Kilometers (ASK) has increased 7.9 percent YoY, as China leads the way with numerous airport construction projects. Current and anticipated expenditure on airport infrastructure is USD 391 billion for the entire region.  European airports experienced a 30 percent increase in passenger volume from 2012 to 2017. Currently, there are 450 airports facing a capacity crunch in Europe, and the region is currently expecting to spend USD 123 billion on airport infrastructure. North America saw a 4.9 percent YoY growth in its ASK and is currently and expected to spend about USD 123 billion in upgrading its existing airport infrastructure.

There’s no set formula to deal with the growing capacity crunch, and airports in different regions are finding their own solutions from high tech to high-quality materials.

Speeding up passenger flow

Developing countries rich in land and capital, such as China, will deal with the growing number of passengers by building more airports. In other places such as North America, the focus will be on upgrading existing infrastructure and improving passenger flow with the help of technology.

One example of software that is being applied to speed up the flyer’s journey and minimize errors is biometric technology. In Changi Airport Terminal 4, a system called Fast and Seamless Travel (FAST) with biometric technology and self-service features is already in place and will begin operations at the end of October.

Passengers will be able to check-in, check baggage and board the plane, all through a series of self-service stops equipped with fingerprint scanners and facial recognition for identification instead of passports and boarding passes. Sydney Airport will also have a similar system running by the second half of 2018, and many major airports are looking to expand biometric technology applications to other areas such as flight information display systems and on-flight payments.

This is great news for crowded airports. Besides bad weather, the biggest reason for delayed flights is delayed passenger information. As of now, airlines and airports do not share data regarding passengers. Even though airports are aware of passenger check-ins hours before departure, airlines are only notified at boarding gates. Thus, airlines are rushed last minute to verify passenger and flight crew information, causing delays. Reducing the redundant check-in process alone will speed up the flow of passengers through airports.

AI and robotics to lead airport services

In line with the trend toward self-service and passenger interactions with technology, airports and airlines are implementing AI and robotics to improve the passenger flight experience and make it more personalized.

Last year, Incheon International Airport (ICN) in Korea added LG’s robots to its service team – the Airport Guide Robot and the Airport Cleaning Robot. The Guide Robot roams the terminals, ready to help out a passenger in need with airport and flight information in English, Korean, Chinese and Japanese. The bot even personally escorts travelers to the right terminal or boarding gate when passengers scan their boarding passes. The Cleaning Robot cleans nonstop, and can even detect dirty areas, analyze cleaning patterns and calculate the most efficient cleaning routes.

Haneda Airport in Japan is also testing 7 different types of robots equipped with AI software to cover security, translation and baggage transportation. Investment in robotics is crucial for a country like Japan where there is a severe labor shortage due to low birth rates, and the airport is planning to have their bots up and running by 2020, in time for the Olympic Games in Tokyo.

Passengers will also be greeted by a robot named Josie Pepper at Munich Airport’s Terminal 2. Josie Pepper functions on IBM Watson’s IoT and AI technologies. Her high-performance processor with a WLAN internet access connects to a cloud service that is also linked to airport data to deliver information to passengers in real-time. Moreover, machine learning allows Josie Petter to collect and analyze data and improve her responses over time instead of repeating inputted text.  

The bigger the better

The use of technology will greatly improve the passenger flow through airports and increase passenger capacity. However, the new software systems will work best when accompanied by upgraded airport infrastructure. That’s why airports all over the world are undergoing expansion projects including Heathrow Airport (USD 17.3 billion), Sharjah International Airport (USD 400 million) and Auckland Airport (USD 160-180 million).

ICN recently finished and opened its new Passenger Terminal 2, expanding the airport’s capacity to 72 million passengers and 5.8Mt of cargo every year. The terminal was built using 380 tons of POSCO’s 446M stainless steel that contains high amounts of chromium (26%) and molybdenum (2%) for maximum corrosion resistance against the airport’s coastal climate. Moreover, an innovative Bead Blast process was used to process the stainless steel to create a rough texture to decrease sunlight reflectivity for aircraft pilots during take-offs and landings.

As with ICN, ongoing and future airport expansion projects are projected to consume vast amounts of high-quality steel that is superior in strength, corrosion-resistant and boosts the safety of passengers and flight crew. The renovated infrastructure will further be enhanced by new software upgrades, and future airports will be vastly more efficient and passenger-friendly.

What’s more, manufacturing is no longer a rigid industry that produces uniform, one-sided goods. There is constant communication between customers and businesses for hyper-customization. Not only that, machines and products communicate within a smart factory, and factories exchange data with other factories. Manufacturing is no longer limited to production plants. Moreover, the data generated in the manufacturing process is combined with customer information, and a new service can be created. This combination of manufacturing and services is resulting in creation of added value. In the midst of such drastic change, how can companies stay competitive?

Staying Competitive Through Connection and Convergence

Global manufacturing companies are at the forefront of the 4th Industrial Revolution, as evident in their smart factories. A smart factory collects data generated from the production process using ICT technology, and the system controls all processes from material input to the final product. This has led to flexible production systems with the ability to make various products in one factory or to expand the range of products on the basis of connectivity. Typically, when a company builds a smart factory, it can improve productivity by 20 to 30 percent. A 20 percent improvement in efficiency in the manufacturing sector is a significant, outright increase in global competitiveness.

If the productivity of a plant can be improved through smartization, it is important to also think about connectivity with the ecosystem that exists outside of the plant. Once a smart factory is built, all the data from customer orders to production and delivery are collected in a system via sensors. The customer, product and production data create meaningful connections with each other and provide extensive insight. Examples of added value creation through meaningful connections include hyper-customized goods, data-driven after-sales services to customers and collaboration among companies connected within the smart factory’s external ecosystem. Such advancements will lead greater product quality, production stability as well as shortened delivery times between value chain suppliers.

The Adidas Speed Factory and GE Brilliant Factory are examples of successful smart factories. Adidas customers choose the materials, colors and design of their sneakers, and have them manufactured and shipped within 24 hours in an automated factory.

GE has built a system that can produce all of their widely-diverse products in one factory. When the factory receives customer orders, it operates in a flexible production system which starts with the necessary raw materials, inputted by the automated scheduling system that controls the entire production process, including the final distribution system.

The Future of Manufacturing

Overall, the adoption of innovative changes in the manufacturing sector is likely to progress from lighter industries to the heavy industries, from B2C to B2B sectors. Small plants, quick manufacturing and B2C companies can more readily adapt to rapid technological and market changes. On the other hand, heavy industries like steel and B2B companies with continuous and heavy manufacturing, large production volume and numerous linked companies are likely to be slower to adapt to changes.

For example, adapting to the changes of the 4th Industrial Revolution in the steel industry may be slow, but it is inevitable. What’s more, the long-term adaptation process is more likely to be systematic and deliberate.

As a leading company in the global steel industry, POSCO is pursuing a long-term, systematic “Grand Design” to reinvent its systems to align with the changes of the 4th Industrial Revolution.

First, POSCO built a pilot smart factory in their steel mill, Gwangyang Steelworks, in 2015 that is currently in operation. The company used IoT to collect big data on site, analyze it in real time and build a smart factory that enables optimal control through AI and self-learning. As a result, the Gwangyang Steelworks is reaping the benefits of a smart factory not only in cost reduction but also in improved steel quality, minimized malfunctions and a safe and stable production environment. This year, POSCO plans to expand and apply smart factories to all of its production processes.

POSCO built a smart factory in Gwangyang Steel Mill.

Smart factory application throughout the entire steel mill will improve overall efficiency through a flexible production system. In addition, the factory will be able to respond directly to various customers in real time based on platform construction with customers within the connected ecosystem. The customized characteristics and design of the steel grade for each customer can be applied to production in real time.

Ultimately, a smart ecosystem that links manufacturing, processing and distribution with customer input will lead to a new, innovative ecosystem within the steel industry. In Europe, some companies are experimenting with material libraries and steel distribution platforms. The material library displays a variety of materials for customers to see, touch and test the workability and performance of the materials, and get information about the characteristics, design and delivery times through the order platform. Customers can designate the shipment date on the spot. This will be one of the new promising business models that steel and other material companies will strive towards in the coming future.

POSCO’s Grand Design includes a step-by-step approach to smart factories to expand the use of IoT, AI and Big Data in its production systems. To this end, POSCO ICT has developed PosFrame, a standard software platform that collects basic data of production processes and collectively manages, controls and analyzes the information.

POSCO uses its software platform, PosFrame, for data collection and analysis.

When the software becomes standardized and reliable enough to extend to other sectors, it will be applied to other business areas such as energy and construction, as well as to POSCO’s affiliates.

Manufacturers will have to take into account the heavy production environment, the slow industrial change cycle and the complexity of related industries and affiliates to implement the most effective, long-term, systematic upgrades to its production systems. This will result in a brand-new production and business model for manufacturing companies that will align with the new environment of the 4th Industrial Revolution.
