Where we can find them?

In fact, wearable robot is already introduced in various fields. Wearable robot is applied not only for people with disabilities (paralysis of the whole body or partially) but also protection for employees from harsh conditions or life support purpose for the elders. For instance, the Korean steel manufacturing company, POSCO has applied wearable robot to manage the refractory in furnace which gave the advantage of increasing productivity by 12.6 billion won (worth as approximately 12.9 million US dollars). (Source: “Current level of Korean wearable technology?” (2016). Donga Ilbo).

The technology has brought a great improvement in terms of efficiency, enabling to save 54 days to finish the process consequently saving 12.1 billion won (worth 121 million US dollars) and the less human resources are requited that worth saving 8 hundred million won (worth 100 thousand US dollars). Furthermore, wearable robot is introduced into diverse fields such as supporting fireman or VR (virtual gaming).

Is it realistic?

You can imagine the world famous move ‘Iron man (2008)’. In the movie, when Tony Stark (main character in the movie) simply calls the Iron man suit, it comes to his body automatically. As the series goes on, the technology of the suit also dramatically developed. Recently, news from the movie ‘Avengers: Infinity War’ stimulate the curiosity of new advanced technology of the Iron man suit.

What makes that wearable robot get close to our real life rapidly? Significant improvement of wearable robot compartment such as electric motors, battery, processors can be the reason. But most of all, innovative development of material is the key factor.

Light weight, flexibility and endurance are the fundamental elements

Why materials?

Since the wearable robot is designed to fit in human body, the light weight of the structure is fundamental. Recommended materials for designing wearable robot need to be reinforced plastic or even lighter and have more flexibility.

High impact is another factor that wearable robot need to endure. The physical force of walking is the same amount of force that can bend 5mm X 10mm thickness of aluminum stick. Therefore, structure of the wearable robot should have adequate strength to protect the people who wear them. This is the reason why most of the wearable robots are made of alloy materials.

Therefore, the fundamental element for the success of wearable robot will be application of light and high impact materials into wearable robot’s structure. One of the good examples is “GIGA Steel” that has been recently invented by POSCO providing significant impression to robotic scientists by showing advanced quality on both hard impact and workability. GIGA steel is also recommendable for custom manufacture.

Pack of robots working in the factory is not just all about 4th industrial revolution. Wearable robot may play in a crucial role in improving human quality of life. With wearable robot’s help, walking disability might be considered as little discomfort in near future. Korea is one of the leading countries in wearable robotic fields and POSCO’s advanced technology may influence huge impact on the wearable robotic fields.

The U.S. is headed towards a major shortage of truck drivers. (Source: The New York Times)

However, the U.S. is short of about 30,000 to 35,000 drivers for every 750,000 trucks, and the number of driver shortages may reach up to 245,000 by 2022. That’s because right now, the average age of truck drivers in the U.S. is 55, and potential new recruits are choosing to sign up for construction or manufacturing jobs instead.

All this leads to climbing prices for freight transportation. Last December, at the peak of holiday deliveries, U.S. companies saw the highest monthly average rate for freight transportation since 2010. The high operation costs and lower profit margins are putting a heavy strain on industries. Heading into 2018, companies have to compete for carriers as there is just one truck available for every 12 loads.

As a result, Major automakers are heavily invested in autonomous electric freight trucks such as Tesla, Volvo and Daimler, and there are many proponents of an eco-friendly, safe and driverless future for freight transportation. However, autonomous freight trucks are not a realistic option for companies just yet. At a time of transition between the old and the new, there is a serious lack of capacity in freight transportation, and companies are left to deal with the higher costs for delivery.  

But good news right around the corner

Although the driver shortage is a major concern, it is a natural phenomenon in the transition towards a safer, more sustainable and more efficient freight transportation industry.

Already, Uber has its autonomous trucks on the highways of Arizona. Every truck does have a human driver present to take over anytime, and the company uses transfer hubs to transfer goods between highways and local roads. Autonomous trucks are the safest and most efficient for use on highways, so human drivers transport goods from highways to the final destination. The company is working to operate without human backup drivers in the near future.

Speeding up delivery

Numerous other automotive and tech companies besides those mentioned above are getting ready for autonomous freight transportation. The faster autonomous freight trucks are able to operate commercially, the faster industries can cut costs, improve delivery times and reduce their carbon footprint.

This means software technology, high-capacity batteries as well as the right automotive materials will play a crucial role in the future of the freight transportation industry, as well as in related industries. This transformation will open up new business opportunities for automakers, software companies as well as steel manufacturers like POSCO.

For autonomous truck manufacturers looking for ultra-lightweight yet super strong materials for optimal fuel efficiency, POSCO developed POSCO GIGA STEEL. The advanced high-strength steel (AHSS) material is 3 times stronger and 3.5 times cheaper than aluminum. Steel is also 100 percent recyclable and an electric vehicle made of AHSS requires 30 percent less energy than aluminum throughout its entire lifecycle. POSCO also developed a premium non-oriented electrical steel called Hyper NO for the most advanced and sustainable electric motors.

POSCO also works with its auto partners to research and provide customized technology and materials solutions for their autonomous EVs. In the midst of a critical shortage of truck drivers, POSCO hopes to speed up autonomous EV adoption both for personal and commercial transportation and aid the transition into a more efficient and environmentally sustainable economy.

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.

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.

SEE ALSO: How Factories Produce Steel – the Smart Way

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.

The fourth industrial revolution is heralded by big data, the internet of things, artificial intelligence, virtual reality and augmented reality, 3D printing and other technological innovations. It’s happening at rapid speed. The steel industry needs to keep up and take advantage of all that this revolution has to offer.

However, the industrial revolution did not happen overnight, and advancements in human development traces back to the Iron Age.  

The Iron Age and How it Impacted Civilization

After the Bronze Age was the Iron Age. People started using iron and steel for tools. This was a huge shift for the world, and helped improve nearly all spheres of life from the spread of written language to more effective agricultural practices. Iron offered more choice. People could forge this material into whatever they needed for tools, weapons, or ornaments and decor.

Blacksmiths would have used tools like this during the Iron Age.

Tools and weapons created during this era often used steel, which was a vast improvement on the bronze items from the previous age. Items made from steel were just as light as bronze, but stronger, so users were able to get more out of each item they created. The strength of these tools made it possible for farmers to plant and harvest more land, faster. It enabled people to sell or trade for livelihood.

The Iron Age is a great example of how the right materials can make life better for everyone.

The New Structure of Steel

As the world moves through the fourth industrial revolution, it is evident the same thing is happening. Instead of improvements in specific materials and tools, however, technology is changing things.

The steel production process can be completed autonomously if the fourth industrial revolution continues the way it is going. This means that manufacturers will be able to have very detailed and thorough control over production, using smart technology that will factor in every element from the surrounding environment to minute details of the material itself. The steel production process will be able to use real-time data to optimize every facet of operations, saving money and time.

The steel value chain is affected by changes in the provision of after-sales service, owing to new technology. Manufacturers can use smart technology to track how users interact with their completed products and offer better customer service as a result.

Again, real-time information comes into play, allowing steel companies to see exactly how orders are being created, fulfilled and used, as it is happening. Customer needs are met with ease and speed, all tracked and analyzed digitally.

Competition in the steel industry will be affected by this revolution, too. Competitors can see how other companies are using big data and automation to save money and offer a better customer experience, and use those details to revolutionize their offerings. Online steel transaction platforms make this transparency even more accessible, for companies and clients alike.

Implications on the Steel Industry

To keep up with this revolution, and make the most of it, steel companies need to understand the implications on the industry and plan for the future. New technology is only going to become more widespread, more common, and more advanced. Companies need to be ready to react.

Integrating technology and smart software is the ideal way for steel companies, and the industry at large, to take advantage of this new revolution and use it to create better products and better customer relationships.

To get an idea of how to best integrate new tech into existing steel practices, POSCO’s smart steel factory is a prime example, currently being tested at the Gwangyang Steel Mill. POSCO’s smart factories will collect and analyze all of the microdata generated in the steel production process, to determine the cause of every event that impacts quality or production in general.

An image of how POSCO’s Smart Factory will be run.

From facilities to energy and environment, to safety and conditions, the smart factory will monitor everything. And it will respond accordingly to make the best quality steel possible.

Self-learning artificial intelligence ensures that the process of steelmaking is carefully controlled, with adjustments made in real-time to directly and positively impact the result. The smart factories will use technology to fill the gaps where human capabilities are simply no match for software.

The world has come a long way since the Iron Age and through the various industrial revolutions. In the current fourth industrial revolution, steel companies have to take advantage of new technology and innovations by figuring out ways to apply them to steelmaking processes. POSCO has made this a top priority as it continues to research, educate and implement smart technologies to its production processes and materials and will lead the way for steel companies to follow through the fourth industrial revolution.

“POSCO must continue to take up the challenge of implementing a smart POSCO in preparation for the dawning of the 4th Industrial Revolution. We will apply smart technologies to all processes of the steel mills, as well as to management areas such as finance, HR and purchasing to realize the concept of smart management,” stated POSCO CEO Ohjoon Kwon. “We will actively share the results of POSCO’s smartization process with our group affiliates and customers.”

Mi-hwa Park, head of the POSCO Information Planning Department added, “To realize a smart POSCO, we started the Smart Solution Council headed by our CEO last year, and identified 141 smart projects which applied Big Data and AI to solve practical problems. Approximately 600 employees participated in the projects and reduced costs by KRW 15.7 billion.” She added, “We will develop a POSCO-style SME smart factory model to support innovations for the manufacturing sites of our SME customers and suppliers. Furthermore, we will contribute to fostering SMEs and creating jobs by providing a lighter version of the PosFrame, developed by POSCO, as a customized smart platform for SMEs.”

POSCO also recognized projects that applied Big Data and AI, for excellence in the steel production category. Out of the four, one improved the flatness of steel sheets and another provided improved technology for slab production. The “3D-based design/construction quality improvement” project that uses POSCO E&C’s Virtual Construction to predict risks, and the “power generation output through condenser performance diagnostics” project that can accurately detect errors in POSCO Energy’s power plants were also among those selected.

Forum participants were given an opportunity to experience POSCO’s smart solution platform PosFrame firsthand. PosFrame combines operational insights and IT technology to collect Big Data as well as process and monitor data in a way that allows participants to experience the reality of “Smart POSCO.” It was one of the most popular features of the forum among participants.

POSCO CEO Ohjoon Kwon looking at a PosFrame platform

POSCO also announced its plan to standardize the technologies and processes developed through smart projects, turn them into a technical package and actively incorporate them into its “Smart Solution” business to create added value.

Ki-won Na, CEO of Shinheung Automotive Co., Ltd., an automotive parts maker, said, “We received a lot of ideas applicable to our operations from the case studies presented today, and if we learn about POSCO’s Big Data analysis and utilization techniques in more detail and apply them, I expect it will greatly contribute to improving our productivity.”

POSCO joined hands with POSTECH to launch an advanced AI course earlier this year and is currently training 25 internal AI experts so that they can apply their AI knowledge in their field to solve problems and thus lead the way for a smart POSCO.

Also, POSCO has begun providing free AI education to young, underprivileged jobseekers in July and is now training 100 youths per year on both theoretical and practical knowledge. POSCO is also planning to support the customized SME smart talent development project, including practical education on AI and Big Data skills, for its customers and suppliers.

POSCO is actively planning to complete its smartization, meaning it will apply its “Smart Factory” to all processes of the steel mills, and carry out its “Smart Solution” business, which combines POSCO’s product technologies and services with smart technologies.
