The dawn of Industry 4.0
With Industry 4.0, the manufacturing sector has entered a new era of technological transformation. The combination of automation, data analytics and artificial intelligence (AI) has brought enormous efficiency gains to the factory floor, and the advent of robotics has led to even greater productivity and flexibility. This has changed the way factories operate, revolutionizing the world of manufacturing with smarter, connected, and more self-sufficient factories.
The adoption of Industry 4.0 technologies results in reduced production costs, lower waste, and greater productivity, which all contribute to a more efficient and optimized manufacturing process. The revolution has begun and will continue to transform the factory of the future.
In this article, we will delve deeper into the role robotics plays in transforming the factory of the future, exploring different applications and real-life examples.
The benefits of robots in manufacturing
Traditionally, the use of robots in manufacturing has been focused on repetitive tasks, such as welding and painting, where they could replace human labor, but recent advancements in technology have expanded their capabilities. Now robots can learn and adapt, making them more flexible and useful for tasks that require quick tool changes and agile movements.
Robots improve manufacturing in various ways such as:
- Increased productivity and efficiency
- Enhanced quality and precision
- Reduction in human error and accidents
- Improved safety conditions by working in hazardous environments
- Greater flexibility and versatility to meet customer demands
For example, car manufacturers use robots with mounted cameras to inspect the entire length of car frames in real-time, reducing the time it takes to inspect a car from several minutes to a few seconds. Drone manufacturers use robots to assemble and test their products quickly, accurately, and with a high degree of precision. As robots have become more sophisticated, they have changed the manufacturing landscape dramatically and enabled new businesses to emerge.
The impact of automation on jobs
As with any significant technological change, concerns have arisen about the impact of robotics and automation on employment. According to the International Federation of Robotics, the global manufacturing industry is estimated to use about 2.6 million industrial robots by 2019. As the number of robots increases, many fear that job losses will inevitably follow.
While it is true that some of the repetitive and low skilled jobs will disappear, the automation of manufacturing processes will also create new types of jobs. People with the skills to design, program, and maintain robots will increasingly be in demand, providing opportunities for those with a strong technical background.
Additionally, the implementation of robots in manufacturing will also improve overall employee safety. Robots can undertake dangerous or hazardous tasks that would otherwise be performed by human laborers, thus reducing the number of accidents that might occur in a factory. Not only does this save human lives, but it also makes factories more productive and efficient.
Real-life examples of robotic automation
Smart factories with robotic automation
The Smart factory concept has significantly transformed the manufacturing sector, where automation has been the hallmark of production for quite some time. The addition of robots to the factory floor has allowed for greater efficiency and production rates, along with lower overall costs. In the smart factory setting, robots are an essential part of the production line, working alongside humans to accomplish complex manufacturing tasks.
The Siemens Electronic Works (SEW) facility in Amberg, Germany, is considered one of the most advanced smart factories globally, producing a range of automation equipment. The facility has total control over the manufacturing process, leveraging data from robots, sensors, and other manufacturing tools to detect bottlenecks in the production line, identify non-conformance, and predict maintenance needs. The facility is optimized for quick changeover, a feature which helps SEW respond to changing customer demands.
Collaborative robots (cobots)
Traditional robots are usually large and often perform tasks that require a considerable amount of space. In contrast, cobots, or collaborative robots, often have human-like appearances and can work alongside humans productively. Cobots are designed to be safe around people, with sensors and other features that allow them to detect and avoid obstacles or stop if a human gets too close.
According to market research by Markets and Markets, the global market for the collaborative robot is expected to reach $9.7 billion by 2025, up from just $710 million in 2018. One advantage of cobots to manufacturing companies is the reduced cost of automation and increased flexibility, allowing smaller manufacturing firms to adopt automation. Cobots can take over tasks such as packaging products on the packaging line, thereby freeing up employees to work on tasks that require human skills, such as customer service and maintenance.
Computer vision in robotics
Computer vision is an important element of the robotics revolution, leading to the development of robots with intelligent “eyes”. These robots can see, detect, and respond to changes in the environment around them, improving their accuracy and efficiency in handling tasks. Computer vision is particularly useful in the automotive industry, where robots are used for many tasks, such as painting, welding, and assembly of car components. With computer vision, robots can identify the edges of a car and calculate the optimal painting trajectories. As a result, the quality of the paint job comes out better than if it were done manually.
The future of robotics in manufacturing
With the rapid development of technology, robots continue to move beyond the factory to other sectors of the economy. In the healthcare sector, for example, robots can undertake tasks such as diagnostics, surgery, and rehabilitation therapy. In the warehouse sector, robots can help with order picking and goods transportation, while in logistics, they can support management and improve last-mile delivery to customers.
The future of robotics in manufacturing appears bright, with new technologies such as artificial intelligence and machine learning set to revolutionize the manufacturing sector even further. Robotics will enhance the overall supply chain, make factories more efficient and cost-effective, and enable manufacturers to react better to consumer demand.
Conclusion
Robotics and Industry 4.0 are transforming the factory of the future. As the manufacturing industry continues to evolve, the adoption of robotics and the implementation of technologies such as data analytics, artificial intelligence, and automation will continue to grow. Robots provide multiple benefits, from increased productivity and efficiency to enhanced safety and quality control. The robotic automation of manufacturing is a game-changer, leading to improved competitiveness, a more sustainable environment, and a more prosperous and healthy society. The future of manufacturing is exciting, and we can’t wait to see what’s next!
