In this blog post, we’ll explore the characteristics of robotics—which has evolved through the convergence of knowledge from various disciplines, including mechanical engineering—as well as the structure of robotic arms, their control principles, and their role in industrial settings.   When many people hear the term “mechanical engineering,” they likely think of cars, gears, or factories...

In this blog post, we’ll explore the principles behind why lasers produce light that is far more intense than ordinary light sources, using the concepts of stimulated emission, optical pumping, population inversion, and the directionality of light.   “Fire the laser beam!” This is a line often heard in robot animated movies. The green laser beams fired from robotic arms are usually powerful...

In this blog post, we’ll explore the principles, applications, and limitations of finite element analysis—a method that breaks down complex structures, like LEGO sets, into small elements for analysis.   Among the countless toys loved by children, LEGO is a must-mention. LEGO is a toy consisting of colorful blocks of various sizes that are interlocked to build large objects; its appeal lies...

In this blog post, we’ll examine the manufacturing process and uses of cochineal dye—which is used in strawberry milk and various processed foods—as well as its allergy risks and the safety controversies surrounding it.   When you bite into a strawberry, you can see its white flesh. However, strawberry milk—which contains strawberries—is pink. Where does this pink color come from? It comes...

In this blog post, we’ll explore why GPGPUs are used in the deep learning training process, focusing on the differences in architecture and computation methods between CPUs and GPUs.   In the past, the match between Google’s Go AI, AlphaGo, and South Korean professional Go player Lee Sedol, a 9-dan, was a major topic of conversation for some time. AlphaGo is an AI system built using deep...

In this blog post, we’ll examine the relationship between the various chemical products and medications we use in our daily lives and animal testing, as well as the medical value and ethical issues surrounding animal testing, and methods to replace it.   In the morning, as he starts his day, Mr. A wakes up to go to work. He washes his hair with shampoo and conditioner, cleans his body with...

In this blog post, we examine the vast potential of big data alongside the challenges South Korea must address to effectively utilize it, including personal data protection, data ethics, software competitiveness, and the development of specialized talent.   In director Steven Spielberg’s film ‘Minority Report’, the Precrime system prevents crimes in advance based on prophecies...

In this blog post, we will examine nuclear power—which accounts for a significant portion of South Korea’s electricity supply—from the perspectives of environmental impact, safety, economic viability, international examples, and energy security, and assess whether the country should continue to rely on nuclear power in the future.   A look at South Korea’s current electricity generation mix...

In this blog post, we will examine the need for autonomous vehicles, as well as South Korea’s current laws and regulations regarding them, liability for accidents and insurance, passenger transportation and employment issues, safety standards, and performance certification systems. We will then assess whether it is still too early for the full-scale commercialization of autonomous vehicles...

In this blog post, we’ll examine the causes of blackouts—which can occur when the balance between power supply and demand is disrupted—the process of restoring the power grid, past instances of large-scale rolling blackouts in South Korea, and the preventive measures currently in use, such as energy storage systems and emergency power sources.   In the past, large-scale rolling blackouts in...
