South Korea is racing to develop artificial intelligence-powered humanoid robots to address a fundamental economic challenge: an aging, shrinking workforce that threatens the nation's manufacturing competitiveness. RLWRLD, a Seoul-based AI startup, is systematically capturing the skills of experienced workers across hotels, warehouses, and convenience stores to build machine-learning systems that could reshape industrial production within two years.
The startup's approach reflects a pragmatic recognition of demographic reality. Rather than rely on immigration or government subsidies to maintain labor forces, South Korean companies are investing heavily in automation technology that leverages the nation's existing strengths in semiconductors and manufacturing expertise. The government last month announced a $33 million project to capture the "instinctive know-how and skills" of "master technicians" into a database for AI-powered manufacturing, acknowledging that robots may be the most cost-effective solution to productivity challenges.
The Market Opportunity
RLWRLD last week unveiled its robotics foundation model, with expectations that industrial AI robots will be deployed at scale around 2028. Major manufacturers are already committing to timelines: Hyundai Motor plans to introduce humanoids built by its robotics unit, Boston Dynamics, at its global factories in coming years, starting with its Georgia plant in 2028. Samsung Electronics plans to convert all manufacturing sites into "AI-driven factories" by 2030, with humanoids and task-specific robots across production lines.
The company is among a wave of South Korean high-tech firms competing in the global market for "physical AI," a term for machines equipped with AI and sensors that can perceive, decide and act in real-world environments with some degree of autonomy. The competition includes U.S. tech giants like Tesla and a flood of Chinese firms pouring billions into humanoids and other AI robots.
South Korea sees particular advantage in this sector compared to others. Billy Choi, a professor at Korea University's center for Human-Inspired AI Research, said, "South Korea has a highly developed manufacturing sector and the focus is squarely on humanoids tailored specifically for those industries." The nation's deep base of skilled workers in manufacturing and other sectors provides valuable training data—a competitive asset that could offset disadvantages in other AI sectors where English-language proficiency gives U.S. firms major advantages.
How the Technology Works
At Lotte Hotel Seoul, food and beverages manager David Park, who has worked at the hotel for nine years, demonstrated the data-collection process by folding a banquet napkin while wearing body cameras strapped to his head, chest and hands. Park also wiped wine glasses, knives and forks in a banquet hall as colleagues prepared for real services nearby. Each of his motions is fed into a database that will teach robots to perform similar tasks.
RLWRLD is also collecting data from logistics workers at CJ, capturing how they grip, lift and handle goods in warehouses, and from staff at Lawson, tracking how they organize food displays. Hyemin Cho, who handles business strategies at RLWRLD, said, "Capturing motion data in real-world settings is extremely important and the quality of that data matters greatly." Song Hyun-ji of the company's robotics team said the process captures fine details such as joint angles and the amount of force applied.
After converting worker footage into machine-readable data, RLWRLD's engineers repeat the tasks wearing cameras, VR headsets and motion-tracking gloves. That data is used to train test robots, often guided by RLWRLD "pilots" using wearable devices. One of RLWRLD's labs occupies a 34th-floor suite at Lotte Hotel, with infrared laser readers in the corners and a wheeled robot with black, humanlike metal hands moving back and forth beneath a chandelier.
The company is among a smaller group developing AI for five-fingered hands that mimic human touch, rather than the task-specific two- or three-fingered grippers used by most robots, including Boston Dynamics' Atlas. Five-fingered designs may not always suit factory needs, but they could be crucial as robots move into homes, where closer interaction with humans will be required.
Labor Concerns and Industry Reality
The push has unsettled labor groups, which fear robots could eliminate jobs and hollow out the skilled workforce. After Hyundai's union warned in January that robots could trigger an "employment shock," President Lee Jae Myung issued a rare rebuke, describing AI as an unstoppable "massive cart" and calling for unionists to adapt to changes "coming faster than expected."
Kim Seok, policy director at the Korean Confederation of Trade Unions, said, "Mastery of skills is ultimately a human achievement — even if AI can replicate existing abilities, the continuous development of craft will remain fundamentally human." He urged the government and employers to engage with workers over AI to win their buy-in and ease job concerns.
However, industry leaders acknowledge meaningful limitations to automation. Park said, "If you look at the entire process of preparing for an event in back-of-house areas, we think humanoids might be able to take over about 30% to 40% of that workload. It will be difficult for them to replace the remaining 50%, 60% and 70%, which involves actual human-to-human interaction." Lotte Hotel hopes robots will be ready for cleaning and other behind-the-scenes tasks by 2029, and also plans robot rental services for the hospitality and other service industries, with potential expansion to homes.
Although current humanoids would need several hours to clean a guest room that human workers finish in about 40 minutes, the technology trajectory suggests significant productivity gains in specific, repetitive tasks.
Why This Matters:
South Korea's aggressive investment in robotics reflects a market-driven response to demographic pressures that government cannot solve through traditional interventions. Rather than expand welfare programs or mandate hiring practices, the nation is leveraging private enterprise and technological innovation to maintain economic competitiveness as its working-age population shrinks. This approach transfers productivity challenges to the private sector, where companies bear the costs and reap the benefits of automation decisions. The timeline—with deployment expected around 2028-2030—suggests South Korean manufacturers believe robotics will be economically viable within this decade. The labor union concerns, while legitimate, highlight the tension between technological progress and worker transition. The success or failure of this strategy will depend on whether productivity gains translate to broader economic growth that can support retraining and new employment opportunities, or whether automation merely reduces labor demand without creating offsetting economic expansion.
