LG's Quiet Play to Own the Robot Joint Market

The Hidden Layer of the Robot Boom

While headlines about humanoid robots focus on AI brains and brand launches, a quieter battle is taking place over the limbs. LG Electronics has been making its pitch to global big-tech companies not as a robot builder, but as the supplier of the critical components that make movement possible. Its target: the actuator—the device that combines motors and gear reducers to create precise robotic motion, the mechanical equivalent of human joints and muscles.

At IFA 2026 in Berlin on September 5, Baek Seung-tae, head of LG Electronics’ HS Business Division, revealed the company is actively pursuing actuator orders from multiple global technology firms. A key meeting is scheduled for October with a specific company to finalize production readiness and technical specifications. Baek said he hopes to announce a contract win “soon after” that meeting.

This is a significant moment. LG has never before landed a large-scale actuator order for humanoid robots from a global technology company. If it does so this fall, it becomes the first Korean supplier to secure a major foothold in what could become one of the most valuable component markets in the hardware industry this decade.

Why Actuators Are the Bottleneck

A single humanoid robot requires dozens of actuators distributed across its body—each joint demands its own motor, reducer, and control system. There is no industry-standard specification yet. Every humanoid manufacturer designs its own kinematic requirements, meaning every actuator must be custom-engineered. That is both a barrier to entry and an opportunity for a supplier with the right capabilities.

LG’s advantage comes from an unlikely place: six decades of domestic appliance manufacturing. The same motor and precision control technology developed for washing machines, refrigerators, and air conditioners translates directly into the kind of torque control and miniaturization that humanoid actuators require. LG has also internalized its reducer technology, which is a rare capability. Most actuator producers still depend on third-party gear suppliers—a structural vulnerability in a supply-constrained market.

The company plans to have its dedicated robotic actuator brand, LG AXIUM, ready for volume production by the end of 2026. That timeline positions LG to be the first Korean actuator supplier delivering at scale just as the humanoid robot industry is moving from prototype to pre-production.

LG’s Parallel Strategy: Supply and Self-Use

LG is playing a two-track approach. It wants to sell actuators to external humanoid robot makers while simultaneously deploying its own robots internally. Baek confirmed that LG plans to place humanoid robots at its Tennessee facility in the United States and its Changwon smart factory in South Korea in the near term. The logic is straightforward: learn by doing. Manufacturing environments are structured and predictable—the ideal testing ground before robotics expand into unstructured home settings.

This mirrors a pattern seen elsewhere in the industry. Companies that operate their own robotic deployments gain operational data that improves their designs, which in turn strengthens their supply propositions. LG’s approach of using robots internally before selling them externally is strategically sound, though it also raises the question of whether LG will eventually compete with its own customers as a robot integrator.

The broader LG Group context matters here. Chairman Koo Kwang-mo met with NVIDIA CEO Jensen Huang last month to discuss physical AI and robotics cooperation. LG’s entry into the actuator supply chain aligns with a larger group-level push to embed itself in the emerging physical AI ecosystem—not just as an appliance maker adapting to new technology, but as a hardware supplier shaping the industry’s foundation.

The B2B Pivot Is Real

This move is not only about robotics. LG is systematically shifting its business mix toward B2B revenue streams. Baek stated explicitly that the company is expanding its built-in appliance division, commercial washing equipment, and component businesses to reduce reliance on the cyclical B2C market. Actuator sales represent the newest and most ambitious pillar of that strategy.

The structural shift is significant. Consumer appliance margins are under constant pressure from currency fluctuations, raw material costs, and logistics volatility. B2B contracts, particularly long-term supply agreements with technology companies, offer more predictable revenue. LG acknowledged exposure to these variables but argued it has built mitigation through flexible production systems, supply chain diversification, and longer-term contracting.

China’s role in this equation is changing. Baek noted that Chinese appliance manufacturers are no longer able to compete purely on cost—their production expenses have risen substantially, making sustained aggressive pricing difficult. LG plans to differentiate on core component technology, quality, and ease of use rather than engage in a race to the bottom.

Who Wins and Who Loses

If LG secures these actuator contracts, several dynamics shift. Global technology companies building humanoid robots gain a credible non-Chinese, non-Japanese supplier with proven motor and reducer capabilities. That reduces their dependency on the limited pool of established Japanese and European actuator producers and introduces competitive pricing pressure into a market that has historically been supply-constrained.

Japanese actuator makers—particularly Harmonic Drive and Nabtesco, which dominate the precision reducer segment—face a new competitor with deep manufacturing scale and direct relationships with the world’s largest consumer electronics companies. LG’s ability to produce at appliance-scale volumes while maintaining precision is a combination few rivals can match.

Chinese robotics companies that hoped for low-cost actuator supply from domestic manufacturers may find that option shrinking. Rising Chinese production costs and LG’s push into the same component space compress the value chain from both ends.

For LG itself, the stakes are high. Landing a major actuator contract would validate a strategic bet made since at least 2024 and reposition the company from a consumer appliance brand to a critical infrastructure supplier in the physical AI era. Failure to convert its October meetings into signed contracts would leave LG in a vulnerable position—having invested in AXIUM production capacity without the anchor revenue to justify it.

The next six weeks will determine which outcome materializes.
