Hyundai Mobis (KRX: 012330): Humanoid Robot Actuators and Auto Parts
Hyundai Mobis makes brakes, airbags, headlamps, electrification systems and infotainment for one of the world's largest carmakers — about 61 trillion won of it in 2025. At CES 2026 it added one line to that list that changes how the company gets discussed: it will supply the actuators for Boston Dynamics' next-generation Atlas humanoid.
Who they are
Hyundai Mobis is the parts arm of Hyundai Motor Group, and one of the largest automotive suppliers in the world. Its business splits cleanly in two: module assembly and component manufacturing — the low-margin, enormous-volume half that feeds Hyundai and Kia assembly lines — and after-sales parts, the smaller, far more profitable half that keeps 20-year-old cars on the road.
In 2025 that combination produced record results: revenue of KRW 61.12 trillion and operating profit of KRW 3.36 trillion, the first time revenue cleared 60 trillion won. Module and core parts contributed KRW 47.80 trillion; after-sales parts KRW 13.32 trillion. Notably, the module division turned an operating profit for the first time in years, helped by North American electrification plants ramping and a richer mix of high-value electronics.
The company has also been reshaping the portfolio at the edges — in January 2026 it signed an MOU with France's OPmobility SE to sell its lamp business. Selling lamps and buying into robot joints is, in one sentence, the strategy.
What they do
The robotics entry is not a pivot; it is an adjacency. An actuator converts a control signal into physical movement, and Mobis has been mass-producing that category for decades under different names: electric power steering, brake actuators, active suspension, e-drive units. The manufacturing problem — hold tight tolerances, at automotive cost, at automotive reliability, a million times over — is the same problem.
By the company's own framing, actuators represent more than 60% of a humanoid robot's material cost, which is why this is a bigger deal than the word "component supplier" suggests. Korean coverage puts the combined share of joint, hand and tactile modules at 60–70% of total manufacturing cost. Whoever wins the actuator socket wins most of the bill of materials.
Mobis formalised a mid-to-long-term robot actuator plan at its CEO Investor Day in August 2025, then announced the Boston Dynamics collaboration at CES 2026 in Las Vegas. The stated scope goes beyond parts: standardising key components, optimising designs for manufacturability, and building a reliable supply chain for the group's robotics platform. Sell-side coverage indicates U.S. actuator production is targeted for 2028, with grippers, battery systems, controllers and perception modules under evaluation as follow-on items.
How they make money
Today, almost entirely from cars. Robotics contributes no meaningful revenue yet, and Mobis has not disclosed contract value for the Atlas actuator supply. What it has disclosed is the shape of the opportunity: Hyundai Motor Group's $26 billion U.S. investment programme includes plans to build and deploy tens of thousands of robots, and reporting points to a dedicated robot plant near Savannah, Georgia sized around 30,000 humanoids a year, targeted for 2028.
There is a second, subtler thread: Mobis has been an investor in Boston Dynamics, not just a supplier. It put roughly $222 million into the company when the group acquired it in June 2021, followed by indirect investments through HMG Global capital increases — about $43 million in May 2024 and $106 million in August 2025. In June 2026 Hyundai Motor Group bought out SoftBank's remaining 9.65% stake for $325 million, taking full ownership of Boston Dynamics.
Shareholder returns remain a stated priority alongside all of this: the company has committed to a total-shareholder-return policy above 30% for 2026, with quarterly dividends and buyback-and-cancellation continuing.
Where it sits in the value chain
Mobis occupies Stage 3 — Actuators, screws & joint modules, the layer where the industry is shifting from buying discrete parts to buying complete, safety-rated joints. It buys from Stage 2 (reducers) and Stage 1 (magnets in the motors), and sells to Stage 7 (robot builders).
What makes this stage strategically loud in 2026 is who is entering it. Schaeffler signed a five-year actuator supply agreement with UK developer Humanoid covering more than a million joint actuators. Sanhua grew robotics revenue 320% year on year in a half-year period. HL Mando already ships actuators for Boston Dynamics' Spot. All of them are automotive-scale manufacturers deciding that humanoid joints are a familiar problem — and they are broadly right, which is bad news for the specialist robot component makers whose margins depend on it being unfamiliar.
The bigger trend
Hyundai Motor Group has assembled something no other humanoid contender currently has in one ownership structure: the robot platform (Boston Dynamics), the actuator supplier (Mobis), the logistics arm (Glovis), a dedicated training centre, and the factories where the robots are meant to work. Atlas production began in 2026 with output committed to the group's own robotics centre and to Google DeepMind, and deployment across Hyundai plants is planned from 2028.
The risk in that vertical integration is the same as its strength. A captive supply chain moves fast and hides pricing signals. Boston Dynamics' own CEO has said Atlas needs to learn new factory tasks in a day or two and hit 99.9% reliability before it is genuinely useful on a factory floor — a bar the whole industry is still short of. Until robots do paid work for third parties, Mobis's robotics revenue is an intra-group transfer with excellent optics.
What to watch
- Whether Mobis discloses actuator order value or volume for Atlas, rather than describing the relationship qualitatively.
- Confirmation and siting of the U.S. actuator production line targeted for 2028, and whether the Georgia robot plant proceeds at the reported scale.
- Expansion of scope beyond actuators into grippers, controllers, battery systems and perception modules — the difference between a parts supplier and a drive-system integrator.
- Any robotics customer outside Hyundai Motor Group.
- Margin trajectory in the core module business, which still funds all of this.

FAQ
What exactly did Hyundai Mobis agree to supply Boston Dynamics?
Actuators for the next-generation Atlas humanoid, under a strategic collaboration announced at CES 2026 on January 7, 2026. It is Mobis's first official robotics customer. The two companies also said they would work together on component development pace and building a reliable supply chain; contract value has not been disclosed.
How big is robotics for Hyundai Mobis financially?
Negligible today. 2025 revenue was KRW 61.12 trillion, essentially all automotive, split between KRW 47.80 trillion of module and core parts and KRW 13.32 trillion of after-sales parts. Robotics is a strategic adjacency at the design-win stage, with U.S. actuator production reported to be targeted for 2028.
Why are actuators such a valuable part of a humanoid robot?
Because they are most of the machine. Hyundai Mobis states that actuators account for more than 60% of a humanoid's material cost, and Korean industry coverage puts joint, hand and tactile modules combined at 60 to 70% of total manufacturing cost. An actuator bundles a motor, reducer, encoder and sensing into one housing that has to be light, strong and reliable at once.
Is Hyundai Mobis related to Boston Dynamics beyond being a supplier?
Yes. Both sit inside Hyundai Motor Group, which acquired control of Boston Dynamics in 2021 and bought out SoftBank's remaining 9.65% stake for $325 million in June 2026. Mobis itself invested roughly $222 million at the time of the original acquisition and has made further indirect investments through group vehicles since.
