HL Mando (KRX: 204320): From Boston Dynamics' Spot to Humanoid Joints
HL Mando already ships actuators for Boston Dynamics' four-legged Spot robot — a real, existing commercial relationship, not a prototype order. It's now building nine actuator variants across three different drive technologies to get the same access to the humanoid robots everyone actually wants to talk about.
Who they are
HL Mando is a South Korean automotive parts maker built on motor-driven power steering (MDPS), braking, and suspension systems — core, high-precision drive and control technology that turns out to transfer directly into robot joints. Unlike several other automotive suppliers newly entering robotics on the strength of announced intentions, HL Mando already has a live, shipping robotics relationship: it supplies actuators for Boston Dynamics' Spot, the commercially deployed four-legged robot used across industrial inspection applications in more than 40 countries.
That existing quadruped relationship is what makes HL Mando's humanoid ambitions more credible than a cold-start entrant's. The company is explicitly building on its automotive drive and control experience and its Spot supply track record to pursue Tesla's Optimus program specifically, positioning itself as an actuator vendor with genuine field-deployment references rather than only lab-tested prototypes.
What they do
HL Mando's humanoid actuator strategy spans three drive technologies across nine total product lineups: QDD (quasi-direct drive, with reducer capability developed in-house), PRS (planetary roller screw, pursued through licensing and joint-venture arrangements), and harmonic drive (pursued through outsourcing). Running all three technology paths simultaneously, each with a different in-house-versus-partner sourcing strategy, is a deliberate hedge against not knowing in advance which drive technology wins in which joint across a humanoid's body.
Prototypes are already complete and being used in customer marketing conversations, with a "master model" reflecting customer and market feedback targeted for completion in the second half of 2026, alongside a pilot production line in the United States. The company's stated first-priority target customers are North American humanoid robot makers, a positioning that aligns with the broader industry push — visible at CES 2026 — to build supply chains excluding Chinese components for defense-adjacent and Western commercial robot programs.
KB Securities analysts who attended CES 2026 reported that overseas industry contacts described needing hundreds of thousands of actuators weekly for humanoid production at scale, with explicit intent to exclude China from the supply chain — and, notably, insufficient volume available from any single supplier, meaning buyers are actively seeking second-source suppliers. That dynamic favours a credible new entrant like HL Mando rather than punishing it for arriving after Schaeffler or Hyundai Mobis.
How they make money
HL Mando's core automotive business remains the overwhelming majority of revenue: Q3 2025 revenue was KRW 2.32 trillion, up 7% year over year, with operating profit of KRW 94.1 billion, up 14%. Robotics actuator revenue today is disclosed at roughly the KRW 10 billion level — genuinely early stage relative to the company's multi-trillion-won automotive base, and dwarfed even by some smaller Stage 3 peers further along in their robotics build-out.
Meritz Securities framed the key 2026 catalyst explicitly as actuator order confirmation, describing a path where a fourth-generation humanoid actuator win with an unnamed major customer in 2027 and a new North American actuator manufacturing entity established by 2028 would represent the company's value inflection point — a multi-year runway rather than a near-term earnings event.
Where it sits in the value chain
HL Mando sits in Stage 3 — Actuators, screws & joint modules, directly alongside Hyundai Mobis as a second major Korean automotive supplier making the same pivot. The two companies' existing customer relationships differ meaningfully: Hyundai Mobis is tied to Boston Dynamics through Hyundai Motor Group ownership and supplies the humanoid Atlas specifically, while HL Mando's existing Boston Dynamics relationship is with Spot, the quadruped, and its humanoid ambitions are aimed at Tesla and other North American developers rather than a captive parent-company relationship.
That distinction is worth sitting with: HL Mando's humanoid opportunity, unlike Mobis's, is not guaranteed by group ownership. It has to win business from robot makers with no structural obligation to buy from HL Mando, which makes its progress a somewhat cleaner signal of genuine competitive merit — and a somewhat riskier bet, since there's no captive fallback if external customers choose a rival.
The bigger trend
HL Mando's three-technology, nine-variant approach captures something true about the current state of humanoid actuator design: nobody has settled on a single dominant drive architecture across every joint in a robot's body, and suppliers who can offer QDD, planetary roller screw and harmonic drive options simultaneously are better positioned to win whichever specification a given customer settles on. That flexibility costs more to develop than betting on one technology, but it widens the number of design-win opportunities.
The "second-source" dynamic flagged by KB Securities — humanoid makers needing more actuator suppliers than currently exist at scale, with explicit intent to exclude China — is a structural tailwind specific to companies like HL Mando that are Korean, not Chinese, and therefore politically uncomplicated for Western humanoid programs to qualify. That geographic positioning may matter as much as any specific technology choice.
What to watch
- Completion of the "master model" actuator and any resulting named customer order in the second half of 2026.
- Progress on the U.S. pilot production line, the concrete step toward the North American manufacturing entity targeted for 2028.
- Whether HL Mando lands a fourth-generation humanoid actuator design win with a major (as-yet-unnamed) customer in 2027, the milestone Meritz Securities identifies as the key inflection point.
- Growth of the existing Boston Dynamics Spot actuator relationship as a reference for humanoid qualification.
- Robotics revenue disclosure moving beyond the current roughly KRW 10 billion level as design wins convert to shipments.

FAQ
Does HL Mando already supply humanoid robot makers?
Not yet in confirmed production volume. It already supplies actuators for Boston Dynamics' Spot, a four-legged quadruped robot, but its humanoid-specific actuator lineup is still in prototype and customer-engagement stages, with a "master model" targeted for completion in the second half of 2026.
How much of HL Mando's revenue comes from robotics today?
A very small share — disclosed robotics actuator revenue is around KRW 10 billion, against total company revenue in the trillions of won from its core automotive braking, steering and suspension businesses. Robotics is a growth initiative layered on a large, stable existing business.
What actuator technologies is HL Mando developing?
Nine total product lineups spanning three drive technologies: QDD (quasi-direct drive) developed in-house including the reducer, PRS (planetary roller screw) pursued through licensing and joint ventures, and harmonic drive pursued through outsourcing partnerships.
Why is HL Mando targeting North American customers first?
Industry contacts at CES 2026 reportedly told analysts that humanoid makers are actively seeking to exclude Chinese components from their supply chains and need more actuator suppliers than currently exist at scale. As a Korean, not Chinese, manufacturer with automotive-grade precision drive experience, HL Mando is positioned to serve that specific demand.
