Boston Dynamics officials have spent the past month touring South Korean auto-parts factories, according to KED Global, accelerating supply-chain vetting as Hyundai Motor Group locks in plans to deploy more than 25,000 Atlas humanoid robots across its manufacturing network by 2028.
Hyundai Mobis Anchors the Actuator Tier
Hyundai Mobis (012330.KS), the group's Tier-1 components arm, has secured the lead actuator-supply role for Atlas — the first commercial robotics customer win in the company's history. Actuators, which convert control signals into physical movement, represent approximately 60% of a humanoid robot's total bill of materials, making Hyundai Mobis' position structurally significant as volumes ramp.
The company plans to build a dedicated mass-production line for actuators and intends to expand its humanoid portfolio to cover hand grippers, sensors, integrated controllers and battery packs. A North American robot factory announced in August 2025 is designed around a 30,000-unit annual capacity target — the same ceiling Hyundai Motor Group set for its own Atlas deployment.
HL Mando Targets Multiple Platforms
HL Mando (204320.KS) enters the race from a different angle. The independent auto-parts maker already supplies actuators for Boston Dynamics' Spot quadruped robot and is expanding North American production capacity to pursue contracts with Tesla's Optimus programme, targeting the fourth-generation model given that third-gen components are expected to carry a high share of Chinese-made parts.
The dual-platform posture — Boston Dynamics for Atlas and Tesla for Optimus — positions HL Mando as one of the broadest actuator suppliers in the emerging Korean humanoid ecosystem, which also includes LG Innotek (011070.KS, vision sensing), LG Energy Solution (373220.KS, batteries), Samsung SDI (006400.KS, cells), and smaller specialists SL Corp, Hwashin Precision, SOS Lab and Samhyun.
Deployment Scale and Economics
Hyundai Motor Group has committed 25,000-plus Atlas units to its own Hyundai and Kia plants — roughly 83% of the 30,000-unit annual production run the group is targeting by 2028. The remaining 17% is earmarked for third-party industrial customers. All 2026 Atlas deployments are already fully allocated, with early fleets shipping to the group's Robotics Metaplant Application Center (RMAC) and to Google DeepMind.
Boston Dynamics has priced Atlas below USD 320,000 per unit — calibrated to undercut the two-year fully loaded labour cost of two US manufacturing workers — a threshold that makes the economics straightforward for high-volume assembly operations seeking to automate repetitive or hazardous tasks.
Sector Tailwinds
Morgan Stanley projects the global humanoid robot market to expand nearly 60-fold by 2040. South Korea's auto-parts industry, already restructuring around electrification, is positioning humanoid supply-chain contracts as a second growth wave. Boston Dynamics' active factory-floor tours of Korean suppliers — KED reports the visits began in early June — signal that supplier qualification is moving from memo of understanding to production-line audit.
For Hyundai Mobis and HL Mando, the race to supply Atlas actuators mirrors the EV battery-module build-out of 2019–2022: an incumbent auto-parts logic applied to a new powertrain, with first-mover cost curves that compound over successive platform generations.
