LG Is Building a One-Stop Shop for Humanoid Robot Parts
When a humanoid robot manufacturer needs a joint, they go to an actuator company. When they need eyes, they go to a sensing company. When they need power, they go to a battery company. LG is betting it can be all three.
LG Group has five affiliates now developing products specifically for humanoid robots, a coordination play that mirrors the conglomerate's existing "One LG" approach in automotive parts and AI data centers — where each subsidiary sells its specialty into integrated pitches to single clients. No formal label has been applied to the robotics push yet. But the structure is becoming recognizable, and it represents the most explicit attempt by a Korean conglomerate to position itself as a bundled subsystem supplier for the global humanoid buildout.
LG Electronics CEO Lyu Jae-cheol declared 2026 the "inaugural year" of the company's humanoid robotics business at its annual shareholders meeting. The centerpiece is the Axium actuator line, first shown at CES 2026 in January, now being prepared for mass production as a B2B product sold to global robot manufacturers. The manufacturing base is existing: LG produces 45 million appliance motors annually, and the company is retooling that operation for the robotics market. Lyu said mass-production capacity would be ready by year-end.
LG Innotek is handling the eyes. The company has begun early output of composite sensing modules combining cameras, lidar and radar for humanoid clients. CEO Moon Hyuk-soo declined to name clients publicly, but Korea Herald reported LG Innotek is in active discussions with major US and European robot manufacturers, including Boston Dynamics and Figure AI. Moon set large-scale production around 2027 to 2028, projecting hundreds of billions of won in robotics revenue by 2030.
LG Energy Solution is working on the power layer. At InterBattery 2026 in Seoul in March, the company displayed sulfide-based all-solid-state battery cells designed specifically for humanoid robots, outlining a dual-track plan: graphite-anode solid-state cells for EVs by 2029, and anode-free solid-state cells for robots by 2030. Anode-free design maximizes energy density per unit volume, a genuine constraint for machines that must fit a battery inside a human-shaped torso alongside dozens of motors and circuit boards. The company is reportedly in supply discussions with six or more global robotics firms, though none have been publicly named.
LG Display and LG AI Research complete the group's coverage. LG Display has demonstrated a 7-inch flexible OLED panel for robot faces, repurposing curved plastic OLED technology it already supplies for Mercedes-Benz dashboards. LG AI Research is developing the Exaone vision-language model that runs the KAPEX humanoid co-developed with the Korea Institute of Science and Technology.
The structural logic is not hard to follow. Actuators represent an estimated 40 to 60 percent of a humanoid robot's total build cost, making them the single largest component expense. Batteries rank next as a critical constraint. Sensing systems add another layer. Each of these involves manufacturing complexity that favors suppliers with existing scale — and LG affiliates hold established positions across all of them. The bet is that bundling reduces coordination costs for robot manufacturers trying to bring a humanoid to market at scale.
This is a supply chain story more than a product story. LG is not building a robot to compete with Figure or Tesla or Boston Dynamics. It is building the parts infrastructure that all of them need — and trying to own the interface layer between the robot manufacturers and the component suppliers. Whether that position holds depends on whether the humanoid market actually reaches the volumes that justify these manufacturing bets. Mass production timelines of 2026 to 2030 are ranges, not commitments.
The broader race among Korean conglomerates to secure humanoid supply chain positions is real. Hyundai has Boston Dynamics. Samsung has semiconductor and sensor plays. LG has actuators, sensing, batteries, and displays — a broader coverage than most. The question is whether the bundled offer is a genuine advantage or just a conglomerate marketing frame for affiliates that happen to be developing robotics products independently.
For now, the parts are real. The timelines are specific. And the clients LG Innotek is courting — including Boston Dynamics and Figure AI — are real companies with real humanoid programs. That is enough to make this a supply chain story worth tracking.
