LG enters the robot joint business with its AXIUM actuator brand as the CLOiD home robot makes its CES debut

LG Electronics used CES 2026 to put two robotics bets on the table at once. On Jan. 4 the Seoul-based company presented LG CLOiD, a wheeled home robot with two seven-joint arms and five-fingered hands, and in the same announcement introduced LG Actuator AXIUM, a brand of robot joint modules that it said targets the wider robotics market. The robot drew the crowds at its Las Vegas booth. The actuator brand is the move with more commercial weight, because it puts one of the world's largest appliance makers into the component that its own peer, Hyundai Mobis, describes as the largest cost item in a humanoid.

The numbers LG disclosed were about the robot rather than the part. Each CLOiD arm has seven degrees of freedom and each hand has five independently actuated fingers, LG said. The torso tilts to change height, which lets the robot pick up objects from knee level upward, and a chipset in the head acts as its brain alongside a display, speaker, cameras and other sensors. LG said its vision language model and vision language action model were trained on tens of thousands of hours of household task data.

For AXIUM, LG gave a description but no specifications. The company said each actuator combines a motor that produces rotational force, a drive that controls the electrical signal and a reducer that sets speed and torque, packaged as a compact module that works as a robot joint. In its Jan. 7 CES release LG called AXIUM a cost- and performance-optimised platform built on its experience designing appliance motors, and listed light weight, compact size, high efficiency and high torque as its advantages. It did not publish torque ratings, weights, prices, a production site or a customer.

The CES demonstrations were domestic. LG said CLOiD would take milk from a refrigerator, place a croissant in an oven, start a laundry cycle and fold and stack clothes, tied into its ThinQ smart home platform. The company said it designed the robot with a low centre of gravity for safety around children and pets, and that it plans to keep developing what it calls Appliance Robots and Robotized Appliances on the way to a home where chores are automated. Steve Baek, president of LG's Home Appliance Solution company, said CLOiD was designed to engage naturally with the people it serves.

The launch builds on two years of deal making. LG bought 21% of Silicon Valley service robot maker Bear Robotics for $60 million in March 2024 and in January 2025 exercised a call option to lift its stake to 51%, moving its own CLOi commercial robot business into Bear, according to LG. Ahead of CES the company said it had set up an HS Robotics Lab inside its Home Appliance Solution company to develop robot technology and pursue partnerships.

The money for all of this comes from appliances. LG reported 2025 consolidated revenue of KRW 89.2 trillion and operating profit of KRW 2.48 trillion on Jan. 30, 2026. Its Home Appliance Solution company, which houses the robotics lab, earned KRW 1.28 trillion of operating profit on KRW 26.13 trillion of revenue, while the TV business lost KRW 750.9 billion. The company's 2026 outlook in that release focused on AI appliances, air conditioning and data centre cooling, and software-defined vehicles, without a robotics target.

LG is not alone among Korean groups. Three days after LG's CLOiD announcement, Hyundai Mobis said it would supply actuators for Boston Dynamics' next-generation Atlas, calling it the parts maker's first official robotics customer and saying actuators account for more than 60% of a humanoid's material cost. Samsung Electronics said on Dec. 31, 2024 it would raise its stake in Rainbow Robotics to 35% from 14.7% and set up a Future Robotics Office reporting to its chief executive. Hyundai has a captive buyer in Boston Dynamics and Samsung has an in-house robot maker. LG's actuator, as described at CES, has neither yet.

The technology is familiar to anyone who builds washing machines. A humanoid joint is an electric motor, a controller and a gearbox, and the engineering problem is packing torque into a small, light housing that survives millions of cycles at a price buyers accept. Appliance makers already run high-volume motor lines and the quality systems that go with them. What they have less of is reducer know-how, the precision gearing that Japanese specialists such as Harmonic Drive Systems and Nabtesco have long dominated, and LG did not say whether AXIUM's reducers are made in house.

The risks follow from what LG left out. Without published torque density, weight or price, outsiders cannot compare AXIUM with joint modules from established suppliers, and a captive customer base is the usual way a new actuator supplier proves durability. CLOiD itself carried no price or launch date, and home robots have a long record of impressive demonstrations that never reach shops.
