Korea forms K-Humanoid Alliance of about 40 groups, targeting a shared robot brain and sub-60kg, 50-joint humanoids by 2028

South Korea's Ministry of Trade, Industry and Energy (MOTIE) launched the K-Humanoid Alliance on 10 April 2025, bringing the country's robot makers, AI researchers, chip and battery suppliers and factory owners into one programme with a stated aim of making Korea the world's strongest humanoid nation by 2030. About 40 companies, universities and other organisations signed a cooperation agreement at a ceremony at The Plaza hotel in Seoul attended by about 350 people, including Minister Ahn Duk-geun and Seoul National University President Yoo Hong-rim, according to the ministry's release. MOTIE said it expects more than 1 trillion won of public and private investment in R&D, funds and M&A by 2030.

The ministry set five tasks: a shared robot AI model, core humanoid hardware, AI semiconductors and mobility batteries, start-ups and talent, and closer ties between robot suppliers and the companies that would use them. Members sit in six expert groups covering AI development, robot manufacturing, components, demand companies, universities and research institutes, and investment and finance, with a steering committee of group representatives handling coordination. The release's reference list names 15 AI and robotics experts, 12 robot makers, 11 component companies and seven demand companies. The Korea Evaluation Institute of Industrial Technology (KEIT) is listed as the supporting agency.

The alliance's first and, in the ministry's words, most important mission is the robot brain. An AI group built around the Seoul National University AI Institute, led by Professor Zhang Byoung-Tak, with researchers from KAIST, Korea University, Yonsei University, POSTECH, Pusan National University, GIST and Sogang University, plans to develop a robot AI foundation model by 2028 that all member robot makers can use. In return the robot and parts companies are to feed the researchers their robots, motion data and feedback from running the AI on real machines. MOTIE pointed to the queue of robot companies around NVIDIA's Cosmos platform at CES 2025 and to tie-ups such as Apptronik with Google and UBTech with Baidu as evidence that hardware makers increasingly pair with AI developers.

The hardware targets are equally specific. By 2028 the robot makers plan to produce, alone or jointly, humanoids weighing 60kg or less with at least 50 degrees of freedom, a payload of at least 20kg and a travel speed of at least 2.5 metres a second. Makers and parts suppliers are also to co-develop force and torque sensors for precise handling, tactile sensors that give a hand a sense of touch, and light, flexible actuators combining motor, controller and reducer. MOTIE said it would give priority to joint projects between two or more member companies, that its 2025 robot budget is about 200 billion won, and that it would keep negotiating with other ministries and the National Assembly for more. It also plans shared infrastructure, including test sites that resemble real workplaces and a virtual simulator built on video and tactile data, described as a Korean version of NVIDIA's Cosmos, with the project due to start in the first half of 2025.

On chips and batteries, the AI chip designers Rebellions and DEEPX and the three battery makers SK On, LG Energy Solution and Samsung SDI joined to explore joint development with the robot companies, and the ministry said it would run a large R&D programme for on-device AI chips. For start-ups and talent, MOTIE said it would launch a humanoid fund within 2025 and bring about 20 major universities, including SNU and KAIST, into the alliance so undergraduates can take part in its projects. To link suppliers and users it plans regular seminars, showcases and competitions, and from 2025 humanoid projects run jointly by a robot maker and a manufacturer may apply to its AI Autonomous Manufacturing leading project for R&D and financing support.

The robot makers named are Rainbow Robotics, AeiROBOT, Holiday Robotics, Wonik Robotics, WIRobotics, Blue Robin, Robros, Angel Robotics, Neuromeka, Doosan Robotics, LG Electronics and HD Hyundai Robotics. The ministry's profiles note that Rainbow was founded by the team behind HUBO, Korea's first humanoid, and had recently become a Samsung Electronics subsidiary; that Holiday Robotics raised 17.5 billion won within five months of its founding; that Wonik Robotics is developing a tactile robot arm with Meta; that WIRobotics was founded by developers of Naver's AMBIDEX dual-arm robot; and that Neuromeka is running a 10 billion won medical humanoid project funded by KIAT from 2024 with Georgia Tech. HD Hyundai Robotics joined to add AI to industrial robots.

The component list includes Robotis, whose main product is robot joint actuators and in which LG Electronics is the second-largest shareholder after a 2017 investment, SBB Tech, which the ministry says was the first Korean company to develop and mass-produce harmonic reducers, force-torque sensor maker AIDIN Robotics, gripper start-up Tesollo, and motor makers Faraday Dynamics and Komotek. The demand side comprises Samsung Display, which the ministry says runs more than 20,000 industrial robots in its plants, LG Electronics, HD Hyundai Mipo, Samsung Heavy Industries, CJ Logistics, POSCO Holdings and POSCO E&C. Samsung Electronics is not on the member list, but Oh Jun-ho, head of its Future Robotics Office, presented on domestic and global humanoid trends at the launch.

MOTIE framed the alliance as a catch-up effort. Its release lists Tesla, Figure AI, Amazon, Microsoft and NVIDIA as US companies investing astronomical sums and says Chinese start-ups such as Unitree and UBTech are growing fast with state support. Korea, it argued, has technical potential, citing second and third places for SNU and Pusan National University and for Hanyang University at RoboCup 2024, but lacks investment and people. Its patent count for the past five years puts Korea fourth with 368, against 5,688 for China, 1,483 for the United States and 1,195 for Japan. Ahn said humanoids are expected to grow 25-fold in ten years, from US$1.5 billion in 2025 to US$38 billion in 2035, and that the sector is tied directly to the future competitiveness of Korean manufacturing.

In plain terms, a robot foundation model is a large AI model trained on many robots' sensor and movement data so it can be adapted to new machines and tasks, rather than coding each robot separately. Degrees of freedom count a robot's joints, which set its range of motion; payload is what it can lift; and an actuator is the motor, controller and gearbox package that drives each joint. On-device AI chips run that model inside the robot at low power instead of in a data centre.

The risks sit in the wording. The 1 trillion won is an expectation spread across R&D, funds and M&A, not an appropriation, and the ministry gave no breakdown by year or source. The 200 billion won 2025 budget covers all of MOTIE's robot programmes, not humanoids alone. A foundation model built by a university-led group must compete with models from NVIDIA, Google and well-funded start-ups, and keeping about 40 organisations, including direct competitors, sharing data will test the steering committee. The patent gap with China, more than 15-fold on the ministry's own figures, is the scale of the task.

Three weeks after the launch, on 1 May 2025, MOTIE said members had already signed four MOUs, including one between Rainbow Robotics and CJ Logistics to co-develop and commercialise logistics robots. The deadlines that matter remain 2028 for the shared model and the hardware specifications and 2030 for the investment and leadership goals.
