[Edaily Reporter Shin Yeong-bin ] Motion control company SAMHYUN CO.,LTD(437730)is developing six types of actuators for humanoid joints. The company plans to secure drive components applicable to various robots and establish a mass production infrastructure, with a goal of achieving a domestic production rate of over 90%.

SAMHYOON CO.,LTD announced on the 11th that it had been selected as the lead institution for the “Humanoid Joint Actuator Platform Development” project under the Ministry of Trade, Industry and Energy’s “2026 Robot Industry Technology Development Project.”

Actuators are core components that move a robot’s joints through motors, gearboxes, and controllers. They influence the force a robot generates, as well as the speed and precision of its movements.

Through this project, SAMHYOON CO.,LTD will develop a total of six types of actuators, including three types using the quasi-direct drive (QDD) method and three high-backlash drive types. Backlash refers to the characteristic whereby the drive unit moves in response to a force applied to the joint from the outside.

The project will run through December 2029, with a total R&D budget of approximately 3.6 billion won. The company aims for a localization rate of over 90% and performance on par with global industry leaders. It also plans to standardize specifications and interfaces to ensure compatibility with various humanoid platforms.

SAMHYOON CO.,LTD will leverage its integrated design capabilities for motors, gearboxes, and controllers—as well as its quality and mass production expertise—accumulated in the automotive industry. According to the company, it unveiled 12 models of its “AXLON” humanoid joint actuators last July and secured an order in September for the initial mass production batch destined for North America from a global humanoid robot client.

For this project, Samhyun will conduct performance testing and verification in collaboration with the Korea Institute of Machinery and Materials (KIMM) and Sejong University. The company plans to expand its product lineup and mass production capabilities to meet the specific needs of individual robot manufacturers, with the long-term goal of expanding into a smart actuator foundry business.

Park Ki-won, CEO of SAMHYOON CO.,LTD, stated, “Being selected for this government-funded project will serve as an opportunity to further advance core humanoid drive technologies based on the motion control technology and mass production capabilities SAMHYOON CO.,LTD has accumulated over the years.” He added, “We will secure world-class actuator technology and contribute to strengthening the competitiveness of the domestic humanoid industry’s supply chain.”
