HD Hyundai Robotics, the robot solutions affiliate of HD Hyundai (267250.KS), invested 13 billion won in Aidin Robotics to secure humanoid robot technology and strengthen its position in physical AI, which enables machines to perceive, interact with and control their surroundings. The size of the acquired stake was not disclosed at Aidin Robotics' request. Founded in 2019 by Sungkyunkwan University mechanical engineering professor Choi Hyouk-ryeol and his former student, CEO Lee Yoon-haeng, Aidin Robotics develops its own robotic sensing systems, including six-axis force and torque sensors exported to 10 countries. The companies plan to integrate Aidin Robotics' force and tactile sensors and control technology with HD Hyundai Robotics' platform, develop a five-fingered hand for humanoid robots used in shipbuilding and heavy industry, and create surface treatment automation for polishing and grinding. Aidin Robotics also attracted 3 billion won from Samsung Venture Investment, after raising 4.5 billion won in a 2022 Series A and 15 billion won in a 2024 Series B.
