Wonik Robotics Seeks to Supply Humanoid Robots to Samsung Chip Plants
Wonik Robotics is seeking to supply humanoid robots to Samsung Electronics' semiconductor plants.
"We are currently conducting proof-of-concept (PoC) testing of wheeled robots with Samsung Electronics and other major semiconductor companies," Wonik Robotics Executive Director Kim Min-cheol said at the Korea Semiconductor Industry Association's Advanced Sensor Forum held at Josun Palace in Seoul's Gangnam district on Sept. 15.
Samsung Electronics' evaluation consists of three stages. It first checks whether the robot operates properly and then evaluates its reliability. During reliability testing, Samsung examines whether the robot can handle variables that may arise when handling wafers, including minute vibrations and dust. Semiconductor plants are highly sensitive to vibration and dust, creating a high barrier to the adoption of humanoid robots.
Even if the robot passes Samsung Electronics' final evaluation, the initial supply volume is expected to be limited. "If we pass, it will be meaningful in that we will have secured a major corporate customer," Kim said. He did not disclose the expected supply volume or timing.
Wonik Robotics' robot is wheeled. Humanoid robots can be divided into wheeled and bipedal types based on their method of locomotion. Wheeled robots have a human-like upper body but use wheels instead of legs for their lower body.
The robot is designed to transport wafers and other materials inside semiconductor plants, replacing tasks currently performed by workers. Wonik Robotics has previously supplied robotic hands for automation at Samsung Electronics' smartphone inspection lines.
Wonik Robotics develops the robot's body, including its hands, arms and lower body, in-house. The company is considering eventually supplying only the robotic hands while sourcing the remaining components externally. Robotic hands are one of the biggest technological bottlenecks in humanoid robots because they require the most precise movements. They are also among the most expensive robot components.
Wonik Robotics uses a five-finger robotic hand modeled after the human hand. The company also considered a four-finger design excluding the little finger, but opted for five fingers to ensure a stable grip on objects.
A key technology in the robotic hand is artificial intelligence (AI)-based object recognition. Sensors embedded in the hand detect an object's type, material and weight. The robot adjusts its grip strength accordingly, applying more force to heavier objects and less to fragile ones. AI assists in recognizing objects. Wonik Robotics develops its AI models in-house and uses proprietary data accumulated over more than a decade in the robotic hand business to train them.
Wonik Robotics' new plant in Wanju, North Jeolla Province, is expected to serve as its mass-production base for robots. The company has its headquarters in Seongnam and a research center in Anyang, both in Gyeonggi Province. Last month, Wonik Robotics said it would secure 350 billion won in funding from the government for projects including construction of a robotic hand production plant in Wanju.
