Physical artificial intelligence (AI) corporations Realworld (RLWRLD) unveiled its self-developed Robotics foundation model (RFM) "RLDX-1." The model is designed to implement human-level dexterous manipulation with a robot hand.
Realworld on the 10th demonstrated at "Dexterity Night in Seoul," held at Raum Art Center in Gangnam-gu, Seoul, a humanoid (human-type) robot equipped with "RLDX-1" that picked up a wireless mouse with five fingers and placed it in a box.
Ryu Jung-hee, Realworld's CEO, said, "On the industrial floor today, there are still tasks that require human hands," noting that the goal is to automate precise processes that require human dexterity. Even now, in manufacturing, industrial robots carry out a large share of simple repetitive work, but tasks that require hand motions—such as picking up, assembling, and inserting small parts—remain manual work that robots have not replaced.
Ryu said, "In Korea, 75% of all processes are automated, while Japan, China, and the United States remain at 40%–55%," adding, "Our goal is to automate the remaining labor market."
The "RLDX-1" that Realworld introduced that day is differentiated from existing vision- and language-centric general-purpose VLA models in that it processes not only vision and language but also force (torque) applied to the hand, touch, and working memory within a single model. A Realworld official explained, "To automate precise tasks on industrial sites, it must be able to handle signals that vision alone cannot capture, such as torque, tactile sense, and contact."
The event marked the final stop of a global tour that followed San Francisco in the United States, Tokyo in Japan, and Taipei in Taiwan. Realworld said it chose Seoul as the final destination to position Korea—equipped with strong automation infrastructure and manufacturing competitiveness—as a strategic base for the introduction of physical AI and the spread of the global ecosystem.
The event proceeded in the order of an "RLDX-1" introduction, two panel sessions, and an RLDX-1 technology demonstration. About 350 attendees from large domestic manufacturing and logistics corporations and major domestic and overseas investment institutions took part.
In the demonstration, one robot placed an item on a conveyor belt, and another robot picked it up with a high-degree-of-freedom 5-digit (5-finger) robot hand and put it in a box. Realworld pointed to the strength of "RLDX-1" in not being limited to a specific robot model and flexibly integrating with all hardware.
Ryu said, "This year, we plan to focus on commercializing RLDX-1 and applying it across various industries," adding, "At the same time, we have begun developing the next model, RLDX-2."
Founded in 2024, Realworld is a physical AI corporations that develops a Robotics foundation model to implement human-level hand motion capabilities and cognitive abilities in machines. The company has attracted investment from major corporations in Korea and Japan, including SK Telecom, LG Electronics, CJ Logistics, Lotte, KDDI, and ANA, and is pursuing proof-of-concept collaborations.
