Korean people are famous for having good hand skills, and now this talent is helping robots too. A Korean physical AI startup called RealWorld developed a new robotics foundation model called RLDX-1. On May 7, the company announced that the model ranked first in global benchmark tests.
RLDX-1 was made to help humanoid robots move all five fingers very carefully and naturally. The AI model can listen to human commands, understand objects around it, and decide how to move by itself. This technology is important because controlling five fingers is much harder than controlling only two or three fingers.
Until now, many humanoid robots only used two or three fingers because more fingers require more difficult calculations and control systems. Many companies believed that robot intelligence should improve first before robots could develop better hand skills. However, RealWorld had a different idea. The company believed that robots cannot become truly intelligent without good hand movement and delicate control.
RLDX-1 showed amazing results in eight global benchmark tests. It performed better than famous robotics models such as NVIDIA’s Groot and Physical Intelligence’s Pi-Zero. In one test that measured how robots work in a kitchen-like environment, RLDX-1 scored 70.6 points. It became the first robotics model in the world to pass 70 points in this category. The robot was able to open a refrigerator, take out a cup, and complete simple housework tasks.
In another test, the robot successfully picked up objects from a table by following human commands. RLDX-1 scored 58.7 points, which was 10.7 percentage points higher than NVIDIA’s result. These achievements show that Korean robotics technology is becoming one of the best in the world.
