Video: Korean humanoid robot pulls off 88lbs bicep curls like a pro

The Korea Atomic Energy Research Institute (KAERI) has developed a humanoid robot named ARMstrong Dex, designed primarily for disaster response and hazardous environments such as nuclear power plant dismantling. A recent video demonstration showcased the robot performing human-like bicep curls lifting approximately 88 pounds (40 kg) per arm, highlighting its strength, control, and mechanical stability. Although this test represents a fraction of its full lifting capacity—up to 441 pounds (200 kg) per arm—the exercise emphasizes the robot’s fine motor control and safe operation, crucial for handling delicate tasks in dangerous conditions. ARMstrong Dex is a human-sized, dual-arm hydraulic robot equipped with dexterous manipulators and caterpillar tracks for mobility across rough terrain. Its capabilities include manipulating valves, plugging cords, carrying debris, and operating tools such as spray guns, making it versatile for disaster relief and nuclear decontamination tasks. KAERI has licensed its technology to robotics firms for practical applications, and the robot serves as a research
