The Korea Atomic Energy Research Institute (KAERI) recently showcased its humanoid robot, ARMstrong Dex, performing dead-hang pull-ups with a 44-pound (20 kg) weight. This hydraulic powerhouse, built to mirror an adult human in size and dexterity, is being tested for its ability to operate in challenging environments—from disaster sites to high-risk industrial areas.
In a series of rigorous tests, KAERI evaluated critical metrics like joint torque and mechanical stability. These figures help determine how well the robot might handle environments where human responders face risks such as radiation or unstable structures. Beyond just raw strength, the pull-up test was designed to assess ARMstrong Dex’s overall coordination and endurance—qualities essential for navigating vertical obstacles and lifting heavy loads during real rescue operations.
ARMstrong Dex forms a key part of KAERI’s efforts to develop reliable robotic solutions for tasks like nuclear decommissioning. With technology that it shares with the “Big Tex” platform, this dual-arm robot is not only suited for heavy lifting but is also crafted to move easily through spaces originally designed for people. As natural and industrial disasters become more common and severe, innovations like these promise to broaden the spectrum of emergency responses.
