South Korea's KAIST humanoid robot shows off moonwalk and soccer skills

South Korea’s KAIST Humanoid v0.7 robot, developed by the Dynamic Robot Control & Design Laboratory (DRCD Lab) under Dr. Hae-Won Park, demonstrates advanced locomotion and dexterity through a recent field test video showcasing its moonwalk and soccer skills. Weighing 165 pounds and standing five-foot-five, the robot uses Physical AI to autonomously perceive and execute complex actions such as running, jumping, shooting goals, and dancing fluidly. The robot’s hardware—including motors, gearboxes, and motor drivers—was independently developed to optimize torque density and power-to-weight ratios, critical for high-speed and balanced movement. Its actuation system employs a Quasi-Direct Drive (QDD) architecture with a custom 3K compound planetary gearbox, enabling precise control and responsiveness while maintaining a lightweight, efficient design. The robot can run at speeds up to 7.3 mph (3.3 m/s), climb steps over 12 inches, and deliver peak
