Humanoid Robot Runs With Human-Like Form at Games

Rohan Paul posted a video from the World Humanoid Robot Games showing a bipedal robot running with a forward lean and active arm swing. The post states that reinforcement learning produced this posture over a more human-like upright form. It notes that a person swings the arms mainly to counter torso twist from each stride, while a robot arm consists of motors, gears, and wires where rapid swinging creates high repeated torque.
