The humanoid robotics revolution is fast approaching. Across the globe, test models are already working side-by-side with humans in factories, while AI companies race to develop advanced foundation models that enable robots to perceive and interact with the world as naturally as people do. But while much attention is focused on the artificial intelligence driving these machines, their physical forms—the “bodies” that make movement possible—are just as critical.
At the core of these robotic bodies are mechanical components like motors, gears, bearings, and screws. Among them, screws play a vital role by converting the rotational energy of motors into the linear motion humanoids need to walk, lift, or perform delicate tasks. Traditionally, ball screws—which use a circulating track of small balls between a threaded shaft and nut—have been the standard. But that’s starting to change.
