The humanoid robotics revolution is just around the corner. Test models are already working in factories alongside human beings across the world, while AI companies develop new foundation models designed to help robots navigate their environments as easily as humans do.
But computer “brains” are useless without the skeletons that give humanoid robots their form—and the many components that make up those skeletons need to come from somewhere. Alongside bearings, which reduce friction, motors, and gears, the average humanoid robot relies on dozens of screws—key components that convert the rotational motion produced by a motor into linear motion.
Traditionally, ball screws—which feed a series of balls through a screw shaft and nut—have been the primary type used in robotics. But a new component is set to supercharge humanoid motion and could become the next must-have physical part.
