ball and beam system
thingiverse
This is a precision beam-and-ball system designed to accurately control the position of a 2.5cm ball. To operate it effectively, you'll need a high-performance DC motor (see attached image) and a sturdy 15mm outer diameter bearing, along with a shaft that matches the inner diameter of the bearing. A Sharp distance sensor will also be required to measure the precise distance between the ball and other components. Each part must be printed separately to ensure optimal performance.
