For the final project, I mashed together a few of the ideas I had been exploring. Both the a wall-mounted kinetic sculpture with linear motion and the scissor mechanisms made their way into this piece.
A rack and pinion are driven by a stepper motor controlled by an Arduino micro-controller. The linear movement of the rack is translated into rotational movement around fixed points at the ends of connected arms.
As the rack and pinion move up and down the scissors open and close, creating interesting geometric formation. If I were to move forward with this idea, I’d develop a more elaborate system of scissor arms so that the translation of the linear movement creates wildly expanding and contracting motion in the arms.
