Linkage is the mechanism I worked on for the assignment, which is related to the lever.
Definition: A linkage is a mechanism formed by connecting two or more levers together. Linkages can be designed to change the direction of a force or make two or more objects move at the same time.
Four of the main linkage types are the Reverse motion, Parallel motion, Crank and Slider linkage and Bell crank linkage.
Sketch 1:
The parallel-motion linkage is devised to be driven by 2 wheels and a string.
Materials: cardboard, straw, cord, pin
Prototype 1: I only found 1 straw, the first prototype is a half parallel-motion linkage. 😭 But you can see the it works.
Sketch 2: Iterating on the first sketch, I try to add the reverse-motion linkage into the system.
Prototype 2: Using the cardboard instead of straw.
The movement reminds me of a game called “Whack a Mole”.
