Assignment

Simple Mechanism Prototype

Part 1: Find a simple mechanism, either from your toy, your research group, or another source, and sketch out the mechanism on paper. The mechanism does not need to be complex. What are the components of the mechanism? How is the motion transferred between those components? Add callouts and descriptions to your drawing.

Part 2: Create a working prototype of the mechanism in low-fidelity prototyping materials. Do not use any digital fabrication methods, nor wood, for this mechanism. You should use materials from the list below:

Sheets Forms Connectors Adhesives
Cardboard Foam blocks Rubber bands Hot glue
Chipboard LEGO Pipe cleaners Elmer’s glue
Foam-core Styrofoam balls Paper clips Double-stick tape
Felt Play-doh Florist wire Masking tape
Construction paper Popsicle sticks String Super glue
Aluminum foil Dowels Safety pins Packing tape
Index cards Paper cups

You are welcome to use other materials in the same vane. If you are unsure of a material or process, feel free to reach out to me over DM.

Your mechanism can be either 2D (flat to the table) or 3D (includes vertical supports) but it should be functional. Include a way of activating the mechanism with clear instructions noted on the prototype itself.

Part 3: Post your sketches, a video of your prototype in action and any process documentation you have (please take photos!) to your blog by 11:59pm 9/24. If your blog post link changed for this assignment, please DM it to me.

For some ideas on how to choose a mechanism for your study, look online, look at your inspiration automata, your peer’s inspiration, or this website:
