Your motion will be hand-powered, you cannot touch the gear directly e.g. some knob should be added to actuate the gear. It should have affordances to allow and indicate it is designed to be turned ergonomics should be considered. 

Output motion should be highlighted by physical design (e.g. add something at the end of your linear motion apparatus that shows off your design).

Simplicity is key here, We are looking to prototype something that works well so we can understand the various issues with creating a mechanical drivetrain. 

The design may incorporate 3D printed parts or other hardware but must contain at least one laser cut gear or cam.

All laser-cut parts should be sanded (wax or sealant is suggested also).

Phase 1 Deliverables 

• • All laser-cut parts for the project

  • A page of sketches showing design and how it works

  • List of materials needed or used in the making of project.

    We will meet in class on July 19 to go over the designs, answer questions, and have a work session.

Deliverables (Due July 24 @ 11am and Write Up @11:59PM)

• PRESENTATION (15 pts) July 24, 11am

  • The mechanism must be mounted to a base.

  • Bring your mechanism and nameplates. Your prototypes should be on the Critique Table no later than 1 PM with your new nameplate. Late assignments will not receive a Presentation grade. 

  • Keep your nameplates at your table and add your presentation nameplate with your mechanism. 

  • Projects will be graded on creativity, use of materials, completeness, linkage and gear ergonomics, aesthetics, and attention to detail. 

• WRITEUP (15 pts) Due July 24 11:59 pm

Include the following:

• • Title of Piece

  • Your Name

  • PROJ 04 - Gears, and Linkages

  • DesInv 22 Su23

  • Film a short clip of your rotary to linear motion mechanism in action. 

  • Stabilize your camera. Shaky videos will be docked heavily. 

  • Use landscape orientation. No vertical format videos (record video horizontally to be played back on a monitor screen, not a phone).

  • Include a title slide

  • Product shot ( at least 1 photo)

  • Process photos (at least 2 photos)

  • Process & Description

  • Bill of Materials

  • Adobe Illustrator Laser Cutting File

  • Describe your rotary-to-linear mechanism.

  • Reflect on your process: What surprises did you encounter when making your prototypes? What parts were the most frustrating? How might you approach it if you were doing it again?

  • Add a citation where relevant.

Submit your PDF by July 24 @ 11:59PM.
