Week 12 – Mechanical design, Machine design
This week is about making a machine that has mechanism, actuation, automation, function, and user interface.
The objective is to make machine that covers our previous learnings such as 2D and 3D design for creating machine mechanisms, input and output devices for actuation, electronics and coding for automation, function and user interface.
AI prompt: "can you give me an image by referring below two images, it was week 12 - Machine design week and we made a voice controlled smart rotary table. I am attaching the team photo (me, Ashthami, Ali, Ardra and Micheal) please include all in the image that you make. make the image fun animated and landscape image. we used 3D printer, CNC milling machine, leaser cutter, PCB milling machine. I am also attaching the final rotary table images."
Assignment Overview
- Design a machine that includes mechanism + actuation + automation + function + user interface
- Build the mechanical parts and operate it manually
- Document the group project and your individual contribution
- Document the individual contribution --> my main task was to design a mechanism of the group project and ensure the produced parts of mechanism are well integrated as assembly as per design.

Group Assignment
Our group project is centered around the idea of voice controlled rotary table. The primary idea is to use use it on dining table, however the system is designed as a multi-application propose such as organizing tools, holding art supplies, or managing shared resources in a workspace.
Individual Contribution
I had a responsibility to mechanism design, I chose the mechanical design because I wanted to strengthen my ability to think, design and build mechanism for my future projects. As I already have electrical background I chose the mechanical part of group work.
The challenge is to design a rotary mechanism that gets inside the 18mm plywood thus making rotary table look simple and slim. Therefore, making the complexity hidden behind the simplicity.
Below is the image and video of mechanism packaged inside the 18mm plywood.

Sketching
Hierarchical Assembly Structure
The benefit of Hierarchical structure is that if we update the 3D of some assembly body or component separately then by using Get Latest Version function the body or component update in the main 3D Assembly design.
Bottom Plywood
This is the main component of the turn-table because it holds entire mechanisms together.
The mechanisms includes...
Gear Design
Bearing Modules
Motor Mounting
Acrylic Top and Motor/PCB Encloser
Making
Learning - Projection
when we do projection first we shall have object and then sketch in timeline, if we have sketch made first and object later then we will not have projection of object on to the plain.
Leatning - Joint
Firat make a plane at the level at which we need to place the gears and then make geometry on the plane so that we can joint center of geometry to the center of object.
Create Std_Part library
Make things simple but complexity behind the simplicity
- complexity behind the simplicity
- achieve difiult things
- should looks succesfull
- should looks succesfull
- give a lot of time for video
- video as you go
- Gorgeous looking
- Test Test and Test
