Week 12 – Mechanical design, Machine design
This week is about making a machine in a team 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
- 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.

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
