Week 10

Design a machine that includes mechanism + actuation + automation + application

Build the mechanical parts and operate it manually

Actuate and automate your machine

For our group assignment, we're building a 3D scanner designed to capture detailed models of objects. Our machine features a rotating platform where objects are placed, allowing for comprehensive scanning from different angles. Additionally, we've incorporated a curved motion arm that holds the scanner, enabling precise movement along the z-axis. This setup ensures we can capture intricate details and create accurate 3D models of scanned objects.

My role:

• Integrated Mechanical, Electronic, and Control System Components: I were responsible for integrating all the components, ensuring they work together seamlessly.
• Final Assembly: I was responsible to lead the assembly of all parts of the machine.
• Testing of the Complete System: I conducted tests to verify that all components function correctly together.
• Research on Similar Projects: I researched similar projects to gather ideas for improving our initial designs, including studying Quentin's final project.
• Assisting on designing: I designed the stepper motor holders

Firstly we distributed our work amongst ourselves in which my role is to integrate the mechanical, electronic, and control system components. This includes final assembly, testing of the complete system, and ensuring that everything works together seamlessly. And to find similiar projects like our 3D scanner to get more ideas to further improve our initial designs.

We found many projects that were similiar to ours using the Fab Academy search bar using keywords relating to our project. The most similiar and informative was Quentin's final project

We also had to test the outcomes of different ways of scanning our object since we are planning on using a mobile phone and Poly cam software for 3D scanning.

Testing multiple times in differnt ways to find the best one

This is Yangtshel, holding the scanner still, while I move the object. Thank you Yangtsehl for holding the camera very still!

Testing the best way on the fabricated gears.

Tested the fabricated parts as well

Moving the scanner fast in a fixed position and keeping the object still.

Keeping the object still and moving the scanner around the object in different positions.

Moving the object in a moderate speed and keeping the scanner still in a fixed position.

We concluded that the 2nd test(Keeping the object still and moving the scanner around the object in different positions) has the best outcome.

Change of plans

We will be spinning the platform the object will be placed and the scanner will stay stiil in one place but, moving only vertically. We placed an object in the prototype of the platform and scanned the object.

The scanner was placed 10cm away from the platform and moved to an angle of approximately 50 degrees and 72 degree

The result is as follows: For our gear design we used the Involute Spur Gear Builder v2.0 We chose this gear design

I designed the cases for the stepper motorThis design is for the stepper motor for the pulley

This design is for the stepper motor for the base.

Assembling all the parts

Final testing for the scanner in the process of assembly

Drilling for spaces for switch and the other electrical components
