This week assignment is to propose a final project that integrates a range of digital fabrication technologies. Also to answer some question regarding the Final Project() you can check this link to see the full summary).
To answer the question below an to make a plan for my project.
My final project is packing module which packs the workpiece or I can say the product in a box without the help of humans. By using three servos and one distance sensor which will be ultrasonic. So first I will fix the box inside the module then I will put the workpiece and the sensor will detect that there is a workpiece and it will send a message to the side servos to close then retract after that the two servos when they retract they will send a message to the third one which is in the back to close the cover.
Like I said in week 1 I get inspired from Festo stations and modules. Since I trained with these stations for four months I liked the idea of building small systems like factories for the purpose of education. When I was training I didnt work with this module, but in the worldskills competition they reveal Packing module as a new module for the competition so I really liked the idea and decided to make it my first module for my system that I will build this year or the next. Packing module from Festo is the only project I saw I didn't saw any project similar to it.
This final project doesn't need expensive material all the material is in the Fab. For this project, I just want three SG90 9G Micro Servo with Half Rotation, HC-SR04 Ultrasonic Sensor, cardboard as a box, and I will print the Module and the holders using 3D printers.
The servo motors and the sensor from a local supplier. For the cardboard and 3D printers from the fab.

I will make the Full module. I will print the module also I will make two PCB, one for the Servos and the other for the sensor. Also the logo from molding and casting week( which is ready).
I want to finish the two PCB. the one for the sensor and for the servos. Also to adjust the design of the project then print it.
I finished The servo board and the sensor you can chick them in input week and output week.
For now is how to make the PCB for the three servos, I mean which microcontroller is the best and at which pin I can connect them?
The schedule is to finish the servo PCB from output week. I started searching for it last week. After that I will make the PCB of the sensor I will put the code and the schematic in input week it will not take time.
Then I will redesign the project the moment I finish with these two PCB. Then I will print the design and while trying to find the best design I will make the networking.
Finally, I will make the sticker at that time I will see the full project in front of me which will give me better ideas on what sticker I need.
The evaluation is when I put a workpiece and the sensor sensing the workpiece and send a message to the servos to close the box and pack the workpiece.
