16. Applications and implications¶
assignment¶
-
Propose a final project masterpiece that integrates the range of units covered, answering:
- What will it do?
- Who’s done what beforehand?
- What will you design?
- What materials and components will be used?
- Where will come from?
- How much will they cost?
- What parts and systems will be made?
- What processes will be used?
- What questions need to be answered?
- How will it be evaluated?
-
Your project should incorporate
-
2D and 3D design,
- additive and subtractive fabrication processes,
- electronics design and production,
- embedded microcontroller interfacing and programming,
- system integration and packaging
Where possible, you should make rather than buy the parts of your project. Projects can be separate or joint, but need to show individual mastery of the skills, and be independently operable.
My Final Projet is AKUNA CUBE¶
What will it do?¶
It is capable of being placed in an environment and taking data such as the temperature and humidity of the soil.
Who’s done what beforehand?¶
she’s made a cube to know whether the plant needs water or not, thanks to a light signal.
BLANCA ROSAS FROM Fab Lab Amsterdam (Pays-Bas)
What will you design?¶
I designed all parts of my AKUNA cube. such as :
ELECTRONICS
- 6 circuit boards corresponding to each face of our cube
MECHANICS
-
the protection box
-
For the application and test of the cube we made a table to illustrate process of inspecting and monitoring various aspects of a farm to ensure its proper functioning and productivity. This may involve regular checks and assessments of factors such as crop growth, soil conditions, irrigation systems, livestock health, equipment maintenance, and overall farm management. Farm checking property aims to identify any issues or deviations from desired standards and implement corrective measures to optimize farm operations and maximize yields.
Informatic
- Create a data exploitation platform.
What materials and components will be used¶
MDF, 3mm for the protection box and 15mm for the table
PLA filament
sensors and electronics components
router
screen module
raspberry pi 4 model B
Where will come from? / How much will they cost?¶
All are either provided by lab.

What parts and systems will be made?¶
We made :
MECHANICS PART
- Box
- Table
- hydraumic instalation of the table
ELECTRONICS PART
- Electronic Cube
- Electric installation for the smart irrigation experiment of the table
INFORMATIC PART
- Web platform for datas acquisition
Things not made are :
- Hydraulic installation is not complete yet. cause we did’nt find the good pipes
What processes will be used?¶
2D and 3D design :
-
Solidworks
-
Inkscape
Additive manufacturing:
- 3D printer
Subtractive manufacturing:
– milling table using Shopbot
-Milling PCB board using Roland SRM-20
cutting:
-Laser cutting with Epilog Fusion edge
Programing :
-
Web Interface programming using JavaScript and Raspberry PI 4
-
Embedded programming using Arduino IDE
-
Wi - Fi communication using xiao esp32C3
What questions need to be answered?¶
Is it Possible to have a cube which can move through all the field to get datas at different points of the field ?
Is it cheaper enough to get many to position them at many point of the field ?
How will it be evaluated?¶
- Accuracy and precision of the datas ?
- Robustness to withstand field conditions
