Answering:
What will it do?¶
I plan to make the machine that makes the artworks automatically by dropping the liquid colored inks on the paper. I called it, Geodrop. The Drop position is controlled by using CoreXY platform which is the slider mechanism applying to 3D printer and Pen Plotter.
The most outstanding feature is that the machine receives GPS data which is sent from a smartphone and plots inks based on those GPS data. That means the painting is different depend on where I am.

Who’s done what beforehand?¶
Drawing Machine is also the drawing machine that draws the abstract artwork by using stepping motors. And Pen Plotter uses the same positioning technique, using CoreXY system. But I’ve never seen the example of applying the GPS data-based controlling system to those machine and it’s also one of the outstanding features for Geodrop.

How much will it take a time to make?¶
| Process | Time (day) |
|---|---|
| Think the design & concept of the product | 3-5 |
| 3D modeling of the product | 2-3 |
| PCB design and making | 4-5 |
| Core XY | 7 |
| Table(with a drawer) | 5 |
| Integration | 3 |
| Total | 24-28 |
I think it takes more time for people who make it for the first time. Actually, it took more time for me to make it…
And you need to think about the lead time of supplying the materials, especially it took a long time for me to prepare the materials of Core XY.
How difficult could be to replicate your project?¶
The designs of the table and core XY are relatively simple and easy to make as well as the PCB design. I think programming would be the most difficult part in my final product.
For the first idea, I wanted to make the artworks by dropping the several colored inks (Motor control) with the algorithm which creates 10 - 15 drop points (simple algorithm) based on the GPS data (WiFi communication).
But actually, I’ve only done that the machine drops the one colored ink at the point(End effector of Core XY couldn’t move around the drawing space)…
What questions need to be answered?¶
- Technical things
- Do I need Pump?
- How should I use input devices
I may use light sensor and temp. sensor to recognize night and day or more detail. Or I use switch for input device.
How will it be evaluated?¶
-
What percentage did I complete to make my final project?
Each process and function should be evaluated. So I’d like to evaluate along with the below aspects;
WiFi Communication, Data Conversion, Output control (CoreXY, Pump), Table -
Beauty of appearance of my final project
I’d like to check how much the appearance of the machine is cool. It’s almost about design issue. At the academy, I’ll evaluate it by myself, and then someone like my friend will evaluate it.
Project’s Composition:¶
- 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.
Note
Where will the input device be incorporated on my final project?
Switch is one of the input device so Sashatkit already has the slide switch on that board as the mode switching. I think that meets the requirement but if I have enough time to add the other input devices, I’d like to add the photosensor to sense the brightness of my house and reflect it to the artworks that the machine makes.
