Week's Assignments
As a group:
- Design a machine that includes mechanism + actuation + automation.
- Build the mechanical parts and operate it manually.
- Document the group project and your individual contribution.
Mechanical Design
Group Work
For this week’s assignment, we formed a group of five: Gleb, Marjo, Perttu, Lukasz and me. We needed to design a machine that includes mechanism, actuation and automation, build the mechanical parts and operate it manually and document the group project and your individual contribution.
We designed and built a tablet dispenser, whose shared work page can be found from here. The user puts a cup of water in the machine and pushes the button. The machine drops a tablet in the water, preparing a ready drink.
My Contributions
Marjo designed the structure of the machine and made the first prototype using ‘Inkscape Tabbed Box Maker’. As she has mentioned in her page, after laser cutting and assembling it with the motor and dispenser, we noticed that some design modifications should be done. Therefore, I redesigned the parts for the box again from the scratch in Inkskape. Fig. 1 Shows the redesigned parts, and Fig. 2 shows these parts after they were assembled in the final design. These final design file are added to the group work page.

Figure 2. Assembled parts.
The machine also had a mechanical part to pick just one tablet from the stack of the tablet holder. This element was controlled by a servo motor that Lukasz was going to 3D design and print. However, to be sure that the idea works flawlessly, I designed and laser cut a prototype of it (Fig. 3).

I also helped in assembling the final design.
