Week 11
Mechanical Design & Machine Design
Individual Assignment
My role in the machine was to make the mixing mechanism, so I started the design my using 1 DC motor to reciprocate and rotate.

New mechanism
But unfortunately it didn't work so I changed the design to another one with a stepper motor to lift the mechanism up and down, and the DC to rotate and mix the cocktail.

Printing
Then I started printing the parts on a Prusa MK3 printer with PLA material.

Then I needed to cut some shafts for the guide that the parts were moving on.

Assembling
Here was assembling the whole mixing mechanism.

The mixing mechanism assembled.

After that we had to assemble each one's part to complete the whole machine, as the outer enclosure, X-axis, pumping mechanism and so on. and down here is the whole circuit for the machine.

Final Shape
And this was the final shape of the machine after assembling it.

Testing the mixer mechanism
DC motor and pump working together
The machine working but without the mixer
I hope we develop more in that machine and make all pumps work together with the mixer soon.
Words will be added soon.
