Assignment requirements:

Group Assignment

• design a machine that includes mechanism+actuation+automation+application.
• build the mechanical parts and operate it manually.
• actuate and automate your machine
• document the group project and your individual contribution

In this week we worked as a group to design and operate a machine, First step we wanted to decide what will we do.

Idea & Tasks

We have gone through several ideas then we found that Luc Hanneuse & his team worked on a cocktail machine which we liked and wanted to make a similar machine with more features.

The machine is a Cocktail mixing machine which we will provide with 3 different liquids, user will choose from an interface the desired cocktail and the machine will produce it.

Machine's features:

Choose a drink from the menu.

Actuate mechanism to pour a drink.

Then we listed down each machine part and each of us took a specific task, mine is:

Pouring Mechanism

Design

Fabrication, Assembly

Programming (Open, Close)

Calibration and Testing

Documentation

Syringe Mechanism

I found someone who made an extruding Mechanism using stepper motor and a big syringe, I liked it and tried to make a similar one. Syringe mechanism video.

I made the design, downloaded some ready models for stepper motor from grabcad.

Sadly, we couldn't find a big syringe to make this mechanism usefull so I switched to pumps

Pump

I choose a pump and assembled it with a bottle to check the dimensions and determine the fixing orientation.

After first test It came out that the pump couldn't suck the water to it's input so I rotated it and the bottle upside down to make the pump always feeded with liquid.

Testing

I tested pumps first with on/off code through mosfet and tested few orientations to check how should I fix it.

Integration

Assembled pumps with the body and tested.

Final test were everything worked together and doing one operation
