Week 8 - App Implementation
We have hooked the mobile app to our Firebase backend. All that's left is for the RaspPi to fetch from the database as well. The order...

Week 7 - Weight-Controlled Fluid Dispenser
Using a load sensor, we can dispense precise amounts of fluids by mass. By putting together this system with the pneumatic valve system,...

Week 7 - Liquid Pumping Systems are Go!
In addition to solid toppings, we also need a way to add the sweetener (simple syrup) and tea. For this, we use a pneumatically actuated...

Week 6 - Testing the Toppings System!
This week we assembled the control box assembly, microcontroller, motor controllers, and the Raspberry Pi 3B+ that we are using to run...

Week 7 - Mobile App
This is my first time coding a mobile app. So, I picked Flutter as the framework to work with as I have heard good things about it. The...

Week 6 - UI Design
Since we're almost done with the firmware, the next step in the roadmap is building the app for ordering. Before starting to code, it's...

Week 5 - Firmware Implementation
During this week's meeting, it has come to our attention that some of the motors will have rotational limit due to mechanical...

Week 4 - Carriage Assembly Completion
Week 4 marks the completion of one of the primary subsystems: the motion system and topping portioning carriage. This assembly moves...

Week 4 - Firmware Safe Zone Implementation
Since the top of the dispenser interferes with the topping tubes, it was necessary to limit the movements of the dispenser to be within...

Week 4 - Gearbox design
In order to drive our new topping dispensers, we need a driving stepper with a matching dog-tooth clutch. However, there's a slight...

Week 3 - Topping Dispensers
Topping dispensers are critical - we need a way to dispense a precise amount of toppings using a single motor. From our preliminary...

Week 2 - Serial Communication
A serial communication has been established between Raspberry Pi and Arduino. The set of commands are: G1 X Y - move to x mm y mm M0 T D...

Week 2 - Load Cell Mount and Testing
As part of our machine design, we are using a load cell to control how much fluid / topping we dispense in our cup. We purchased a TAL221...

Week 3 - First Test
We hooked up the gantry motors to the control board of a 3d printer, just to test movements while we develop our own firmware. Success!

Week 2 - Cartesian Movement System Assembly
A major part of our system is the cartesian movement system which retrieves toppings and dispenses them. The whole gantry slides into...
