#Robot

A script that controls pumps for a cocktail making robot

---

##Terminology

• Robot - One complete unit powered by a raspberry pi. A robot is made up of two machines, a button and a light.
• Machine - A set of three pumps. Three drinks can be mixed together to make a cocktail.
• Job - Instructions to make a drink. A recipe is a list of pump activation times measured in milliseconds.
• Cocktail - Mmmm...

##Description The robot.js script runs on a raspberry pi using Johnny-Five and communicates with a cocktail-control server using MQTT.js.

When the button is pressed, the robot notifies the control server that it is ready to receive jobs.

test_job.js is a script that can be used to send test jobs to the robot without needing to start the entire control server.

Repos

• cocktail-control - The control server.
• workaholic-ui - A web interface for ordering drinks.

Branches

• relay - One of the robots was built using relays instead of transistors so we needed to change some code.
• reversed-light - We mistakenly soldered some of the led circuitry on a robot in reverse i.e. on = off && off = on.

Special Thanks

• Matteo Collina for his work on the cocktail-control.
• Glen Keane for creating the workaholic UI.
• Marco Piraccini for lending us his electronics genius.
• Julian Cheal for coming up with the original idea, building a relay based robot, and contributing to the code.
