Description
Cocktail Masterclass with Ruby and Friends by Julian Cheal Welcome to Nashville, Tennessee! Have you ever wanted to try making aTennessee Two Step Cocktail, an Old Fashioned, or a Citrus peach cooler for the non-drinkers? Well now you can! Introducing Ruby Mixologist the world's first (probably) Ruby cocktail maker. Ruby Mixologist is a cocktail robot tending to all your drink needs. In this talk we will discover how you too can build your very own Ruby powered drinks robot. #confreaks #rubyconf2019

Summary
Markdown supported
In this video, Julian Cheal presents a quirky and innovative project: creating a robotic cocktail maker named Ruby Mixologist, which utilizes Ruby programming, Raspberry Pi, and Kubernetes. He begins by sharing his background as a Ruby developer from Bath, England, and expresses his love for robotics and cocktails. He initially drew inspiration from YouTube robotic creator Simone Giertz and his experiences at a local bar with talented mixologists. Motivated to solve the problem of not having cocktails on demand at home, he decided to build a robotic bartender using his technical expertise. Key points covered in the talk include: - **Project Inspiration:** Julian's admiration for Simone Giertz's 'shitty robots' and his passion for cocktails led him to automate drink-making. - **Technical Foundations:** The project integrates several technologies: Raspberry Pi for hardware, Ruby for programming, and Kubernetes for managing containers. He specifically highlights the use of K3s, a lightweight version of Kubernetes suitable for IoT devices. - **System Components:** Julian describes the essential components for the cocktail robot, including: - **Peristaltic Pumps:** Used to control the dispensing of liquids. - **Messaging System:** He incorporates Apache Kafka to manage drink orders and updating the system efficiently. - **User Interface:** A Rails app provides a user-friendly interface to track drink orders, which incorporates a state machine for managing the status of each cocktail. - **Challenges and Considerations:** Julian reflects on the ethical implications of his robot potentially displacing bartending jobs but reassures that the robot won’t match the skill of human bartenders. - **Future Aspirations:** After his presentation, he shares how he has attracted interest from a venture capitalist, indicating potential for future development and deployment of the cocktail robot. In conclusion, Julian Cheal's talk at RubyConf 2019 showcases not only his technical capabilities but also a humorous and creative approach to robotics. His cocktail robot is a convergence of various technologies, embodying both functionality and entertainment. As he continues to refine the robot's capabilities, the project stands as an example of how programming and engineering can creatively intersect with leisure activities like cocktail making.
