Robotic Bartender

cults3d

This is a budget-friendly, energy-efficient bar robot project. Many similar designs exist on Thingiverse, but they often require air compressors, mains voltages, and come with price tags that run into hundreds of dollars or pounds. This design takes a different approach by using most 3D printed parts. It's designed to run from a USB battery pack and some AA batteries, keeping power levels safe when working with liquids and making it easy to take the machine to parties, gardens, or beaches. If you decide to build one yourself, I'd love to see your creation! Here is the Bill of Materials: * Arduino Uno: http://geni.us/ArduinoUno * Motor driver: http://geni.us/UnoMotorShield * Contact Switch: http://geni.us/ContactSwitch * Linear Bearings: http://geni.us/LinearBearings * Stepper Motor: http://geni.us/StepperMotor * Timing Belt and Pulley (2m version): http://geni.us/TimingBelt * Timing Belt and Pulley (5m version): http://geni.us/TimingBelt5m A video guide on assembly is available here: Part 1: https://www.youtube.com/watch?v=NBvXknwVfaI Part 2: https://youtu.be/0t-JTVYdE7s Part 3: https://youtu.be/x-PyuDoUlU8 Part 4: https://www.youtube.com/watch?v=cvOpvPKHJvc I also used the following models created by others: * To hold the Arduino: https://www.thingiverse.com/thing:33327 * For the drag chain: https://www.thingiverse.com/thing:11978 * The threaded rods and paddle threads were made using this thingy: https://www.thingiverse.com/thing:193647 You can find the Arduino code here: http://diymachines.co.uk/?p=62 If you'd like to support me, you can either buy me a coffee at https://ko-fi.com/diymachines or check out our Patreon page: https://www.patreon.com/diymachines UPDATE 12/01/2018: I've been asked to slice up the main slider base so it might be printed on a smaller print bed. I've uploaded files 'Slider Base V3 - P1of2' and Slider Base V3 - P2of2'. I haven't had chance to test these, so if you do print and assemble them without issue, please let me know so I can update this. Thanks!
