BarBot

We want to create a BarBot.

Initial Goals

• 6 Optivends for alcoholic drinks
• 6 dispensers for soft drinks
• 6 dispensers for misc items (olives cherries, umbrellas, etc...)
• High through put with multiple drinks simultaneously

Target Cocktails

• Gin & Tonic
  • Gin
  • Tonic
• White Russian
  • Cream
  • Vodka
  • Kahula
  • Ice
• Margarita
  • tequila
  • line
  • triple sec
  • salt rim
• Mojito
  • Lime
  • Mint Leaves
  • Sugar
  • ice
  • white rum
  • soda water

ToDo

• Block diagram
• Decide on a budget
• Make a makespace community project

Idea Scratchpad

• Force sensitive resistors for glass detection & liquid quantity
• Carriages with scissor lifts to activate Optivends (and thus everything else)
• Circular track/path to automatically reuse a carriage.
• Ways of bypassing unused dispensers to allow for drinks leapfrogging.
• Raspberry Pi for main controller, Arduino-likes for carriages
• 3D print our own peristaltic pumps?
• HackADay links to check out here
• A barbot is essentially a vending machine, mine vending machines for mechanisms & ideas.

Roberts Working Idea

• Standardised glasses, like these or these.
• Glasses are loaded in corner as a stack of 20 in a column
• Glasses travel on large carousels
• Mini-carousels for spirits, lever mechanism to operate Optics
• Peristaltic pumps for soft drinks
• Hoppers and screws for garnishes
• Fits in a transparent ~1 meter cube, interesting things to see from all 4 sides.
• Use a RPi for management, connected to a touch screen for order taking and an RFID reader (TikiTag?) for customer tracking
• Use LIN bus nodes for modular management; a node for cup carousel, a node for a spirit carousel etc...
  • Freescale KL05 FRDM boards for each node, a specialised shield to tailor the node for it's role.
• Lots of sensors for fully closed loop control
