BarBot Project

As per the project announcement on the mailing list, the goal of this project is to create a robot capable of serving (some) cocktails. Some pictures of cocktail robots can be found in the [[1]] shown at open night on 2014-03-26.

Goal

To have a functional booze-serving robot ready to take to EM Fields at the end of August 2014.

Minimal functionality

  • Make drinks from a combination of four or more spirits (six is better)
  • To have some visibly moving part(s) - i.e. not the Bartendro approach where ingredients are pumped to a static glass via static tubes.
  • For punters to be able to choose their beverage interactively some how

Stretch Goals

  • Have options to add mixers (e.g. tonic water)
  • Ice dispenser
  • Make it look pretty

Fundamental sub-projects

Design Considerations

TODO: split this into a separate page

  • timescales - in time for EMF camp?
  • portability and power - bulky?
  • reliability on uptime
  • setup and teardown
  • management of lots of drunken people

Current Work

  • Michael: investigate servo pinch valve
    • this will be timed rather than measured so calibration of each valve is required per ingredient
    • one valve per ingredient bottle
    • Tower Pro SG90 9g Servo - have one for prototyping - DX bulk order - cheap
    • laser cut mech
    • 6mm soft silicon tubing - check HS consumables -
    • Arduino servo control shield and code
    • bottle interface
      • cork/bung with hole - cheap pourers with silicone sleeve
      • bottle is inverted
      • bottle needs holder of course.
      • Bottle holder: hose clamps/rapstraps, presentation aspects, changeability,
  • Michael: investigate peristaltic pumps
  • spills and mess, hygiene and cleanup

I now have 2 types of 6mm tubing: cheap plastic from wilkos and some more expensive silicone tubing from the Range -- Michael Erskine 1 April 2014

I have ordered a cheap 2l bottle fizzy drink tap from a HK ebay seller - these might be a cheap answer for carbonated mixers -- Michael Erskine 1 April 2014
