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 presentation 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 (options include a punch card)

Stretch Goals

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

Project Management

Makers

Major contributors:

Daniel Swann
Ed Raisin
Ian Dickinson
Michael Erskine
Mouse

Collaborators wanted! We're moving from prototyping individual parts to putting the machine together now. Task with which we could use help/collaboration:

Web interface
Frame building (box steel frame)
Thematic design
Power system

See also: Makers page to see who's doing what.

Meetings

Meeting are at 19:30 on Thursdays at Nottinghack, change announcements will be via the Nottinghack mailing list.

Mailing List

To communicate with the makers online, please join the barbot mailing list.

Project timeline

The goal is to have a working robot to take to EM Fields which is at the end of August 2014. More details of sub-project deadlines / goals on the BarBot/Project timeline page.

Purchases & Expenditure

I'd like to keep track of how much is spent on what so I can look back at the end of the project and have a good idea of what it costs to do something like this. I'd also like to reimburse anyone who spends more than their fair share. Please track expenditure on the Purchases and expenditure page.

Design

Dispensers arranges in a line, dispensers are static
Glass on moving platform, which moves along a makerslide (1.5m length)
Dispensers of various types:
- Optics for booze
- Pressurised dispensers for carbonated and other mixers
- Squirters/dashers to add a little bit of something (limejuice, tobasco and such)
- Big syringe for grenadine, because big syringes are cool

Stations and postions

Distance is from the far left. and to the centre of each station.
For coding distance from end stop subtract 105 mm Actual drop position for the umbrella may be.

3	305	Optic
4	405	Optic
5	505	Optic
7	605	Optic
8	670	Mixer

10	790	Mixer
11	850	Mixer
12	910	Mixer
13	970	Mixer
14	1030	Dash
15	1090	Dash
16	1150	Dash

18	1265	Lemon
19	1320	Stirring device
19	1375	Syringe
20	1415	Umbella (Last posible station distance)

See separate pages with details of each device Project:BarBot/Components

Fundamental sub-projects

Dispensing ingredients
Delivering ingredients to glass
Post-processing: stirring / shaking etc. (stretch goal)
Control software
- Database schema for storing recipes & system config info
- Real-time software control (motor control etc.)
- User interface (web-based)
- Ingredient set-up interface
- Recipe execution software (convert recipe into h/w control sequences)
Power system 12V battery & mains operation
Styling and flair
Recipe collection

Supplies for EMF Camp

I want to take a bunch of drink to EMF camp and serve free cocktails. The gifting culture is a wonderful thing, and necessary to avoid conflict with the event licensed bar, but it means we have to fund-raise before hand do buy the stuff. We'll have to fork out for:

Spirits
Mixers
Disposable glasses
Cocktail umbrellas and such (well, we don't have to - we get to)

Bistromathics

I want to serve on Friday and Saturday nights, for about 3 hours per night. I think we can probably serve one drink every 2 minutes, which means we're going to get through about 150-200 drinks. Assuming 200, with an average of 2 * 25 ml shots per drink, and 50ml of mixer, that's:

10 litres of spirits = about £150
10 litres of mixers = about £10-20
About £60 for nice disposable glasses or about £20 for less nice ones. We can have a mixture of them.

Basically, we're looking at a £200 bill for all this if we're going to get cheap booze... more money means better quality boozes.

Costs & Fund-raising

Building the whole thing is going to cost moneys. So far (as of June 11th 2014), people who are working on the project are buying components they need them, and (I hope) filling in the Purchases and expenditure page. However, costs are going to mount and I'd like to reimburse people for the money they've spent. We also need money for supplies, and to pay for a van to take everything to EMF camp.

Potential Funding Sources

I'd rather not pan-handle, so here are some other ideas:

Solicit moneys from the space as part of the EMF camp efforts. This has already been provisionally agreed in the case of hiring a van, and in return I have offered to provide a service to the space by taking larger items of infra for the event, and perhaps tents and other large items for members who are attending.
Poker nights at the space: £10 buy in, £5 goes to BarBot funds.
