White Russian Hippie Maker - Front by Rich Gibson

Saturday night, April 2, at BarBot 2011. The American analogue of the RoboExotica Show highlighting robots in Cocktail Culture. This year it was held at the new Parisoma work space.

The White Russian Hippee Robot! Magnus was here in San Francisco this year.

Johannes, and Monochrom, have built a wormhole between San Francisco and Vienna. It is great. Robots and people pass through a semi-porous membrane and arrive on one side or another.

Here is how the robot looked at Roboexotica Dec 2009

And if I have anything wrong, please add a comment!)

I love the little details in this piece. Note the grace notes in the snapshots, such as the auger ice feed, the feedback switch on the ice chute so you only get one cube of ice, the fun servo driven selection indicator from 'milk' to 'vegan.'

The valves are made with servo motors attached to chopsticks - when the servo is 'off' it turns the chopstick which obstructs the tube with the fluid flow.

This machine also delivered a quality White Russian. It turns out that I have been using _way_ too much milk in my White Russians. They are tastier this way!

White Russian Hippie
1st Vienna Cocktailrobot Workshop Crew: Heidi Trimmel, Karina Schwarz, Franz Ablinger, Chris Veigl, Magnus Wurzer
This cocktail robot is the outcome of the first Vienna cocktail robotics workshop held in 2009. As the name suggests, it offers the choice between a White Russian or its vegan counterpart - the White Hippie! Made from Arduino processors and found parts, it mixes and serves the cocktail with ice when a glass is placed on the designated platform and a choice of drink made by pressing a button.

My deconstruction...
In terms of Physical Computing and interaction this cocktail robot implements (at least :-)

4 drink selection switches (with four extras on the former elevator pad)

4 servo motor chopstick valves to control proportions of four different liquids

1 servo motor to provide feedback with a pointer whether you are getting a dairy or vegan drink

1 feedback switch to make sure there is a cup in place, so a drink is not wasted onto the floor.

1 DC motor to control the ice augor

1 spinner switch to provide feedback that ice has actually been delivered to the drink.

Possibly a hall effect sensor (or just a magnetic switch :-) to indicate when the ice auger is at the top position, and needs to be reset and refilled with ice.
