Here are a few of the robots in attendance at BarBot 2013:

Schrödinger’s Martini, in which the amount of vermouth is indeterminate until box is opened and the drink observed.

Thinbot, pouring impeccably mixed drinks with style.

Manhattan Project and Mai Tai Project.

Outta Time, with a new LED lit control panel.

Tipsy Bot, using Legos to tip ingredients into your glass.

Our very own Drink Making Unit 2.1.

SW500 500SW (5:00 Somewhere) became affectionately known as Drink Drink Revolution or Dance Dance Intoxication. It judged your dancing skills and served you a drink thematically appropriate to your style.

Santa Barbot mixes drinks with super soaker components.

Not all the robots were serving drinks, and this lampshade-wearing robot seemed like it may have had a few too many.

No party is complete without R2D2, who wasn’t being used as a roving drink tray, since there were plenty of other robots to serve the humans.

Updated Nov. 9 to correct 500SW’s name.
