Remember BaR2-D2, the robot that dispenses beer instead of light sabers which Jabba should have had in his barge? Here is a video of the thing serving drinks in a real party.

The BaR2D2 is a radio-controlled bar-bot, with a "motorized beer elevator, motorized ice/mixer drawer, and six-bottle shot dispenser." It's also "sound activated neon lighted", because alcohol delivery is not complete without psychotropic light effects. According to its creator:

The concept for BaR2D2 was born when a friend showed up to an event with a radio-controlled cooler. We joked about taking the idea to the next level and in the Spring of 2008, construction began.

Hopefully, the next one will mix Margaritas, Manhattans, Long Islands, have a pole dancer on top, and they will invite me to a party. [Instructables]
