We have seen the future, and it is Bar2D2. The dude who made it is obviously A) a genius, B) our kind of drunk, C) a man with some time on his hands.
Here's what he told us:
BaR2D2 is a radio-controlled, mobile bar that features a motorized beer elevator, motorized ice/mixer drawer, six-bottle shot dispenser, and sound activated neon lighting. The robot is driveable so you can take the party on the road! It was created in my garage using standard hand/power tools and readily available parts and materials.
