BaR2D2 is a robot that isn’t commercially available, but that can be built in the mad scientist’s laboratory that is your garage relatively cheaply. It’s motorized so that it can both wheel over to where you are and then use an internal elevator to raise your beer out of its cooler. Or perhaps you’d like something stiffer? Then make use of the motorized ice/mixer for a cocktail of your choice. Choose your six favorite liquors, load them into the shot dispenser. BaR2D2 is the modern space gentlemen's best friend.
And, make sure you keep the safety on your blaster. Drinking and blasting accounts for over 10,000 human deaths in the galaxy each earth year.
