I'll be on a Carnival cruise ship in March! I'll have to look for a robotic bartender, although the main lobby bar tends to have some very attractive personnel staffing those locales. And you'll never get a heavy pour out of a robot.
I spent nine years of my career working for Dean Kamen at DEKA Research & Development. They used technology originally designed for medical devices to dispense liquids in proper ratios for soda dispensers, now commonly used in Burger King restaurants. Not that anyone needs microliter accuracy for a soda.
