Hungry between classes? On this college campus, robot vending machines are delivering snacks to students.

In one of the iconic scenes from the teen movie "Fast Times at Ridgemont High," sun-baked stoner Jeff Spicoli has a double cheese and sausage pizza delivered to his classroom, boldly interrupting his uncompromising instructor mid-lecture. Spicoli was considered a mischievous airhead for flouting early-1980s dining etiquette, but he may actually have been way ahead of his time. More than three decades later, a California campus is embracing a kind of food delivery -- via robot. On Wednesday, students at University of the Pacific in Stockton, Calif., will be able to order snacks and beverages for the first time from a bright-colored roving robot on wheels known as the "Snackbot." Its stout body perched atop six small wheels, the electric Snackbot resembles some combination of an Igloo cooler and a Volkswagen Microbus.
