Four MIT students who once built a soccer ball-kicking robot got together with a Michelin-starred chef to build a restaurant that's not quite what you're used to. How? Well, it's staffed by robots, obviously. Spyce, a fast casual restaurant that has just opened its doors in Boston, has a mecha-kitchen with seven autonomous woks preparing its healthy offerings. A customer simply has to choose one of the bowl-based meals in its menu through a touchscreen kiosk, and the sprouts, kale, beans, grains and other components of the meal will automatically drop into one of the drum-like machines to start cooking.
